TD220_manual12.doc Page 4 of 38 1/10/2011 2 Introduction The GE MDS TD 220 is a 25-Watt 220 MHz GMSK data radio intended for bridging ITCS messages over the air between locomotives and wayside devices. The data interface is Ethernet, with UDP-
encapsulated ITCS message payload. Second 0 Each second is divided into 8 133-byte time slots. The first of the 8 timeslots each second is always reserved for bases A, B, or C to transmit beacon information to the mobiles in the area. Following the beacon are 4 (or 5) time slots that are always reserved for mobiles to transmit. At the end of each second, are 3 (or 2) time slots that can be used by bases or mobiles. These slots are used with the following priority: the previous base, the current base, and then mobiles. In other words, during second 1 in the table below, base A actually has priority over the last three slots. If A does not use them, B can use them. If B does not use them, mobiles can. Bases reserve these time slots with flags in the beacon. This scheme maximizes the potential for utilizing all slots. 0 A 1 M 2 M 3 M 4 M 5 C or A or M 6 C or A or M 7 C or A or M While this radio has been designed to pass ITCS messages, it can pass generic UDP traffic following the conventions outlined in the following figures.

TD220_manual12.doc Page 8 of 38 1/10/2011 4 Common Setup Tasks 4.1 Key the Transmitter for Test Purposes 1. Log in to the radio on its COM1 console using a serial terminal emulator program. 2. Go to the Radio Configuration menu. 3. Select the frequency for the test transmission. 4. Select the RF Output Power to use. Note that power levels greater than 2 Watts will timeout after a 5-second period by default. Ensure ventilation with supplemental forced airflow if longer durations are desired. 5. Select the Force TX Key menu option. 6. When finished, deselect the Force TX Key menu option. 4.2 Prepare the Network Interface for a Radio Each radio is assigned an IP Address, a Netmask, and a Gateway IP Address. The IP Address and Netmask should be chosen carefully. The radio will network directly with other equipment with IP Addresses that are on a common Subnet. IP Addresses that begin with the same numerical IP address bits where the Netmask is one will be on the same Subnet. For example, if the IP Address is 10.4.100.1 and the Netmask is 255.255.0.0, the radio will attempt direct Ethernet communication with any node whose IP Address begins with 10.4. If a message is bound for a node outside of the 10.4 network, it will be sent to the Gateway IP address instead so that it can be placed from the radios subnet onto another subnet. 1. Log in to the radio on its COM1 console using a serial terminal emulator program. 2. Go to the IP Configuration menu. 3. Set the IP address of the radio, plus the Netmask and Gateway. 4. Go to the Maintenance/Tools Menu and select the Ping Utility. 5. Enter the IP address of a known node on the network. 6. Execute the Ping and observe the results. If the network interface is working properly, Ping responses should be received. 4.3 Set Up a Base Unit If not already done, complete steps from 4.2 above. 1. 2. Connect the RS-232 NMEA serial data output from the GPS receiver to the Base Radio via the radios COM2 port. Drive serial data into the radio on DB-25 pin 2. 3. Connect the GPSs PPS output to the Base Radio. Drive TTL into the radio on DB-25 pin 23. 4. Log in to the radio. 5. Go to the System Configuration menu. 6. Set the unit to Base mode and reboot if necessary. 7. Set the base type (A, B, or C). 8. Set the window size. Mobiles will transmit in a randomly selected available slot among 2^(Window Size) slots. For small networks, this can be 1. For larger networks, use a Window Size that provides double or quadruple the number of mobiles expected under one base at a time. 9. Set the IP Port on which the base will receive UDP messages from wayside devices. 10. Set up an ITCS Translation Table. For test purposes, this may be as simple as setting up one known address with a mask of all Fs. 11. Verify Ethernet Link using the Ping utility in the Maintenance/Tools Menu. 12. Begin sending UDP data. 13. Verify the TX LED illuminates and the radio begins transmitting over the air. TD220_manual12.doc Page 9 of 38 1/10/2011 4.4 Set Up a Mobile Unit If not already done, complete steps from 4.2 above. 1. 2. Log in to the radio. 3. Go to the System Configuration menu. 4. Set the unit to Mobile mode and reboot if necessary. 5. Set the IP Port to which the mobile will send messages received over the air. 6. Set the IP Port on which the mobile will accept incoming messages for transmission over the air. 7. Verify Ethernet Link using the Ping utility in the Maintenance/Tools Menu. 8. Ensure at least one base is present in the neighborhood of this radio so that it can detect beacons and synchronize timing. 9. Begin sending UDP data from a polling program. 10. Verify the TX LED illuminates and the radio begins transmitting over the air. 4.5 Perform Test Polling 1. Set up the Base and Mobile as above. 2. Connect as shown in the following diagram. Note: this is for bench testing only, i.e. not for sensitivity testing. Sensitivity testing requires complete RF isolation or mixed operation to prevent the leakage path from being the dominant RF path between units. For bench testing, use attenuation so that the signal level at every unit that is participating is around 70 to 50 dBm.

Symptom Radio is alarmed (PWR LED is flashing) Alarm: GPS PPS Not Available Alarm: GPS Signal Inverted Alarm: NMEA Data Invalid Radio shows messages are received via Ethernet, but it will not transmit over the air. Possible Cause Check the alarm list accessible from the Starting Information Screen. Radio is not receiving a PPS. Although a PPS has been detected, it is in the ACTIVE state for more than a half of a second. Try switching the PPS Polarity setting on the GPS Configuration Menu. The radio is not receiving valid NMEA GGA Sentences. Verify that the NMEA Baud rate is set correctly and verify that the GPS is outputting ASCII GGA sentences (and no others, if possible). Radio is alarmed. TD220_manual12.doc Page 34 of 38 1/10/2011 7 ITCSLOG Utility The ITCSLOG utility is a PC program that receives, displays and captures logging messages sent from TD220 radios. ITCSLOG messages are diagnostic messages used to track and analyze the message flow between radios. The radios generate two log messages for each payload message it processes. The first message is the Header Message and it contains the information about the processing of the payload message. This information is displayed on the ITCSLOG Window (below). The second log message contains a copy of the Payload data. TD220_manual12.doc Page 35 of 38 1/10/2011 Parameter IP Port Number Action Description R/W The port this program will use to receive ITCSLOG messages. This program can collect log messages from multiple radios as long as they have an Ethernet connection and are configured with the correct IP Address and Port Number. Start Monitoring Button Causes the program to start processing log messages. 1. Create the log file, 2. Open the UDP Port 3. Read and process log messages Show Console Hide Console Button Causes the program to display the capture console window. Button Causes the program to hide the capture console window. The IP Address and Port Time RSSI Direction Zone Slot Log File R R R R R R R program is still processing messages while the console is hidden. The IP Address and output port of the radio sending this log message. The Date and Time when the PC received the message. This is based on the PCs time. The RSSI value of the message when received by the radio. This field is only populated for messages received OTA by the reporting radio. Indicates whether the message is Base to Mobile (B->M) or Mobile to Base (M->B). Indicates the type of radio transmitting the message OTA. It may be BASE_A, BASE_B, BASE_C or MOBILE. Note that a Base may transmit a message in a second other than its own. This is the Timeslot the message was transmitted/received in. The value 1-24 represents the 3 seconds within the EPOCH and the 8 timeslots within a second. Note that for log messages prior to release 1.4.0 did not include the slot value. This field is set to N/A for these messages. Note also that the Timeslot value of zero is used to indicate messages that were not transmitted due to their age. The field is set to Dropped for these messages. This is the name of the file used to capture the message log. The file name includes the date and time that the capture was started. Stop Monitoring Button Causes the program to stop processing log message. 1. Stop reading log messages 2. Close the log file 3. Close the UDP Port EXIT Button Causes the program to stop processing log messages (if it is) and terminate. Below are lines taken from a log file created by the ITCSLOG utility. These lines reflect the processing of a single payload message. First, there is a Header Message from a Mobile, which is about to transmit a message in Timeslot 21. Next, the Data Message shows the content of the payload message, which will be transmitted. The next Header Message is from the Base radio that received the payload message OTA. This Header Message reflects that the message was received from a Mobile in Timeslot 21. 2010-06-11 14:11:47: Received 12 bytes from 10.4.199.10 1026:
