via SATellite 1 1.1 Introduction Scope This document is intended for giving system engineers, support engineers, and installation and service personnel the necessary information to plan, install, operate and maintenance a TSAT network. A brief trouble-shooting guide is also included. Technical information about the TSAT system concept, transmission system and communication protocols can be found in the document "TSAT System Description". The Supervisory Terminal and Network Management System is described in the "Supervisory Terminal User Guide". Configuration and diagnostics is described in the "Configuration and Diagnostics Guide". 1.2 TSAT 2150 System Introduction The TSAT 2150 satellite communication network is dedicated to low data rate communication via satellite. The Remote Terminals are controlled by one common HUB Station in a full duplex closed star network configuration, see Figure 1-1. The unique design of TSAT 2150 introduces low-cost solutions to traditional problem areas in low data rate satellite communication, such as frequency stability, phase noise, and interference requirements. Flexible interface and protocol options offer cost-effective communication solutions for data collection, remote monitoring and control and transaction applications. 2 400 – 16 800 Hub Station 1.2 m Remote Terminals 90 cm Figure 1-1 TSAT 2150 Closed Network • • • • • • Low data rate: 2 400 bps – 16 800 bps enables low transponder load. Small earth stations: The HUB Station, with a standard antenna of 1.2 m is comparable in size to the Remote Terminals in traditional VSAT systems (1.8 m and 2.4 m optional). The TSAT 2150 Remote Terminal antennas are as small as 90 cm in diameter. The outbound link, from the HUB to the RT’s, is running continuously, addressing and commanding the Remote Terminals. The Remote Terminals share one or several inbound links either by time division multiplexing or by random access. Any conventional Ku-band communication transponder can be used (uplink 14-14.5 GHz, downlink 10.95 - 12.2 GHz and 12.25 - 12.75 GHz). Closed network: TSAT 2150 is a dedicated, private network. Installation, Operation and Maintenance Guide, August 2006 Page 6 of 42 TSAT 2150 - Telemetry and data transfer via SATellite The TSAT 2150 design allows a complete HUB station comparable in size and complexity to traditional VSAT’s (Very Small Aperture Terminals). Together with the low-cost Remote Terminals, TSAT 2150 requires low investments in earth station equipment. The efficient utilisation of satellite power and bandwidth gives low operational costs, enabling cost-effective solutions even for small networks. The modular design enables large flexibility for future increase in network capacity. Adding more inbound link frequencies, requiring only the addition of an extra main unit in the HUB Station may increase the inbound link capacity. If the network grows beyond the capacity of the outbound link, the network can be divided into sub-networks by adding new outbound links. Possible applications include: • Collection and distribution of data, i.e. environmental, ecological and security surveillance. • Remote monitoring and control (SCADA). • Transaction oriented networks, i.e. credit-card verification, on-line betting.

The antenna site elevation and azimuth angle, and distance to the satellite, can be calculated when the following parameters are determined. • The location of the satellite in the geostationary orbit, normally given in degrees with references (0 degrees) in Greenwich, England. Angle is positive towards east. • Site longitudinal location (degrees). • Site latitudinal location (degrees). 2.2.2 Signal path obstruction The antenna site must have an unobstructed bore sight to the satellite position in the geostationary orbit, as shown in Figure 2-1. An obstruction inside this envelope will result in reduced signal to noise ratio, and increased transmit signal interference levels which are not compliant with ETSI and satellite operator requirements. 1 deg. 2 deg.

The antenna site elevation and azimuth angle, and distance to the satellite, can be calculated when the following parameters are determined: The location of the satellite in the geostationary orbit, normally given in degrees with reference( 0 degrees) in Greenwich, England. Angle is positive towards east. Site longitudinal location (degrees). Site latitudinal location (degrees). The required parameters are: re = 6. 38 • 106 m ( earth radius) rs = 4. 2172 • 107 m ( distance earth center to geostationary orbit) α = lattitude antenna site θ = ( longitude antenna site) - (longitude satellite position in geostationary orbit) The antenna site elevation angle, from horizontal plane, is given by: ε = arctan( ( cosα ⋅ cosθ − re / rs ) / [1 − (cosα ⋅ cosθ ) 2 ] 1/ 2 ) The antenna site azimuth angle, from true north, positive angle clockwise, is found from the equation: a = 180 + arctg( tg (θ ) / sin(α )) The distance to the satellite is given by: [ d = rs2 + re2 − 2 ⋅ rs ⋅ re ⋅ cos α ⋅ cosθ ] 1/ 2 Installation, Operation and Maintenance Guide, August 2006 Page 9 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 2.3 Antenna Mount requirements To maintain compliance with ETSI and satellite operator requirements, the antenna mount must be permanently fixed to a supporting structure that enables the antenna to maintain a stability within 0.5 degrees under normal operating conditions (for a wind speed of up to 30 m/s). In addition, the specification given in ETSI EN 301 428 state that under the condition of 100 km/h maximum wind speed, with gusts of 130 km/h lasting 3 seconds, the antenna or other parts of the structure shall not show any sign of permanent distortion and shall not need repointing after the application of the wind load. A load of 20 mm of ice coating on the antenna surface should also be considered in areas where this condition might occur. The supporting structure should therefore be constructed with this in mind, or existing structure should be examined carefully, before the antenna mount is assembled. Table 2.1 lists the wind load at 50 m/s, and the ice load for a 20 mm ice coating. Antenna size [cm] 55 90 120 240 Wind speed [m/s] 50 m/s 50 m/s 50 m/s 50 m/s Ice load [kp] (20 mm ice coating) 12 32 57 ~200 Wind load [kp] (1 kp ≡ 9.8 N) 47.5 137.3 264 ~1000 Table 2.1 Wind load and ice load The correspondence between various wind speeds, wind loads and antenna diameters can be found from values given in Table 2.1 and the following equation: P1 = P0 ⋅ ( v1 / v 0 ) 2 ⋅ ( ø 1 / ø 0 ) 2 (for circular antennas) where the index 0 and 1 indicates data set 0 and 1: Px = wind load for data set x νx = wind speed for data set x φx = antenna diameter for data set x Installation, Operation and Maintenance Guide, August 2006 Page 10 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 2.4 2.4.1 Antenna mount methods Pole mount The HUB Station antenna diameter is normally 120 cm, and the pole dimension 76 ± 1 mm. Other HUB antenna dimensions can also be used. Larger antennas normally requires other pole dimensions. For assembly and mounting of the HUB antenna see the description supplied with the antenna. The Remote Terminal antenna diameter is normally 90 cm, and uses same pole size as the 120 cm antennas. For assembly and mounting of the Remote Terminal antenna see the description supplied with the antenna. TSAT 2150 Main Unit is only for indoor mount and can therefor not be mounted on a pole. As an option the TSAT 2150 Remote Terminal Main Unit can be mounted inside an outdoor cabinet. The outdoor cabinet is mountable either on the pole or on a wall, sees Figure 2-5. 2.4.2 Wall mount If a wall mount is used, the distance from the wall to the pole must allow the antenna to be rotated sufficiently to point to the satellite position in the geostationary orbit se Figure 2-2. With the 120 cm antenna the distance from the wall to the pole must be 630 mm to allow pointing parallel with the wall. Figure 2-2 Side view of wall mount for antenna, different mounting configurations. Figure 2-3 Wall mount for Antenna, outline dimensions.

The MM1487A is delivered with all the required parts including the Ø76 mm tube. An outline of the ground mount is shown in Figure 2-4 Figure 2-4 shows the antenna mount MM1487A 2.4.4 Antenna Grounding To avoid hazardous voltages to personnel, the Antenna modules should be properly grounded in accordance with IEC 1024-1-1, with a min. 6 mm2 cable. For this purpose ground terminal marked with a standard ground identifier are available at the rear of the main antenna reflector. Installation, Operation and Maintenance Guide, August 2006 Page 12 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 2.4.5 Outdoor Remote Terminal The Remote Terminal Main Unit can be mounted outdoors as an option. The Main Unit is placed inside an outdoor cabinet, see Figure 2-5.The cabinet contains 35 mm DIN Rail for power and modem mounting. It also has a heater mounted to prevent condensation. Figure 2-5 TSAT MUA1612 outdoor Main unit Installation, Operation and Maintenance Guide, August 2006 Page 13 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 2.5 2.5.1 Cable requirements Data cable requirements The electrical interfaces of the HUB Station and Remote Terminal data ports (circuitswitched/async.) comply with the RS-232 standard. The cable environmental specifications must satisfy the local conditions. The maximum cable length according to this standard is 15 meters at 9600 bps. Practical use has shown that this length normally may be exceeded without observable degradation up to 30 meters. However, in noisy environments even distances of a few meters may give unreliable performance. In this case, or for long cable lengths, the signals must be transmitted via short haul modems or data signal converters. For the use of short haul modems, please refer to the short haul modem documentation. The connector pinning for the Main Unit ports are given in section 7. 2.5.2 RF Front End cable requirements TSAT 2150 The RF Front End is connected with the Main Unit with two coaxial cables (cable harness kit CH1493), they have N connector mounted in both ends. The cable specifications depend on the distance between the Main Unit and RF Front End. The cable loss on the Tx signal must be between 6 and 12 dB and between 6 and 18 dB for Rx signal. The maximum cable voltage loss is 0.5 V for DC power supply. The 10 MHz reference oscillator signal is multiplexed onto the coax cable. Normally, coaxial cables have negligible losses at 10 MHz. N connectors are used on both the RF Front End and Main Unit. For long distances, low-loss coaxial cables are required. The cables must satisfy the local outdoor environmental specifications. A list of the loss pr. 10 m for various cables is given in table 2.2. The coaxial cable distributes all signals between RF Front End and Main Unit. For description of signals refer to table 7.3.

Installation, Operation and Maintenance Guide, August 2006 Page 15 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 3.2 Antenna Unit assembly Assemble and mount the antenna according to the description supplied with the antenna. 3.3 3.3.1 Antenna pointing Introduction To point the antenna, the elevation and azimuth angles at the site must be known, see section 0. The procedure described below assumes that a Ku-band TV carrier is available at the same geostationary orbit position as the satellite of interest. If this is not the case, personnel familiar with pointing antennas to satellites must operate a beacon finder or spectrum analyser. Three parts, BUC (Tx unit), LNB (Rx unit) and waveguide with LPF (Low Pass Filter) make up the TSAT2150 RF Front End. The RF Front End are available in several versions, see table 3.1, all combinations are legal. On TSAT2150 HUB Main Unit the Rx L-Band connector can be used in connection with any TSAT2150 RF Front End to monitor the received TV carrier, this connector is an option. Frequency range (GHz) Local oscillator (GHz) Input/Output frequency range (MHz) Tx: 14.00 - 14.50 13.05 Input: 950 – 1450 Rx: 12.25 – 12.75 11.30 Output: 950 – 1450 Rx: 10.95 – 11.70 10.00 Output: 950 – 1450 Rx: 11.70 – 12.20 10.75 Output: 950 – 1450 Table 3.1 RF Front End frequencies for TSAT 2150 The pointing procedure is based on using a "satellite finder", an instrument for monitoring received TV carrier levels in the Ku-band. Normally the TV sound can be monitored, and some models display the TV picture. The signal level is displayed, allowing the antenna to be adjusted to the maximum receive gain position. These instruments normally assume the use of standard LNBs with a local oscillator of 10 GHz. The input frequency range is therefore normally 950 MHz to 1700 MHz. The TSAT RF Front End uses an PLL LNB, these LNBs needs a 10MHz external reference signal. Most instruments used for pointing antennas don’t supply this. It is therefore normally necessary to mount a standard TV reception LNB for the antenna pointing, and mount the TSAT2150 RF Front End after the antenna is adjusted to the correct position. Installation, Operation and Maintenance Guide, August 2006 Page 16 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 3.3.2 Required tools and instruments The procedure below is based on finding a TV carrier at the same geostationary orbit position, and adjusting the antenna bore sight to give a maximum signal level. The antenna will then be at the correct position also for the TSAT 2150 carriers. It is also necessary to adjust the rotational angle of the RF Front End to adjust the cross polar interference level to the specified level. The ETSI specifications state that the polarisation angle should be aligned with an accuracy better than ± 1 degree, corresponding to a cross polar level lower than - 35 dBc (see also section 3.4.2.). The recommended equipment for pointing the antenna is: • Satellite finder, i.e. Kathrine MSK 1 • Compass with accuracy better than 1 degree. Recommendation Silva type: SM360 LA. • Knowledge of true north to magnetic north angle • Map over the antenna site area • Knowledge of TV carriers in the same and adjacent satellite positions • Inclinometer with a bar/rod slightly longer than the antenna diameter, resolution better than 1 degrees degree and accuracy +/- 0.25 degree. Recommendation: Silva type: CM360 % LA. • Low cost standard LNB that can be mounted to the antenna horn wave guide • Recommended tools for adjusting the RF Front End rotation (cross-polar adjustment): Inclinometer with bar/rod suitable for measuring the RF Front End rotation angle Installation, Operation and Maintenance Guide, August 2006 Page 17 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 3.3.3 Antenna pointing procedure 3.3.3.1 Pre-adjustment of antenna Determining the elevation and azimuth of the antenna is described in section 2. The antenna elevation can be adjusted to the approximate position by using the inclinometer and a bar across the main antenna reflector, as indicated in figure 3-2. The correspondence between the main antenna reflector and bore sight angle of the antenna differs slightly, and can be found in the antenna assembly description. lane and antenna bore sight angle. The antenna azimuth angle can be adjusted to the approximate position by using a compass. The magnetic field conditions of the site may influence the compass strongly. If the site is located near large buildings, the compass direction may be completely wrong, with large fluctuations over only a few meters distance. To check this, move the compass a few meters to each side. A map over the site may be used to establish a reference direction. The azimuth angle of interest can than be adjusted by using the compass to rotate the antenna relative to the reference direction. The antenna should now be pointing approximately in the right direction (within a few degrees). Figure 3-2 Antenna elevation pre-adjustment α = angle between main reflector and antenna bore sight γ = inclinometer angle β = site elevation angle Installation, Operation and Maintenance Guide, August 2006 Page 18 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 3.3.3.2 Satellite acquisition Mount the TV reception LNB to the antenna horn. Connect the LNB to the satellite finder instrument, and adjust the satellite finder to monitor an available TV carrier at the satellite position. (Please refer to the manual for the LNB and satellite finder instrument for detailed operating instructions). Rotate the antenna back and forth a few degrees in the azimuth plane, and observe if the TV carrier of interest is received. If no carrier is received, adjust the satellite finder to receive other TV carrier. If the result is still negative, repeat carefully the procedure for pre-adjusting the antenna, or adjust the antenna to point to an adjacent satellite with a known TV carrier, i.e. ASTRA. When a known satellite is found, this position can be used as reference. A marker tape with a degree scale for a 76 mm pole is available, see figure 3-3. This scale can be taped onto the 76 mm pole with the 0 degree marker at a well defined point. The antenna can then be rotated relative to this point to the position of interest. The scale must be taped on the pole in temperature over 10°C. Figure 3-3 Relative degree scale marker for 76 mm pole. This figure is not in true size. When the correct carrier on the correct satellite is found, peak the signal level by adjusting the antenna carefully in both the elevation and azimuth plane several times, since the adjusting one of the planes also slightly effect the direction in the other plane. Fix the antenna bracket in the position giving the maximum signal level. Ensure that the maximum signal level is received also after the antenna bracket has been fixed. Remove the LNB from the antenna horn. The antenna should now be pointing with a maximum gain towards the satellite of interest.

Transmit and receive are mounted in a 90 degrees angle to each other. One example of mounting is shown in Figure 3-4 RF Front End assembly, OMT and filter are delivered with antenna and is only shown here as example. Make sure that there is O-rings between all parts. See the antenna assembly instruction for OMT and feed horn assembly. LNB Filter BUC OMT Figure 3-4 RF Front End assembly Installation, Operation and Maintenance Guide, August 2006 Page 20 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 3.4.2 RF Front End rotation adjustment The satellite transponder operates with linear polarisation, either horizontal (H) or vertical (V). The polarisation must therefore be known when installing the RF Front End. The orientation of the BUC in vertical polarisation for Tx is shown in figure 3-5. Figure 3-5 Orientation of BUC in vertical polarisation for Tx RF Front End rotation adjustment for minimising cross-polar radiation level. The RF Front End must be set at the correct rotation angle with an accuracy within 1 degree, corresponding to a cross polar level below -35 dBc. The antenna is normally delivered with a fixed mount. In this case, the angle is a function of the antenna site position and the satellite position. figure 3-6 displays graphs for the cross-polar rotation angle with reference to the gravitation vector, as a function of the azimuth angle, with the elevation as the parameter. The same data is tabulated in table 3.2. Normally, the horizontal polarisation direction is parallel to the geostationary orbit, and vertical polarisation is then perpendicular to the geostationary orbit. This orientation is assumed in figure 3-6 and table 3.2. Some satellites have a polarisation offset that also must be taken into account. Before a new satellite is taken into use, the satellite operator should confirm this information.

The RF Front End rotation is adjusted as shown in figure 3-5 by laying an inclinometer across the RF Front End, and adjusting the rotation angle according to table 3.2. Linear interpolation can be used for values not tabulated. Recommended inclinometer Silva type: CM360 % LA. Follow this procedure after you have found the correct satellite. See section 3.3 Use 1. table 3.2 to determine the RF Front End angle. Remember to take into account any offset angle given by satellite operator. 2. Adjust the antenna to set the RF Front End close to horizontal position. 3. Use the inclinometer and adjust the RF Front End to the angle from point 1. Use a knife to put a thin mark on the feed horn and feed horn-mounting bracket. 4. Adjust the antenna to the correct elevation angle. Use another LNB if necessary. 5. If the RF Front End have been removed when doing point 4, adjust the RF Front End to the mark in point 3. 6. Tightened the feed horn to the bracket.

Without any brackets it can be placed on a table. Optionally TSAT AS can deliver brackets for wall or 19” mount. The standard Main Unit must be mounted indoors, but it is possible to get an outdoor option. 3.6 Reference Oscillator Unit Mounting The Reference Oscillator Unit (RO1483) may be mounted to a wall, on a table or shelf or in a 19” rack. The unit is shown in figure 3-1. 3.7 Supervisory Terminal Installation The Supervisory Terminal is a standard Windows PC, and is normally powered by 220 VAC. The Supervisory Terminal program is normally pre-installed. If this is not the case, please refer to the "Supervisory Terminal User Guide" for installation instructions. 3.8 HUB Station Modules Interconnection on TSAT 2150 The interconnection between the RF Front End, Main Unit, Reference Oscillator Unit and Supervisory Terminal is shown in figure 3-7. All DSUB connectors should be secured with the connector housing screws. The SMA connectors should be tightened with a SMA momentum tool (i.e. Suhner 74Z-0-0-79) with a recommended momentum of 0,45 Nm.

Offset Antenna, shown as example • 2. RF Front End Assembly (RFA1602) • 3. Main Unit Assembly (MUA1532) • 4. Cable Kit Assemble CKA1489 Other required units are: • Antenna mounting structure. • Power supply • Coaxial cables between Main Unit and RF Front End When the instructions in this section is completed, the TSAT 2150 Remote Terminal should be ready for being set into operation as described in section 6. 1 4 5 2 3 Figure 4-1 TSAT 2150 Remote Terminal modules Installation, Operation and Maintenance Guide, August 2006 Page 25 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 4.3 Antenna Unit assembly Assemble and mount the antenna according to the description supplied with the antenna. 4.4 Antenna Unit mounting The antenna-mounting pole must satisfy the antenna site requirements discussed in section 2. If a wall mount is used, we recommend the MM1484. 4.5 Antenna pointing The antenna pointing instructions are identical to the instructions given for the HUB antenna in section 3.3. On TSAT2150 RT Main Unit the Rx L-Band connector can be used in connection with any TSAT2150 RF Front End to monitor the received TV carrier, this connector is an option. 4.6 RF Front End Mounting The RF Front End mounting instructions are identical to the instructions given for the HUB Station in section 3.4. 4.7 Remote Terminal modules interconnection TSAT 2150 The modules are connected with cables as indicated in figure 4-2. The cable requirements are described in section 2, and the connector pinning is described in section 7. All DSUB connectors should be secured with the connector housing screws.

Installation, Operation and Maintenance Guide, August 2006 Page 26 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 5 5.1 HUB Station Operation Pre-operational requirements Before starting up the HUB Station, the procedure described in section 3 must be completed, including interconnecting all the modules as described. It is important that the satellite control centre is contacted for line-up test, in some cases separate test frequencies can be supplied. 5.2 Main Unit configuration The HUB Main Unit must be configured with the correct parameters, including operating frequencies and output power, using the Configuration programs or the NMS SW. A detailed description of configuring the HUB Station Main Unit is given in document "TSAT 2150 Configuration and Diagnostics". This initial configuration of the HUB Main Unit must be done with the Tx coaxial cable disconnected. 5.3 Supervisory Terminal configuration Start the Supervisory Terminal program, and confirm that the Supervisory Terminal COM port to the HUB CCU is configured correctly (standard configuration: COM1, 38400, n, 8, 1). 5.4 HUB Station power-up The HUB Reference Oscillator Unit requires 15 minutes warm-up before the reference oscillator frequency is stabilised. The Reference Oscillator Unit will not supply any reference signal before after 15 minutes. An LED on the Reference Oscillator will indicate when a signal is supplied from the reference oscillator. Observe the HUB CCU reset message on the Supervisory Terminal, indicating that the CCU has been reset at power-up, and confirming a connection between the HUB CCU in the Main Unit, and the Supervisory Terminal. (If no such message is seen, se section 7). Within 10 minutes, the following message should be observed: "HUB Carrier found" The HUB is now ready to receive a Remote Terminal, se section 5 for Remote Terminal Operation. When a Remote Terminal is operational the following messages should be observed: “RT Carrier found" "Link is up to RT1" (or any other active Remote Terminal) The network is then in normal operation, and capable of transmitting application data. If no RT's are installed, only the "HUB Carrier found" message will be displayed, and the HUB will eventually reset itself after a time-out in acquiring the inbound carrier from an RT. 5.5 Circuit-switched protocol operation The HUB Station circuit-switched application port(s) are serial async. PC communication ports on the Supervisory Terminal. One port on The HUB Main Unit can be configured to be a leased line port or a Multidrop port independent of the port in the Supervisory Terminal. The standard configuration of the Supervisory Terminal has 4 serial ports: • One port for connection to the HUB Main Unit (normally PC port COM2) • Two application ports (normally COM3 and COM4). • One port free for another application or remote control via modem (normally COM1). The Supervisory Terminal application port configuration must match the application port configuration of the connected application (ref. Supervisory Terminal User Guide for configuring the PC ports). When the Supervisory Terminal port(s) are correctly configured, and the application is started, application data can be monitored in the Supervisory Terminal, confirming normal operation. Installation, Operation and Maintenance Guide, August 2006 Page 27 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 5.6 5.6.1 Supervisory Terminal Operation Introduction This section gives general guidelines of how the Supervisory Terminal functionality may be used to manage the TSAT network. The detailed procedure of the Supervisory Terminal functions is given in the "Supervisory Terminal User Guide". 5.6.2 Network Status monitoring The status and network management windows of the Supervisory Terminal monitor the status of the network. The status messages may be logged to a file. The daily routines for the log file management strongly depend on the user requirements and the property of the application, i.e. if the application itself gives a warning if an error occurs in the TSAT network. It is therefore difficult to give general guidelines in this matter. A suggested procedure may be to open a log file once a week and store the log files for some months. 5.6.3 Logging of statistical data Selecting the automatic polling of "All active links", and opening a log file, will result in the logging of the Eb/N0 ratio on all active links with the specified time interval. By monitoring the Eb/N0, one may observe changes in Eb/N0 ratio that may suggest the need for a site inspection, or indicate a potential problem with a RT at an early stage. Again it is the user requirements that determines how and if this function should be used. A suggested guideline is to set the polling interval to once per day, and inspect the log file once per week. 5.7 Adding new Remote Terminals If the network is expanded with Remote Terminals, the new Remote Terminals must be defined in the Supervisory Terminal. The HUB CCU must also be configured with a sufficiently large parameter for the number of Remote Terminals in the network. When the Remote Terminal is installed, it will automatically log on to the network after power-up. If the RT is not defined in the Supervisory Terminal or HUB CCU, an error message will be displayed when the RT tries to log on to the network. 5.8 Removing Remote Terminals from the network If a Remote Terminal is turned off, the HUB CCU will recognise that the Remote Terminal has stopped to respond, and sends a "Link is Down" message to the Supervisory Terminal. The time required to recognise a Remote Terminal shutdown depends on the network traffic and network size. 5.9 HUB Station Diagnostics The diagnostics program includes diagnostic facilities for verifying the performance, including: • Received Eb/No (signal to noise) condition monitoring • Confirmation of normal network operation • Hardware status information The TSAT diagnostics tool is described in the document "TSAT 2000 Configuration and Diagnostics". Installation, Operation and Maintenance Guide, August 2006 Page 28 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 6 Remote Terminal Operation 6.1 Introduction Before being set into operation, the procedure given in section 4 must be completed, the power supply must be installed, and the Remote Terminal must be correctly configured in agreement with the application equipment configuration. Connection and disconnection of the connectors (POWER and RF Front End ports) must only take place with the power supply turned off. In some cases the satellite control centre must be contacted to do line-up tests before powering the Remote Terminal. 6.2 Remote Terminal Configuration The Remote Terminal is configured by connecting one of the async ports to a PC serial communication port, and running the "TSAT 2000 Configuration and Diagnostics" program. The Remote Terminal async port must be set to "Service port" mode. A detailed description of configuring the Remote Terminal is given in "TSAT 2000 Configuration and Diagnostics". 6.3 6.3.1 Application port operation Async. ports Connect the Remote Terminal COM port(s) to the application equipment (COM1, COM2 or X.25). Confirm that the application equipment operates normally, communicating with the HUB application equipment. If so, the async application ports are in normal operation. If problems arise in operating the application ports, please refer to the section "Trouble-shooting". As described in section 9, the Remote Terminal operation can also be confirmed from a PC with TSAT diagnostics software, independent of any application equipment. 6.4 Remote Terminal Diagnostics The diagnostics program includes diagnostic facilities for verifying the Remote Terminal performance, including: • Received Eb/No (signal to noise) condition monitoring • Confirmation of normal network operation • Hardware status information Installation, Operation and Maintenance Guide, August 2006 Page 29 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 7 7.1 Interface specifications TSAT 2150 In this section, the external electrical interfaces of the RF Front End, HUB and Remote Terminal Main Unit, Reference Oscillator Unit and Supervisory Terminal are described.

The procedure of upgrading or replacing Main Unit software or hardware is also described. Be sure that the unit is powered off before any maintenance is performed. Normally, a minimum of maintenance is required. When problems arise, the normal approach will be to try to identify which unit is faulty, and return this unit for repair. Hardware maintenance or upgrades may comprise of changing SW modules, or replacing a faulty PCB. The RF Front End does not contain any modules that can be replaced or upgraded in the field. Unauthorised personnel must not open the RF Front End. This will result in violating any warranty or guarantee conditions for this unit. 8.2 Normal maintenance The HUB Station does not require much maintenance under normal conditions, except log file management of the Supervisory Terminal. Adjustment of the HUB reference oscillator is necessary once a year. It is also recommended that the site is inspected once a year and that the points listed below are checked. Antenna Visual inspection of: • Protective feed horn cap • Antenna mounting bracket • Support structure stability • Grounding cable RF Front End Visual inspection of: • Feed horn mount • Cables to Main Unit Main Unit Visual inspection of: • Main Unit mounting screws • Main Unit cables and connectors Reference Oscillator Unit Visual inspection of: • Adjustment of the reference oscillator • Visual inspection of cables Power supply Visual inspection of: • Power supply connection to mains or battery system • Power supply connection to Main Unit cable Installation, Operation and Maintenance Guide, August 2006 Page 32 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 8.3 8.3.1 Main Unit service/upgrade TSAT 2150 Introduction This section describes how to change configuration and upgrade software. Removing plastic frame in rear opens the Main Unit, removing the 4 screws and pull out the Main Board. The Main Unit contains a Main board, a DSP board and a Tx board. The Main Unit also contains three fuses, one fuse for Main Board 3A, one fuse for Tx board 2A and one fuse for Rx 1A. 8.3.2 Hardware configuration See TSAT 2150 Hardware Configuration Guide for configuration of Main Unit and jumper settings. 8.3.3 Software upgrade The Main Unit can contain five Flash modules: • CCU software bank A high and low and bank B high and low. • DSP software. To upgrade DSP SW the flash must be replaced. The CCU SW can be upgraded when a unit is directly connected to a PC running NMS SW, a Remote Terminal can be upgraded via the satellite link. See TSAT 2150 Hardware Configuration Guide for location of EPROM’s. 8.4 HUB Reference Oscillator Unit service Frequency Adjustment If frequency adjustment should be necessary, remove the large screw on the back plate. Connect a frequency counter - 50 Ohm input to the MONITOR connector. Use a 2 x 0.5 mm screwdriver and adjust the reference oscillator by turning the screw. The specification of the frequency counter must be better than 1x10-8. Check the frequency after one hour with power, and readjust if necessary. 8.5 Supervisory Terminal service/maintenance The Supervisory Terminal PC normally requires no maintenance, other than management of log files as described under "Supervisory Terminal Operation". If a failure occurs, contact PC service personnel, or the local service organisation. Installation, Operation and Maintenance Guide, August 2006 Page 33 of 42 TSAT 2150 - Telemetry and data transfer via SATellite 9 9.1 Trouble-shooting Supervisory Terminal Normal operation When the network is operating normally, the "TSAT Network Configuration" window shall indicate the actual status of all defined links: • Green icon and "Link is UP" if the RT is on-line • Red icon and "Link is DOWN" if the RT is off-line Unexpected situations may arise. In the following, a short description of trouble-shooting procedures is given. The link is UP, but should have been down. The link protocol shall be capable of handling collisions and retransmissions. It will therefore take some minutes before a link falls down until the HUB CCU in the Main Unit changes the status of the link, and sends a message to the Supervisory Terminal. If it seems to take too long, polling the HUB CCU for the link status can check the communication link to the HUB CCU. If a message is received, the communication is OK. If not, check the communication link to the HUB CCU. Check-list for communication link to CCU Cable and connectors HUB Main Unit powered Communication settings OK: HUB CCU port number and communication parameters normally (38400,n,8,1) The link is down, but should have been UP After reset, it might take up to 5 minutes before the links are opened, due to frequency acquisition and modem synchronisation. Make sure a message is returned when polling the HUB Main Unit for link status. If not, refer to the check list above for communication with the HUB CCU. The HUB CCU in the Main Unit controls the link status. It can be opened and closed by the operator at the Supervisory Terminal with the commands "Open Link" and "Close Link". If the operator at the Supervisory Terminal closes the link, the operator must also open it again before the link status can change, or the HUB Main Unit must be reset. Link status is UP, but is the link really up? To confirm that a link is really up, select the "Poll RT Statistics" command, and select the RT of interest. If the link is up, a message will be received in the status message window, confirming the reception of a statistics packet from the RT. If the link has recently failed, the HUB CCU will in a short time time-out the RT poll request due to the lack of answer, and report a change of the link status to down. This test does however not check the status of the application ports. Are the application ports operating as normal? To check the operation of the application ports at the RT, it is necessary to start a connected application on the RT side, or poll a connected application from the HUB side. The flow of application data can be observed (in hex format) at the Supervisory Terminal by opening the application data window.
