TD220MAX_manual_v11.doc 1 Important Information 1.1 Antenna Installation Warnings 1. 2. All antenna installation and servicing is to be performed by qualified technical personnel only. When servicing the antenna, or working at distances closer than those listed below, ensure the transmitter has been disabled. Depending upon the application and the gain of the antenna, the total composite power could exceed 90 watts EIRP. For fixed/mobile configuration, the distances in the table below must be followed.
TD220MAX_manual_v11.doc 1.5 FCC Part 80 Notice For FCC Part 80, the Effective Radiated Power (ERP) must be less than or equal to 4 Watts for mobile use and 20 Watts for fixed use. This can be accomplished by adjusting the output power of the radio and selecting an antenna with appropriate gain. Consult the following table for assistance in setting the output power and selecting an antenna to maintain compliance. The table provides examples, however other combinations can be used.
TD220MAX_manual_v11.doc 2 Introduction The GE MDS TD220X is a 25-Watt 220 MHz GMSK data radio intended for bridging messages over the air between locomotives and wayside devices in rail applications or between ship and shore in maritime applications. The data interface is Ethernet and uses the UDP/IP-based Simple Timeslot/Frequency/Power Protocol (STFP), defined elsewhere. STFP is capable of supporting various payload protocols.
TD220MAX_manual_v11.doc 3 Interfaces 3.1 Data Interface (DB-25) The Data Interface has several ports integrated into one connector: Ethernet, COM1 and COM2 Serial Ports, and GPS signaling. Note that COM3 is connected internally and therefore not available on pins labeled with “COM3.
TD220MAX_manual_v11.doc 3.2 USB The radio provides a USB Port conforming to version 1.1 of the USB standard. This port is provided for features such as logging STFP messages to text files on a memory stick. Consult GE MDS for information on this feature. The pinout for this connector is given in the table below. Pin 1 2 3 4 Signal Name PC_USB_+5V USBDUSBD+ GROUND Description +5 VDC USB Data Minus USB Data Plus Ground 3.3 Power The power connector is a screw-secured 2-pin connector.
TD220MAX_manual_v11.doc Common Setup Tasks Note: For accessing the COM1 console, use a serial terminal emulator program such as HyperTerminal or Putty. The default settings are: baud rate 19200, no parity, 8 data bits, and 1 stop bit. The pins for this port are listed in section 3.1. 4.1 Key the Transmitter for Test Purposes 1. 2. 3. 4. 5. 6. Log in to the radio on its COM1 console using a serial terminal emulator program. Go to the Radio Configuration menu.
TD220MAX_manual_v11.doc 4.3.2 Installing TD220X Firmware by TFTP To use this function the user will need: A PC with a TFTP server running. The IP address of the PC running the TFTP server. If you do not know your computer’s address on a Windows PC, you can use the RUN function from the Start menu and enter winipcfg or ipcfg to determine your local PC’s IP address. The IP address of the radio can be found on the Starting Information Screen. (See Page 24.
TD220MAX_manual_v11.doc 14. 15. 16. 17. Go to the Maintenance/Tools menu. Verify the Ethernet Link using the Ping utility. Begin sending UDP data. Verify the TX LED illuminates and the radio begins transmitting over the air. 4.5 Set Up a PTP Base Unit 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. If not already done, complete steps from 4.2 above. Install and configure a PTP Grandmaster Clock. The clock must be connected to the base through the Ethernet Link.
TD220MAX_manual_v11.doc 11. Go to the Maintenance/Tools menu. 12. Verify the Ethernet Link using the Ping utility. 13. Ensure at least one base is present in the neighborhood of this radio so that it can detect beacons and synchronize timing. 14. Begin sending UDP data from a polling program. 15. Verify the TX LED illuminates and the radio begins transmitting over the air. 4.7 Perform Test Polling 1. 2. Set up the Base and Mobile as above. Connect as shown in the following diagram.
TD220MAX_manual_v11.doc 3. Configure the Base as follows: System Configuration Menu -==========================================================================A) Timing Source GPS B) STFP Radio ID 64 C) STFP Receive Port D) STFP Transmit Address E) STFP Transmit Port 53000 x.x.x.
TD220MAX_manual_v11.doc 5. Configure the Mobile as follows: System Configuration Menu -==========================================================================A) Timing Source OTA B) STFP Radio ID 0 C) STFP Receive Port D) STFP Transmit Address E) STFP Transmit Port 53000 x.x.x.

TD220MAX_manual_v11.doc 9. Set up the Poller as shown below, where 10.4.144.100 is replaced with the IP address of your base radio. Note: Set GPS Serial Port to None to prevent the utility opening a serial port. 10. Click Start Polling and observe the message counts and sequence number increment. The test will show 100% success if all messages sent to the base radio were transmitted over the air, received by the mobile radio, and forwarded back to the Poller.
TD220MAX_manual_v11.doc 11. The TX Message tab updates as messages are sent to the base radio. 12. The RX Message tab updates as messages are received from the mobile radio.
TD220MAX_manual_v11.doc 13. The Timeslot Map tab updates as messages are sent and received to show the distribution of messages across the available timeslots. Note: Only 48 timeslots are shown, supporting up to a 6 second epoch.
TD220MAX_manual_v11.doc 4.8 Perform Field Survey 4.8.1 Set up the Base System 1. 2. 3. 4. 5. 6. Set up a Base radio as above, using either a GPS or PTP timing configuration. Erect a representative antenna system and connect the antenna system to the radio with representative feedline. Ensure the radio is supplied with sufficient DC power to accommodate the intended transmit power setting.
TD220MAX_manual_v11.doc Notes: The Polling interval should be set to something fairly short to make sure the survey territory is adequately painted, however setting it below 500 ms or so may exceed the transmit duty cycle of the radio and/or overflow the radio’s input buffer and should be avoided. Setting “Stop After (polls)” to zero causes the base Poller to continue transmitting messages indefinitely. “Parse Response” can be set to “No” as the base Poller will transmit only.
TD220MAX_manual_v11.doc Note: Again, make sure you are authorized to transmit on the TX frequency you configure here. Make sure the transmit power is appropriate for the survey you are undertaking. 2 Watts shown above is the minimum power the radio puts out stand-alone. With an external PA, the radio is set to 2 Watts and the PA is adjusted to obtain the desired transmit power level. The power setting is in hex, so 25 Watts would be entered as 19 for example.
TD220MAX_manual_v11.doc 4.8.2 Set up the Mobile System 1. 2. 3. 4. 5. 6. Set up the Mobile Radio as above, such that it obtains its system timing “OTA” or over the air using beacons from the Base Radio. Obtain a GPS receiver that can output NMEA serial messages to a portable PC for logging purposes. Configure the GPS receiver to output only $GPRMC sentences. Run the Poller application on a portable PC or laptop to travel with the mobile radio.
TD220MAX_manual_v11.doc Notes: Set the mobile Poller’s “Stop After (polls)” value to zero to cause it to run until stopped manually. Set the mobile Poller’s “Parse Response” field to “Yes”.
TD220MAX_manual_v11.doc Notes: Make sure the RX Message tab looks like this. This tab is set up via the TD220X_Poller.parms file as shown above.
