Appearance, basic functions and characteristics of G-50A (1) Appearance and functionality This controller has higher functionality than any previous centralized controllers, and this product is the first in the industry to support the web. One G-50A unit can control and monitor up to 50 indoor units. This controller can be controlled and operated by browser software (Internet Explorer ver. 5 or above) from a PC connected via LAN or telephone lines. Other than the basic operation of the packaged air conditioners, it can support various functions required for air conditioning controlling such as “Annual schedule operation” “Air-conditioning energy charging” “Energy-saving operation”, by adding optional functions. (2) Basic Functions Appearance G-50A unit Major functions Operation and setting of the air conditions Monitor air conditioners Scheduling function External input/ output is possible ON/OFF Operation mode change Temperature setting Air velocity change Airflow direction setting Operation status (ON/OFF) Operation mode monitor Temperature monitor Failure monitor Air velocity change Airflow direction change Weekly schedule operation possible ON/OFF and abnormal conditions can be output to outside; emergency stop and ON/OFF can be input from outside. (3) Characteristics Software for PC monitor/control and necessity of license certification Browser software License (PC software) certification Internet Explorer Monitor and control Ver.5 ~ Necessary by PC TG2000A (optional product) Internet Explorer Annual scheduling Ver.5 ~ Necessary function TG2000A (optional product) Air-conditioning energy TG2000A Necessary charging (optional product) Energy saving TG2000A Necessary operation function (optional product) 1) Besides the monitor/control from the G-50A unit, remote monitor/ control from a PC is also possible. (This is an optional function and requires input of a separate license number.) * License certification : License registration is required to use the This has a web server function, and the operation control can be optional function ( to be charged). made from a PC connected through LAN or public phone lines. Using a PC browser (Internet Explorer Ver.5 or above), you can easily build a centralized monitor system for air conditioners. You can confirm the operation status and make sure the power is off Remote control from Web browser Air conditioning without walking to the remote controller location or patrolling to the far management away sites. This means you can improve the efficiency of air conditioning control work and save energy through a thorough operation control. 2) You can control up to 2000 indoor units using special integrated software. (This is an optional function and requires input of a separate license number.) Public circuit Router If you use G-50A special integrated software (PAC-TG2000A), you can consolidate data from all the G-50A units, and control the operation of up Watt-hour City Multi meter to 2000 units from a PC. Furthermore, floor plans can be drawn, and operation status can be indicated for each floor or for each tenant. 3) Annual schedule management is possible. (This is an optional function and requires input of a separate license number.) The standard functions include a weekly schedule function, but you can also register annual schedule on a PC as an option, and you can have 7 different patterns for days of the week, plus 5 patterns of schedule can be set on 50 special days per year. By having thorough control, you can achieve a tremendous energy-saving, unmanned operation on a day-to-day basis, and automatic operation of air conditioning. * Once a license for annual schedule is registered, G-50A unit cannot set a schedule. It has to be set and registered only on PC. 4) Electric power apportionment information can be obtained to calculate air conditioning charge for each area. (Optional function. A separate license number has to be input.) Using electric power apportionment function (optional), you can enter the electric power apportionment data for each indoor unit into a PC in CSV format. By manually inputting the total power usage, customer can have a simplified power usage count for each tenant. * The air conditioning cost calculation method use by this integrated centralized control software TG-2000A is the Mitsubishi proprietary general electric power apportioning method. Depending on each country’s laws and regulations, etc., there may be cases these measured charges cannot be used for certificate of transaction. 5) With the addition of the designated sequencer and electric energy count software, air conditioning charge can be automatically calculated. (This is an optional function and requires input of a separate license number.) In addition to the system described above, if you add a sequencer (MESLEC-Q series) and power usage count software (optional), you can have power usage reading from the watt hour meter or electric power count by PC direct connect (RS-485WHM). Based on that information and G-50A integrated software (TG-2000A), you can calculate the power usage count per tenant. * The air conditioning cost calculation method use by this integrated centralized control software TG-2000A is the Mitsubishi proprietary general electric power apportioning method. Depending on each country’s laws and regulations, etc., there may be cases these measured charges cannot be used for certificate of transaction. 6) Energy-saving operation mode will help reduce the power consumption without harming the comfort. (This is an optional function and requires input of a separate license number.) Energy-saving operation mode (optional) will enable rotated fan operation and heating/cooling power save operation. Energy can be saved in a way to meet the customer’s demand. * With this function, air in-take temperature and room temperature setting will be considered, and the room temperature setting will be shifted to a higher side during cooling period and to a lower side during heating period at a fixed time interval. For instance, if the air intake temperature is set at 24°C and the room temperature setting is 22°C for air conditioning, the room temperature setting will be altered to 24°C. If the air intake temperature is 28°C and room temperature setting is 22°C, there will be no change. 7) In case of abnormality, a mail will be sent to cell phones or PCs. (This is an optional function and requires input of a separate license number.) If there is something wrong with the air conditioning unit, the abnormality will be notified to the designated mail address. You can be notified of the abnormality wherever you are, and take necessary actions to recover the system quickly. -2- 2. Examples of G-50A utilization (1) Make the control work more efficient by remote control and operation. 1) While you are at your desk doing paper work, you can monitor and control air conditioners from a PC on your desk. 2) When you leave the office for the day, you don’t have to check every remote controller to make sure the power is off. ON/OFF operation can be made collectively from a PC. 3) You can monitor and control air conditioners in remote buildings (via LAN or public phone lines). 4) If you take a lap top PC and PHS with you, you can monitor and control the system away from your office. 5) You can prohibit ON/OFF operation, temperature setting change, and operation mode change by local remote controllers. (2) Energy saving is possible through annually schedule operation 1) By adding optional functions, you can have extended weekly schedule operation and annual schedule operation. (You have to specially register the setting in a PC.) 2) Besides ON/OFF operation, you can schedule operation mode and temperature settings by the unit of minutes. 3) Prohibition of ON/OFF operation, temperature setting change, and operation mode change can be set to the minute so that you can control temperature settings well and never forget to turn off the switch. Example 1: ON/OFF switch can be prohibited during night, making the air conditioning unit inoperable during night. Example 2: Fix the room temperature at 25°C for air conditioning during the intermediate season. Example 3: Energy-saving operation is possible by making the unit inoperable during lunch break or setting the room temperature on a higher side and fixing it. 4) Shops and stores can have air conditioning operation adjusted by pre-setting the room temperature depending on the estimated turnout of visitors for the day. 5) The day’s schedule can be adjusted each day, and air-conditioning in a meeting room can start /stop at a pre-set time.

Extended weekly/annual schedule example G-50A (G-50A provides a billing system in each building) Maintenance Company The optional software can store electricity billing data calculated for each tenant. All I have to do is retrieve the data into spreadsheet software and process into bills. It is very convenient and efficient. (3) Air conditioning charge data can be freely processed on a PC. 1) Air conditioning charge can be calculated as an option. 2) Air conditioning charge data can be edited and processed on a PC. 3) If you build a PC network, you can get the electric power apportioned charge data from a remote location and the transaction can be made without human intervention such as transferring or posting data. 4) If the electric power apportionment function is used, you can confirm the integrated running time of each air conditioning unit. Bill G-50A (4) With the existing air conditioners, energy saving can be accomplished. G-50A G-50A Case: 1 Remote controllers and wires can be destructive to interior design. 1) Energy saving operation will enable energy saving easily. (5) By eliminating the use of local remote controllers, the interior aesthetics will be enhanced. 1) If you are bothered by the design of a remote controller or wiring in the room, you can get rid of them. 2) In a lobby or a place with high traffic, or if you don’t want students or patients to handle a remote controller in a classroom or in a hospital, you can eliminate use of a local remote controller. (6) Various interlock operation is possible using a sequencer. 1) With an interlock to “key lock” and “human thermal sensor” as an energy-saving measure, you can stop the operation of an air conditioning unit when the room is locked or there is nobody inside. 2) Detecting the upper limit and lower limit of the local humidity sensor or temperature sensor, cooling/heating and dry operation can be activated or stopped. (7) Notice of error code via mail at malfunction 1) In case of a machine trouble, the unit number with the faulty operation and the code number for the trouble will be sent by email. Since the type of trouble can be promptly communicated and the spare parts can be arranged in advance, a swift recovery will be possible. In case of “Mr. Slim”, the code will be displayed on G-50A in 4 digits. Basically they are same as Building Multi, but there is one code unique to Mr. Slim, that is “68**” for a Mr. Slim indoor/outdoor unit communication error. Case: 2 Remote controllers need to be avoided or concealed in high-traffic areas such as building lobbies. G-50A Shop G-50A Office Case: 3 Remote controller groupings and locations are subject to frequent change in locations such as tenant buildings I can check the nature of troubles without asking customers. It is convenient. G-50A Coffee Shop G-50A • Air conditioners of different outlets are constantly monitored. Reports are provided to the designated e-mail addresses in the event of troubles. • Quick restoration is possible thanks to the ability to understand the nature of troubles early. -3- 3.

Grouping information and interlock setting information will not be lost even when the power information is off. Trouble history It would not be lost even when the power is off. Timer operation The schedule information for each group will not be lost even when the power is off. Even when the power is off, the time clock will be run by the internal condenser for about Current time one week. (Recharging the internal condenser will take about one day. Battery replacement is not necessary.) -5- 4. Special considerations about the use of G-50A, due to its difference from conventional models, and the concept of the upper class and lower class (1) Special considerations about the use of G-50A, due to its difference from conventional models 1) A group of indoor units cannot be controlled by more than two G-50A units. You cannot have multiple connections of G-50A within the same group. → If you want to have 2 separate centralized control within the same group, use one G-50A and one system remote controller, or something equivalent. (The reason is described below in the concept of upper class and lower class.) 2) G-50A cannot be used together with the system controller like MJ-300 that are higher in class than G-50A. (2) The concept of upper class and lower class pertaining to G-50A *Upper class system controller and lower class system controller This unit (G-50A) always functions as an upper class system controller. controller. It can not be treated as a lower class system • Upper class system controller (upper class SC) A system controller that encompasses the control scope of all other system controllers is called “upper class system controller”. Also, if there is only one controller in the entire system, that controller becomes the upper class system controller. Only the upper class system controller needs to have a group setting and interlocking operation setting. • Lower class system controller (lower class SC) A controller whose entire control area is controlled by an upper class system controller is called a lower class system controller. Control scope of upper class SC Control scope of lower class SC Group Group Group This unit is for upper class SC use only. It cannot be used as a lower class SC and controlled by upper class SC (gateway and others). The following group settings cannot be made. • A group outside the control of the upper class system controller is controlled by a lower class controller. Upper class system controller Group Lower class system controller Group Group • Two or more system controllers control the same group of units. Upper class system controller 1 Group Upper class system controller 2 Group Group Therefore, G-50A always has to be an upper class system controller. G-50A can never be used as a lower class system controller. -6- 5.

This shield for M-NET centralized system transmission lines should be grounded at a single point through the transmission line power supply unit. Indoor/outdoor transmission lines should be grounded for each outdoor unit system. M-NET outdoor unit centralized control switch (SW2-1) should be always “ON”. (2) Address setting for equipment Indoor unit Address setting method Address The lowest number should be given to the indoor unit functioning as the parent unit within the same group. Give the serial numbers to the indoor units in the same group. 1 ~ 50 Outdoor unit Take the lowest number of indoor unit address within the same refrigerant system and add 50 to it. Outdoor auxiliary unit (BC controller, etc.) Take the address of the outdoor unit within the refrigerant system and add 1 to it. Lossnay After all the indoor units are given the address, choose any number as address. M-NET remote controller Take the lowest number of indoor unit (parent unit) address in the same group and add 100 to it. However, in case of a subordinate remote controller, add 150 to it. 101 ~ 200 MA type remote controller Address setting is not necessary. In case of 2 remote controller operation, however, main/subordinate switching setting is necessary. − K-control indoor unit After all the M-NET indoor units (including Lossnay) are assigned a number, the next number should be set for K-control indoor units. 1 ~ 50 K-control remote controller Take the lowest number given to the K-control indoor unit (parent unit) in the same group, and use the same address. K-transmission converter The lowest number of the K-control indoor unit + 200 should be used as address. -7- 51 ~ 100 52 ~ 100 1 ~ 50 1 ~ 50 201 ~ 250 (3) G-50A power supply 1) In case a transmission line power supply unit is used.

In such a case, the controller should be connected to indoor/outdoor system transmission lines. PAC-SC50KUA 2 sets • When only one G-50A is connected. Up to 3 other system controllers can be connected to the centralized control system transmission lines. • When 2 of G-50A are connected. (When the system of 50 or less indoor units is divided into two groups, and each is controlled by G-50A.) Only one other system controller can be connected to the centralized control system transmission lines. 2) Points to notice when connecting to indoor/outdoor transmission lines • The system controllers that can be connected to indoor/outdoor transmission lines are: G-50A, MJ-103MTR-A, PAC-YT34STA, PAC-SF44SRA, PAC-SC30GRA. However, the outdoor unit City Multi S cannot have a system controller connected to indoor/outdoor transmission lines. Also, in case connecting a system controller to indoor/outdoor transmission lines, the system controller becomes unable to control once the outdoor unit power supply is shut off. Please give enough precaution to that point. In case you use the electric power apportioned charging ("Air Con Electricity Charge") function, as an option to the centralized controller G-50A, do not connect G-50A to indoor/outdoor transmission lines. • Up to 3 system controllers can be connected within the same refrigerant system, and only one G-50A unit can be one of those 3. In that case, the number of connectable indoor units will be 4 less. If other system controllers are used, the number of maximum connection per group will be 2 less per system controller. -8- 6.

Group Block for operation Block for charging (7) Function of Air-conditioning energy charging 1) In the case that there is a group not being set as a block for charging, electric power in the group is not reflected on air-conditioning charge. Set up both the block for operation and block for charging for the groups which Air-conditioning energy charging is necessary. 2) The Air-conditioning energy charging is calculated in a unit of blocks. Even if LOSSNAY with the humidifier, Free plan LOSSNAY, A-control equipment, and K-control equipment are included in the block for accounting, they are not taken into account in the ratio calculation. 3) The Air-conditioning energy charging (Electric power input by hand) is not subject to Lossnay with the humidifier, Free plan Lossnay, A-control equipment, and K-control equipment. 4) For indoor units with M-NET control system a part of the old models are not provided for the function of electric power-apportioned charging. (8) Instructions for the use of the Air-conditioning energy charging The air conditioning cost calculation method use by this integrated centralized control software TG-2000A is the Mitsubishi proprietary general electric power apportioning method. Depending on each country’s laws and regulations, etc., there may be cases these measured charges cannot be used for certificate of transaction. Before starting use, the building owner and building tenant should bind an agreement or contract indicating that the air conditioning charge are part of the usage fees with an independent contract indicating “The air conditioning charge are collected with an apportioning method that considers the air conditioner’s operation state instead of charges according to the measured power rate (including during emergency operation when a failure occurs)”. (9) How to deal with the Air-conditioning energy charging at the time of failures in the PC The power rate for air-conditioning found by means of the function of the Air-conditioning energy charging is based on the data of the operation amount of the indoor units. In the case that the data fail to be collected due to some kind or another reason, irregular treatment is to be employed. The irregular treatment may require "the maintenance of the charging data", depending on the description of the irregular treatment. Prospective failures are shown in the following table. - 24 - 1) Assumed cases and recovery method (For without WHM connection proportionally divided power charge (manual input of the electric amount)) Assumed case Air conditioning energy monitoring screen Charging data status PC failure (HDD failure) PC failure G-50A communication error (Display impossible) Charging data destroyed Red characters (abnormal) G50A main unit failure Black characters (normal) Forwarded to next day and apportioned to recovery day (Collected for several days and apportioned) Apportioned, but data is not correct (Interval : Error day ~ recovery data) System information setting error Black characters (normal) Black characters (normal) Correction method Operation amount data monitor + remedial apportioning *1 Apportioned based on set information No repair is required *2 Charging data maintenance Charging data maintenance *1 To repair, the operation amount during the time to be repaired is monitored, and the remedial apportioning function is used. *2 When a forwarding that extends past the settlement-of-accounts day occurs, it is recommended to correct it in the "Charge data maintenance" screen. It is unnecessary to perform this procedure when there is an agreement that allows the charge to be collected, even if the forwarded settlement occurs. Note : • If there are two or more assumed cases, make overall judgment. • When forwarding of apportionment spans the settlement-of-accounts day, the forwarded portion is added to the next month. When you want to separate this month's portion and next month's portion, divide the proportion division parameter forwarded and collected by "Charge data maintenance" screen by the number of days in next month and this month. • The charge data status is irregularly processed according to the case which occurred. 2) Outline of the maintenance of charging data (Refer to ‘The maintenance of the charging data’ in the instruction manual of the integrated software TG-2000A for details.) Outline The maintenance of charging data Change and correct the parameterized data for apportion to be corrected for each indoor unit and for each day. After completing the data correction perform the Air-conditioning energy charging again to figure out power rate for air conditioning. 12.

The basic rate is constant every month. b) Electric charge of air-conditioner This is a rate being figured out based on the apportioned calculation of actually consumed electric power by block. Both settling day calculation and maturity-designated time calculation are available. * Settling day calculation: Electric charge of air-conditioner for a period of one month counting from a registered settling day is calculated. The rate is made up and figured out between around 4:00 and 8:00 on the following day of the settling day. (While making up the rate, the PC may become slow to response.) * Maturity-designated time calculation: Electric charge of air-conditioner for a desirable arbitrary period for 61 days counting from the previous day is calculated. c) Electric charge of air-conditioner by time frame Electric charge of air-conditioner for a period of one day is calculated apportioned by two time frames (*). Time frame section can be set up by a day of the week. Also, 5 patterns of time frame section in a year can be set up to 50 days. The time frame divided in 5 sections is under development (Refer to the development separately) Use example: In the case that power rate for air-conditioning loaded between 9:00 and 18:00 is collected together with tenant fee, and that of air-conditioner used between 18:00 and 9:00 in the following morning during overtime duties is desired to be collected according as the use situation, do as follows. Split the time frame into two parts of "9:00 to 18:00" and "18:00 to 9:00 in the following morning, set up a price of zero as a rate for the former and a power unit rate for 18:00 to 9:00 "in the following morning for the latter. d) Seasonal rate The rate can be set to the summer seasonal rate and normal rate separately. e) Weekly rate Setting up power unit rate by a day of the week is also possible. 5) Scheme of power rate calculation a) Power rate for air-conditioning (settle up) (A) Basic rate + (B) electric charge of air conditioner (A) Basic rate : Set up and registered basic rate by billing block (tenant) to be charged (B) Electric charge of air conditioner : It is figured out by making an apportioned calculation of electric energy consumed for air conditioning according to the running status of the air-conditioners, and then by multiplying a unit rate by electric energy after finding the electric energy consumed by each tenant. Apportioned calculation of electric power used by indoor unit Rated power consumption of indoor unit x Accumulated working hours of fan Electric energy used by the indoor unit is found based on the electric energy measured by the watt-hour meter with the sum of the above electric energy (parameter value) and its proportion. Apportioned calculation of electric power used by outdoor unit Electric power used by the indoor unit is divided into standby electric power and other electric power. Standby electric power * → Apportioned calculation by the proportion of indoor unit capacity → Indoor unit capacity x Proportional division by the proportion of capacity control level Other electric power Electric power used by the outdoor unit is found based on the electric power measured by the watt-hour meter with the sum of the above electric power (parameter value) and its proportion. * The standby electric power can be selected from the following three kinds of calculation methods. (1) Apportioned calculation by the proportion of indoor unit capacity in the same refrigerant system (2) Without apportion calculation by electric power as outdoor unit standby electric power (3) Without taking standby electric power into account (0), apportioned calculation by other electric power only The electric power is calculated in a unit of blocks. Even if Lossnay, A-control model, and K-control model are included in the system, electric power for each of these models is not calculated respectively, and it is figured out by a proportional ratio of M-control model. - 29 - System Example of Watt Hour Meter (WHM) - PLC under of Air-Conditioning Energy Charging (Power Pulse Count) Installation side of Air conditioner/WHM When centralized controller G-50A exceeds 4 sets, use HUB with 8 branches or more.

Outline of Energy Saving Control * The specification may be changed as this system is under development. (1) Energy saving control The energy saving control includes the items listed on Table 9-2, and they can be set from the integrated software for each block freely. After setting, G-50A conducts energy saving control on to the air conditioning group within the operation block in a unit of 3 1 (3/6/9/15/30 minutes) within a 30 minutes not allowing overlapping the control time. 2 In consideration of comfort, it can be set not to apply the set energy saving control to the block of which temperature difference between the set and inlet temperature exceeds the temperature difference freely set (3°C ~ 9°C).

Stopping outdoor unit • Transmits "STOP" at control start time and returns to the original start/stop state at control finish. • When the operation was made from local remote controller, browser, G-50A unit or schedule during stopping control, and the state at control finish was not stopping, it does not return to the sate before the control. The maximum value of outdoor unit operating capacity can be controlled to 60%/70%/80% /90% (in 10% unit). The control time may be overlapped depending on the group numbers inside block and control time. Energy saving control is applied at the levels 1~4 regardless of the temperature difference. Controllable only for City Multi air conditioners. (Do not set to Multi-S.)

(If (2) Peak cut control Connecting the watt-hour meter (PLC) allows conducting the energy saving control of Table 9-2 divided into 5 levels (Level 0 ~ Level 4) by estimating the power consumption for 30 minutes. Meantime, the control level is judged with an interval of 1 minute, and the control of higher level is applied in accordance with the measured power consumption for the past 30 minutes and estimated value. - 34 - How to obtain the estimated value : Estimated value (kW) = Power consumption in the past 5 minutes (kWh) x 6 (Power consumption for 30 minutes) x 2 (kWh→kW <30 minutes> converted) . . . . . . (1) In Figure 9-5 for example, it is assumed that the control at the energy saving Level 1 is being conducted in accordance with [Power consumption for the past 30 minutes]. In this occasion, the estimated value after 30 minutes is calculated from [Power consumption for the past 5 minutes] by Equation (1), it reaches the region of energy saving Level 2. In this case, the energy saving control set at the energy saving control Level 2 will be carried out. By making the energy saving ineffective temperature difference effective, under the control of Level 0, when the temperature difference between the set and inlet temperature is exceeding 3°C ~ 9°C (able to set in a unit of 1°C), it is possible not to allow conducting the energy saving control set at Level 0 in consideration of comfort.

For 100BASE-T there is category 5 only. 4) Recommendation and instructions on G-50A a) Category 10BASE-T is recommended for cable for LAN As a system mixing with optical cable 100BASE-TX may be used, category 5 is recommended judging from availability. b) On specifications of the hub There are several kinds of hubs such as 10BASE-T, 100BASE-TX (automatic switching type), exclusive for 10BASE-T and exclusive for 100BASE-T. In use of G-50A the hub should be selected one which 10BASE-T is available. What is cascade connection? This is to connect between multiple ports of hub with cable in layered structure. The port can be added on. Restriction on the number of layer in cascade connection: The increase in the layer of cascade leads delayed time to become longer, resulting in bringing the impossibility of collision detection. Therefore, the limitation on the number of layer of cascade is provided as follows: * 4 layers for 10BASE-T * 2 layers for 100BASE-TX - 36 - (2) LAN wiring length 1) The wiring length of 10BASE-T connecting to G-50A is limited to 100m or less. 2) When the wiring length of LAN connecting to G-50A exceeds 100m, the following measures must be applied. a) Connect 10BASE-T up to 4 stages via HUB. This covers 500m maximum.

Method for Initial Registration on G-50A’s Own and on PC Monitoring with Initial Setting Tool (1) What is initial setting tool? This is a tool with which initial group setting of air-conditioner, registration of abnormal mail transmission, and registration of IP address such as that of dial-up rooter are carried out. 1) The conventional centralized controllers were required to input locally some sorts of initial settings such as those of group registration and group name. However, if data for initial setting are ready in advance with the tool, only local transfer of the data to G-50A makes initial registration possible, resulting in shortening local working hours. 2) But without using the initial setting tool, the following are not registered with G-50A main body: Be sure to register each of the following with the initial setting tool accordingly. "Setting of abnormal mail transmission", "Registration of gateway address", Registration of block setting". "Block" is a greater of group which is an operation unit. Therefore, registration work by means of the initial setting tool is required in the following cases: a) In case of monitoring on the Web, display and control in block unit are necessary. b) In case of remote monitoring by connecting to public circuit is performed. c) In case of abnormal mail transmission is made. d) In case of connecting by way of gateway using the existing LAN G-50A main body • • • • • • • Initial setting window Group setting Time setting Setting of ventilation interlocking Function setting Setting of M-NET address (Initial: 000) IP address setting (Initial: 192.168.1.1) Sub net setting (Initial: 255.255.255.0) Setting of initial setting tool • Setting of abnormal mail transmission • Block setting • Setting of gateway address • Setting of the name of G-50A/ID setting • User setting G-50A integrated software: The number of floor Up to 55 floors Group name Up to 20 characters Block name Up to 20 characters (2) Composition of initial setting tool 1) Software for G-50A initial setting (CD-ROM) 2) PC: Pentium 133MHz or more, Windows98/Me/2000, 64MB or more, HDD 20MB or more, self-contained LAN port or one LAN card, and CD-ROM driver 3) LAN connection cable for initial setting PAC-YG00FA (option) or local LAN cable Three patterns of connection between G-50A and PC are available. a) Data transfer with LAN connection cable for initial setting connected to the connector for G-50A front face maintenance * Connection with cable for LAN exclusive use may be impossible due to the compatibility of LAN card.
