Purpose of Manual
Section 1. Purpose of Manual This manual provides an overview of two-way End-of-Train (EOT) Telemetry and detailed information regarding the installation and operation of the US&S DIGITAIR® Model 6680 Communication Interface Unit (CIU).
1.1. General Overview of Two-Way End of Train Telemetry A two-way End-of-Train (EOT) telemetry system consists of an EOT Cab Unit, which is mounted in the locomotive cab, and an EOT End Unit, which is mounted on the coupler of the last train car (Figure 1-1). These two EOT units communicate with each other via radio. The Cab Unit incorporates all of the functions necessary to communicate with the End Unit. When the locomotive is equipped with an Integral Locomotive Computer (ILC), a CIU such as the US&S DIGITAIR® Model 6680 CIU is typically used as the EOT Cab Unit. The CIU interfaces to the ILC, which displays all relevant EOT information for the locomotive operator. The CIU, together with an EOT End Unit and an ILC, operating as a system, provides the following information and capability: •
A digital display of the brake pipe pressure at the rear of the train;
•
An indication of motion of the last car (moving/stopped) and its initial direction (forward/reverse);
•
The status (weak or replace) of the End Unit battery;
•
A warning of low brake pipe pressure (typically less than 45 psig);
•
The status (On/Off) of the Highly Visible Marker (HVM) light if supplied on the End Unit;
•
The status of the radio link (rear-to-front and front-to-rear communications);
•
An emergency braking function from the rear of the train, when operating in two-way mode;
•
A digital display of secondary air pressure if a dual pressure type End Unit is used. LOCOMOTIVE LAST CAR RADIO LINK END UNIT HVM

Purpose of Manual
1.2. CIU General Overview and Functional Description The DIGITAIR® Model 6680 CIU receives and processes EOT telemetry radio messages from an EOT End Unit and sends the data extracted from these messages to an Integral Locomotive Computer (ILC) via an asynchronous serial connection for subsequent display. When the EOT system is operating in two-way mode, the CIU receives Emergency Brake and Communications Test commands from the ILC and transmits these commands via radio to the EOT End Unit. The CIU is a single unit (Figure 1-2) which mounts in an Integrated Cab Electronics (ICE) type rack. It communicates with the ILC via a cable connected to the Host Interface connector on the front panel of the CIU. The Host Interface connector provides the lines required for an external DC power source and CIU-to-ILC serial communications. The CIU is connected to a UHF 1/4-wave antenna via the front panel mounted “N” type RF antenna connector.

Purpose of Manual
1.3. Radio Message Protocol Compatibility The CIU is compatible with the American Railway Engineering and Maintenance of Way Association (AREMA) End-of-Train message protocol as defined in Section.22.3.1 of the AREMA Communications and Signals Manual dated 2000. The CIU meets or exceeds the current requirements of the U.S. Federal Communications Commission (FCC) and Industry Canada (IC) regulations.
1.4. Compliance with Locomotive System Integration (LSI) and Integrated Functional Computer (IFC) Communications Specifications The CIU interfaces to either an Integral Locomotive Computer (ILC) or an Integrated Functional Computer (IFC) via an asynchronous RS-232C serial communications link. The CIU has been designed to comply with the current Locomotive System Integration (LSI) Communications Specification prepared for the AAR. The CIU’s communications electrical characteristics, data format, and message block protocol operate as defined in the LSI Communications Specification, Appendix A and Appendix G. Per Appendix G, the LSI specifications have been established to facilitate forward and backward compatibility with units fielded on GE LSI and EMD FIRE and ICE locomotives. EMD's Integrated Cab Electronics (ICE) requirements are a subset of the LSI specification.
1.5. CIU Ordering Information To order the DIGITAIR® Model 6680 Communication Interface Unit (CIU) and related accessories, please contact US&S Customer Service at 1-800-652-7276 or your local US&S Sales Representative for technical information, pricing, and additional sales information. 1.5.1.
CIU Part Number
The CIU bears US&S part number N24300102. It will operate with either an IFC or LSI/ICE/FIRE system when appropriately configured. 1.5.2.
CIU Diagnostic and Configuration Software Disk
The CIU does not rely on a dedicated external device for system diagnostics or configuration. All of the unit diagnostic tests and configuration functions are included on a Diagnostics and Configuration Software Disk that runs on a standard DOS-compatible personal computer (PC). The PC is connected to the CIU’s internal DB-9 style Diagnostic Port or it can be optionally accessed via the Host Interface connector. The Diagnostic and Configuration Software permits easy customization of the CIU’s operation. Most of the variable default values and functions are user selectable. These variables are set by the factory at the time of purchase or by railway technicians via a PC at installation. The Diagnostic and Configuration Software program on the disk is named “diagunit.exe” and its use is described in Section Section 3. SM 7072, Rev. 1, March 2004
1-3
Purpose of Manual The Diagnostic and Configuration Software Disk (3.5”) can be ordered under US&S part number N451232-1264. 1.5.3.
CIU Executable Software and Load Utility Disk
The CIU uses FLASH type, programmable, non-volatile memory to store its application software. This type of memory eliminates the need to disassemble the unit and physically replace an EPROM in the event that software upgrades are required. The Executable Software and Load Utility disk allows the user to download software upgrades into the CIU’s internal FLASH memory. It contains two files: (1) the latest upgrade version of the CIU executable software named “ciu.hex”, and (2) the Cab Unit Flash Loader program named “load.exe”. The use of this disk is described in Section 4.2. This disk is will only be issued by US&S when an upgrade is deemed necessary. The latest version of the CIU Executable Software and Load Utility disk is available on a 3.5” diskette under US&S part number N451232-0822.

Installation of the CIU
Section 2. Installation of the CIU This section describes the installation of the CIU. Installation includes mounting the unit and connecting the unit to a DC power source, the Integral Locomotive Computer (ILC), and a UHF antenna. Configuration and verification of proper operation after power-up are also described. 2.1.
Items Required for Installation and Configuration
Items required to install the CIU include the following: •
CIU (P/N: N24300102)
•
Diagnostic Software Disk (P/N: N451232-1264)(Section 1.5.2)
Items to be supplied by the user include: •

•
ILC Host Interface Cable
•
1/4-wave UHF Antenna terminated with an N-type RF connector
•
PC serial communications cable, 9-pin “D” type, straight-through, male-to-female connectors.
2.2. Mounting the CIU The CIU is housed in a Communications Interface Unit (CIU) style enclosure, designed to be mounted in an Integrated Cab Equipment (ICE) rack. However, the CIU may also be mounted in any available location in locomotives equipped with other types of on-board integrated cab equipment. 2.2.1.
Mounting the CIU in an Integrated Cab Electronics (ICE) or LSI Rack
To mount the CIU in an ICE or LSI rack, align the two rear mounting holes with the two mating pegs at back of the rack. Secure the CIU in place by tightening the rack’s fastener nut over the front panel bracket. 2.2.2.
Mounting the CIU in a Non-ICE Equipped Locomotive
If the CIU is to be installed in a non-ICE equipped locomotive, it can be mounted in any suitable location such as an empty equipment shelf as deemed appropriate. However, because the CIU is meant to be rack mounted, it does not incorporate mounting tabs and appropriate mounting hardware for the location must be used to secure the CIU.

2.4. Host Interface Cable and Connections US&S does not supply the Host Interface cable because of the many variations that can exist in the type of integrated cab computer used in the locomotive and the location where the CIU may be mounted within the locomotive. The Host Interface cable shall be provided by the user. Figure 2-1, Host Interface connection diagram, can be used as a basis for typical connections to the CIU. It should be noted that Protocol selection is usually handled by the installation of a single jumper wire within the shell of the Host Interface Connector on the locomotive wiring harness. The installation of the jumper wire between pins P and C configures the CIU for LSI, FIRE, and ICE operation. The absence of the jumper wire configures the CIU for IFC operation. In a situation where the desired mode of operation is LSI, FIRE, or ICE and no protocol select jumper wire exists in the locomotive's wiring harness, the CIU can be configured using the diagnostics utility to always operate in the LSI/FIRE/ICE mode regardless of the wiring configuration. When this is done the CIU should be 2-2
SM 7072, Rev. 1, March 2004
Installation of the CIU labeled "CONFIGURED FOR LSI ONLY OPERATION" to prevent the unit from being installed in an IFC system without first reconfiguring the CIU.
2.5. Antenna Installation The antenna is generally mounted on the locomotive roof. If interference from nearby transmitting antennas (e.g., voice radio) is likely to be a problem, locate the antenna as far away from competing signal sources as possible. The recommended antenna is a 1/4-wave UHF-type unit with the required cable length terminated in an N-style RF connector. A low-loss coax cable is recommended. Connection to the CIU is accomplished by attaching the “N”-type connector onto the CIU’s front panel mounted Antenna connector. HOTDCIU HOST INTERFACE CONNECTOR

Installation of the CIU
2.6. CIU Power Up and Operational Verification The CIU has no power switch and normally receives its power from the locomotive radio circuit breaker or ILC power source. After the CIU has been properly installed, perform the following steps to ensure proper operation: 1. Power-ON the unit via the locomotive radio circuit breaker or ILC power source. 2. Confirm that the green STATUS indicator on the front panel is flashing. This indicates that the CIU software is running and that the processor board is operational. 3. The CIU is now ready for operational verification. 2.6.1.
CIU System Operational Verification
The following basic system functional checks should be performed after a new CIU is installed. The functional checks are designed to verify that the CIU is transmitting and receiving EOT radio messages to/from an operational End Unit, and is communicating with the ILC: 1. Obtain a known operational End Unit. (It may be operated outside the locomotive. No pressurized air is necessary.) 2. With the CIU powered, use the ILC console to enter the ID code of the End Unit. 3. Press the TEST button on the End Unit to activate it. 4. Initiate a Test Request command from the ILC console. Verify that the CIU responds by observing that the ILC displays “Self test passed.” If the End Unit is not connected to a pressurized air source, the Pressure field should indicate 0 psig. This should be accompanied by a Low Pressure indication on the ILC since the pressure is below the standard 45 psig threshold. 5. Initiate a Communication Test Request/Arm command from the ILC. Verify that the ILC indicates “Confirmation received.” This confirms proper operation of the CIU’s RF transceiver and associated control circuits. This completes the basic system functional checks.

SM 7072, Rev. 1, March 2004
Configuration and Diagnostics
Section 3. Configuration and Diagnostics The CIU incorporates a Diagnostics Port to access built-in configuration and diagnostic functions. This port, which is comprised of a 9-pin “D” type RS-232-C serial connector, is located on the processor board (J6) inside the CIU’s enclosure. However it can also be accessed without removing the CIU cover via its Host Interface connector. The port connects to a DOS compatible PC via a standard straight-through, male-to-female 9-pin “D” type serial computer cable which is available at most computer and office supply outlets.
3.1. DIGITAIR® Diagnostic Software DIGITAIR® Diagnostic Software running on a PC provides a full set of user friendly, menu driven configuration and diagnostic functions. The Diagnostic Software is a single program named “diagunit.exe” supplied on a floppy disk. The software can be ordered under US&S part number N451232-1264 (3.5” disk). NOTE This manual provides detailed information on CIU configuration with limited examples of the diagnostic functions. For detailed diagnostic information and procedures, refer to US&S Service Manual SM 7073 (Shop Maintenance).
3.2. Running the Diagnostic Software To run the Diagnostic Software, perform the following: 1. Turn OFF power to the CIU. 2. Plug the PC serial cable into the CIU’s Diagnostics Port by either removing its cover, or via the Host Interface connector located on the CIU. (See Figure 1-2 for the location of the Host Interface Connector and Table 2-1 for pin assignments. See Figure 1-3 for location of the Diagnostic Connector.) CAUTION The CIU contains static-sensitive components. Always observe proper ESD handling procedures or equipment damage may result. 3. With the diagnostic PC powered-on, execute the Diagnostic Software from the floppy disk (or from the PC’s hard disk if it has been copied there) by typing “diagunit” followed by

CIU Software Upgrades
Section 4. CIU Software Upgrades The CIU uses FLASH type, programmable, non-volatile memory to store its application software, as opposed to an EPROM chip. This eliminates the need to disassemble the unit and physically replace the EPROM for software upgrades. Software upgrades are supplied by US&S on a CIU Executable Software Disk containing two files: (1) the latest upgrade version of the CIU executable software named “ciu.hex,” and (2) the Flash Loader program named “load.exe.” This is a 3.5” disk and is available under US&S part number N451232-0822. Software upgrades are downloaded into the CIU’s Flash memory from a PC connected to the unit’s internal Diagnostics connector via the same 9-pin “D” type serial cable used for performing diagnostics. Downloads can also be performed without the need to remove the cover via the CIU’s Host Interface connector as shown in the connection diagram (Figure 2-1). The download function is performed by running the Flash Loader Software as detailed in the following sections.
4.1. Flash Loader Utility Program The Flash Loader program is named “load.exe” and runs on a DOS compatible PC. Although this program may be run from the floppy disk drive, it is preferable to copy it to a directory on the PC’s hard drive. The new Upgrade Version of “ciu.hex” must reside on the same floppy disk or hard drive directory containing “load.exe.”
4.2. Using “load.exe” At the PC DOS prompt, the command syntax for “load.exe” can be viewed by typing in load followed by pressing . The PC will display the command structure as follows: Cab Unit Flash Loader (Rev 1) Thu Jul 18 16:11:41 EDT 1996 Usage: load - [-r] where - is -COM1 or -COM2 is the executable to be loaded in Motorola Exormax format. -r means run the program after loading (optional) Use a straight-through cable from the PC to the Unit. Therefore, the typical command line, depending on the PC serial port being used, will be: load -COM1 ciu.hex -r or
if PC serial port 1 is being used;
load -COM2 ciu.hex -r if PC serial port 2 is being used. SM 7072, Rev. 1, March 2004

4.3. Procedure for Downloading CIU Software Upgrades To download CIU software upgrades, perform the following: 1. On the PC, copy the new Upgrade Version of the file “ciu.hex” to the floppy disk or hard drive directory containing the Flash Loader Software “load.exe.” 2. Turn OFF power to the CIU. 3. Remove the CIU’s cover and connect one end of the serial cable to the CIU’s internal Diagnostics connector and the other end to one of the PC’s serial ports (either COM1 or COM2). Note that this is connected in the same fashion as described in Section Section 3 - Configuration and Diagnostics. Alternately, the PC can be connected to the CIU’s Host Interface connector. This eliminates the need to remove the CIU’s cover. 4. Apply power to the CIU. 5. On the PC, enter the load command for the Flash Loader as follows: load -COM1 ciu.hex -r
if PC serial port 1 is being used;
or load -COM2 ciu.hex -r
if PC serial port 2 is being used.
The PC will display the progress of the download process as follows: Cab Unit Flash Loader (Rev 1) Thu Jul 18 16:11:41 EDT 1996 Press a key at any time to quit this program. Initiating target diagnostics: Cab Unit Boot Prom (REV 1) Thu Jul 18 9:37:47 EDT 1996 ROM test PASSED RAM test PASSED Erasing flash ... done. Writing to flash ... #### records downloaded. 6. Upon completion of the download, the CIU will begin running the new upgrade software in the normal fashion just as it does on standard power-up. The green STATUS indicator mounted on the CIU’s front panel should be flashing, indicating that the new upgrade program is operating correctly. 7. Remove power, unplug the serial cable from the CIU, and reinstall its cover (if applicable). The CIU is now ready for operation.
