2. DESCRIPTION 2.1. Introduction Transponders provide positioning and message information to trains. The onboard cab system uses data obtained from transponders to enforce permanent and temporary speed limits. Transponders are installed between the rails (see Figure 2-1) and can be mounted on the ties or between the ties. Refer to your railroad’s installation drawings for specific mounting information.

Figure 2-1. Transponder Installation

2.2. Purpose The primary purpose of the transponder is to transmit the resident telegram message from its internal memory to the passing vehicle. The user bit data of each transponder of a base package and one or more optional packages of data. An example of some base information would be:

• Transponder position along the track • Linking distance to the next transponder set • Configuration of the group (total number of transponders in the group)

2.3. Physical Description The transponder (STS USA part number L340000000) (Figure 2-2) is a rigid, compact, and sealed device that is mounted between the rails. It is approximately 1.6 x 9.9 x 16.8 inches in size. The electronics are mounted in a sealed compartment in a molded plastic structure. This ensures protection for the electronics in an outdoor environment. The transponder cannot be opened to repair the internal circuitry. The transponders are programmed with 180 bits of information and activated by the carborne system. A PC with the TranEdit program installed is used to program the transponder. A transponder tester is used to load the telegram message onto the transponder and to read the telegram message from the transponder. See Section 5for transponder tester information.

2.4. Transponder Layouts A transponder layout contains a minimum of two transponders but can have as many as four transponders. The number of transponders at a location is dependent upon the amount of information that has to be stored and transmitted to the vehicle. The distance of the first transponder is 14 feet from the insulated joint. The remaining transponders are placed 11 feet apart. Refer to the railroad's Book of Plans for specific installation arrangements. Various transponder arrangements are based on the type of signal, territory type, and data space requirements. A typical transponder arrangement is shown in Figure 2-3.

Figure 2-3. Example of a Passive Transponder Arrangement

2.5. Mounting The following paragraphs describe a typical mounting of the transponder. Refer to your railroad’s book of plans for specific mounting information.

The transponder is designed to be mounted flat on a tie by two bolts, two flat washers, and a mounting mat (STS USA part number L34000 9510) (See Figure 2-4 ). M10 or M12 bolts may be used. M10 bolts have strength enough to keep the transponder in place, but M12 bolts are recommended in order to get a greater pressure surface at the fastening point. If M10 bolts are used, use a tube to fill the gap between the bolt and the transponder’s mounting hole. The tube is installed in order to ensure that the transponder will stay in its position. The mounting bolts should be tightened until the rubber mat just begins to compress. The mounting bolts must penetrate the tie by more than 2.76 inches (70mm). If the transponder bolts cannot be fastened into the tie, a mounting bracket can be used.

Figure 2-4. Transponder Mounting Example

The transponder can be oriented in two ways between the rails: transverse or longitudinal. Longitudinal gives a little longer contact area. The main method is to mount the transponder transversal. The transponder must be mounted in the center of the track with a tolerance of ± 0.4 inches (10mm).

3. FUNCTIONAL DESCRIPTION 3.1. System Operation The passive transponder is programmed with territorial information pertaining to signal targets, civil restrictions, and other local information. Passive transponders transmit only their self-contained telegrams and are not connected to any other devices. The message from the transponder is called a telegram and is a total of 255 bits in length.

NOTE

Some applications split the 255 bits as follows: 180 data bits, 3 filler bits, and 72 bit CRC

The telegrams are different for each transponder and are stored in the transponder's memory. As a vehicle passes over a transponder, the vehicle's antenna transmits a 27MHz signal. When the 27 MHz signal energizes the transponder circuitry, the transponder transmits the stored telegram to the vehicle. After the vehicle passes over the transponder, the 27 MHz signal is no longer present to provide an energy source for the tag. The type of information contained in the message varies from railroad to railroad. 3.1.1. Direction of Travel Transponders can contain information for both directions. The up direction of travel means that the train reads the first transponder in the set beginning with the #1 transponder, then the #2 transponder, and so on to #3 and #4 if present. The down direction means that the train reads the transponders in a declining sequence. If a transponder set consists of only two transponders, the train could read transponder #2 and then transponder #1 or transponder #1 and then #2. This is dependent upon direction. 3.1.2. Transponder Identification Each transponder set has a unique identifier encoded within the telegram data string that indicates its positioning point inside the network. The use of this unique identifier that includes the line number, milepost location and track number does not permit any two transponder sets to have the same identifier. 3.2. Telegrams The telegrams are preprogrammed and stored in the transponder's memory. The contents of the telegram is application and location specific. The generation of transponder messages is the responsibility of the system designers. Users are responsible to load and verify that the telegrams are correct per the system design in the event that a transponder fails and is replaced.





4. MAINTENANCE AND TESTING 4.1. Introduction The transponder does not require scheduled maintenance. When a fault is noted, the entire unit is to be taken out of service and replaced with a known functioning unit. Failure of a transponder can be total or partial. 4.1.1. Partial Failures A partial failure is when one or more bits are sent with incorrect values, i.e., memory faults etc. The CRC check detects whether incorrect data has been sent. If the CRC for the received message is incorrect, the complete message is discarded. The detection of a partial failure is then the same as a total failure, both result in the loss of all information from the transponder. 4.1.2. Total Failures Total failure is when no part of a message is received from a transponder. 4.2. Inspection The following inspection checks are to be performed after any repair, removal, and/or replacement activities due to device failures:

1. Check that the protective cap is mounted properly on the cable connector. 2. Look for mechanical damage such as cracks and if it was jarred from its originally

installed position. 3. A check for loose or missing fastening bolts. 4. Verify there are no undesired metal objects close to the transponder other than

its mounting plate. 5. Verify the transponder is properly installed and securely fastened to the mounting

plate and tie. 4.3. Testing The only test necessary for the transponder is to test the preprogrammed telegram message contained in its memory and to compare it against the design. 4.3.1. Test Equipment The following test equipment is used to test the transponder:

• Transponder tester (L34100000). See Section 5 for transponder tester information. • PC with associated software (TranEdit and Windows 95 or later) • Appropriate CRC files



NOTE

The file extension used is .CRC. The file contains all 255 bits of the telegram.

4.4. Test Procedure Proceed as follows to test the transponder:

1. Open the TranEdit program on the PC. 2. Select File and then select Open. See Figure 4-1.

Figure 4-1. TranEdit File Open Screen

3. Select and Open the appropriate CRC file. See Figure 4-2.

Figure 4-2. Open CRC File Screen

4. The telegram contents of the selected file will display. See Figure 4-3.



Figure 4-3. CRC Screen

5. Place the transponder tester on top of the transponder and turn the power switch to the ON position.

6. Press the READ TRANSPONDER button momentarily. The telegram will be displayed on the LCD of the tester.

7. Compare each digit of this telegram with the displayed CRC file on the PC. If the characters are the same, the correct telegram message has been programmed into the transponder. If the characters do not match, reprogram the transponder as described in Section 6.3.





5. TRANSPONDER TESTER The tester is a stand-alone device (see Figure 5-1) that is used to read the transponder telegram and to program the transponder. There are no setup requirements for the tester. The tester can be used as a standalone unit for checking the telegram message. For programming, the transponder must be connected to a PC running TranEdit software. The controls and connectors of the tester are as follows:

• Power ON/OFF switch • Battery charger connector jack • PC cable connector • Transponder cable connector • LCD and pushbutton control area

Figure 5-1. Transponder Tester

5.1.1. Tester Battery The tester uses a rechargeable 1.2 Ah 12V sealed lead-acid battery. To conserve battery capacity, turn the tester to OFF when not in use and disconnect the programming cable immediately after transponder programming. In normal use the



tester should maintain its charge for a full day of intermittent operation. When used constantly, keep the charger connected to the tester when in the workshop. 5.1.2. Tester Operation Figure 5-2 shows the front panel controls used to operate the tester. There are four basic functions used for all required operations.

Figure 5-2. Tester Control Panel

5.1.3. Read Transponder The READ transponder button checks that the transponder sends the required signal level back and that the telegram is correct. The telegram is shown in hexadecimal form for the 255 bit telegram if the transponder is working. If the transponder is not responding, NO BALISE will be shown on the display and the unit will provide higher and higher transmitter levels to search for the transponder. 5.1.4. Check Transponder The CHECK button activates the tester's transmission-test function to test the condition of the transponder. The tester increases the transmission effect to a specified level. If the received telegram is correct, the tester displays GOOD RESPONSE AT HIGH LEVEL. The tester then proceeds to a lower level. If correct, the display displays GOOD RESPONSE AT LOW LEVEL. If the test fails, the display will show BAD RESPONSE……. If the test function stops without giving any of the above messages, press the CHECK button again. A counter is displayed in the upper right corner to indicate that an ongoing test sequence is taking place.

5.1.5. Read Encoder NOTE

This function is not used with a passive transponder.

Connect the tester to the encoder cable (L34100 4006). By pressing the Read button the tester will check information on the encoder cable at a definite minimum level and show the detected telegram on the display. 5.1.6. Simul Encoder

NOTE

This function is not used with a passive transponder.

Place the tester on top of the transponder and connect the programming cable (L34100 4016). Activate the encoder simulation function by pressing the Simul button. The tester sends an encoder telegram to the transponder and checks if the transponder retransmits the telegram correctly. This function provides the ability to verify a transponder can receive and transmit a telegram from an encoder when the operator is troubleshooting for system failures. In Simul Encoder mode the transponder tester is sending a simple 1 0 1 pattern to the transponder. The response from the transponder is checked in the tester. If the telegram is correct then it will be recognized as such by the tester. The transponder tester has two LED indications above the encoder pushbuttons. Pressing the Simul encoder pushbutton will initiate the following sequence: When the tester’s transmitter is ON the “TX” LED is lit. When data is received from a transponder the ‘RX’ LED is lit and the display will indicate ‘Encoder Data Received’. 5.1.7. Serial Data Cable A Null-modem type cable is used. Pins 2 and 3 crossed in cable, pin 5 (pin 7 on 25-pin) are common (STS L341004014).

• Tester end: 9-pin D SUB male • PC end: 9 or 25-pin D SUB female.

5.1.8. Programming and Testing Cables Cable for connecting the Transponder Tester to the transponder. Part no. L34100 4008. 5.1.9. Self-test Each time the transponder tester is turned on, a self-test sequence starts. If a failure is not detected, the sequence ends with a battery status message and the message "Ready" appears on the display.



If a failure is detected, the self-test sequence is stopped at the detected position. Possible tester failures are displayed with the following messages:

Error: in prog. voltage Error: in prog. pulse length Rom error Error: low output level Error: low receive level Error: in reading data

In case of failure, the unit has to be sent to STS USA for repair. 5.1.10. Battery Status and Replacement When the test is completed the display reports status of the battery: xx% CHARGED -READY. If the battery monitor detects too low of a capacity ("0%"), the display starts flickering and a RECHARGE BATTERY message is displayed. The unit is equipped with a long-life battery that dramatically reduces the need for replacement. Should the need arise to remove and replace the battery, proceed as follows:

1. Open the tester by unscrewing the four Philips screws in the corners of the panel. 2. Lift out the panel and place it upside down on a clean work surface. 3. The battery is placed between the two tinned screen-boxes and fixed by a

bracket. 4. Unscrew the two screws and the battery can be exchanged.

5.1.11. Tester Fuse To protect the electronics and battery, a fuse is inserted in the battery cable. In the case of wrong polarity or short-circuit, the fuse will protect the cables from burning due to the high current capacity of the battery. If the unit does not start or the battery does not take a charge, suspect the fuse.



Open the tester as described for battery replacement. The fuse is installed on the red cable connected to the battery.
