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. 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.

A time division channel access method is used by the TD220X for wireless communication. Each second is divided into 8 133-byte time slots. The radio further defines a multi-second epoch to allow the effective number of time slots to be scaled according to system design. Radios must be configured with the same epoch size.

Precise synchronization of timing amongst radios is necessary for operation. Each radio can be configured to use one of three timing sources: GPS, Precision Time Protocol (PTP), and over-the-air (OTA). While system design can be flexible, a base radio installation typically uses either GPS or PTP timing and a mobile radio typically uses OTA to synchronize to the wireless transmissions of a base radio. Radios configured for GPS timing must be connected to an external GPS unit to receive NMEA sentence information and the PPS signal. Radios configured for PTP timing will interact with a PTP Grandmaster Clock over the Ethernet port using IEEE 1588 (PTPv2). Radios configured for OTA timing use messages received wirelessly in the first time slot of each second to maintain timing.

With its time slot definition and variable epoch size, the TD220X provides a generic TDMA implementation that can be used by an external Communication Manager (CM) to support a variety of TDMA schemes. A CM is responsible for making decisions regarding timeslot, frequency, power, and payload organization. The TD220X is responsible for requesting data from a CM for upcoming timeslots, forwarding messages received wirelessly to a CM, and wirelessly transmitting messages received from a CM using the specified timeslot, frequency, and power. All communication between the TD220X and a CM is done using STFP.

4 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. 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 radio’s 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 Upgrade the Firmware

4.3.1 Introduction

From time-to-time MDS will offer upgrades to the TD220X firmware. Uploading new firmware into the radio does not require that the radio be taken off-line until you want to operate the radio from the new firmware image. You must use the TD220X’s embedded Menu System for all firmware activities, including uploading firmware from a TFTP server. The Menu System can be accessed in one of two ways:

 Terminal-Emulator—Use a terminal emulator program on your PC, such as HyperTerminal

or Putty, connected directly to the TD220X COM1 port via a serial cable.

 Telnet—Text-based access to the Menu System through a network connection.

Firmware images are provided free-of-charge on the MDS Web site at:

http://supportcentral.ge.com/products/sup_products.asp?prod_id=181796

4.3.2 Installing TD220X Firmware by TFTP

To use this function the user will need:

TD220X_manual_v8.doc Page 9 of 48 1/27/2017

 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.) A TFTP server can be found on the MDS web site at:

http://supportcentral.ge.com/products/sup_products.asp?prod_id=181796

4.3.3 Upload Procedure

To upload a new firmware file (tdx-krmd-X_Y_Z.mpk) into the TD220X unit use the following procedure:

1. Launch a TFTP server on a PC connected either directly or via a LAN to the Ethernet port

(LAN) of the radio. On the Options tab, set the outgoing path to the directory containing the firmware image file.

2. Connect to the radio’s Menu System by whichever means is convenient: Telnet via the LAN

or Terminal emulator via the COM1 port.

3. Go to the Reprogramming Menu.

(Starting Menu->Main Menu>Maintenance Menu>Reprogramming Menu)

4. Fill in the information for the: o TFTP Host Address – IP Address of the server (host computer) running the TFTP

server.

o Retrieve File – Name of the file (tdx-krmd-X.Y.Z.mpk) to be pulled from the TFTP

server holding the firmware file.

5. Pull the firmware file through the TFTP server into the TD220X radio.

(Note: the uploaded firmware image file replaces the “Inactive Image” file and

be automatically verified.)

6. Reboot the TD220X radio.

7. Test the radio for normal operation.
