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.
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.

The pin orientation as looking into the connector is shown below.
Consult the following table to determine how much current is required for receiving or transmitting
vs. input voltage and RF power output. Duty cycle is a function of how many time slots of the 8 per
second are used for transmission. The STFP protocol used by the communications manager to send
data into the radio for transmission over the air specifies what time slot to use for each, so if the
communications manager uses all 8 slots, the duty cycle is 100%. If four are used every second, the
duty cycle is 50%. If 7 are used every 3 seconds (24 slots), the duty cycle is 29% (roughly 30%).
Many other duty cycles are possible depending on the epoch size and number of transmissions
within each epoch. If the duty cycle exceeds 29%, the RF output power is limited to 2 Watts. All MPE
RF safety calculations are based on the highest ERP levels.

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.
Select the frequency for the test transmission.
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.
Select the Force TX Key menu option.
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.

Enter the IP address of a known node on the network.
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:
 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.

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.
Ensure you have a license to operate the radios and in the configuration settings below,
ensure the frequency setting matches your license.
Run the Poller application on a PC at the fixed base location, setting it up according to the
screen shots below.
Once the Base Radio is set up properly, start polling.
Notes: Set the IP address to that of the Base Radio. Set “GPS Serial Port” to “None” to prevent the
base Poller from attempting to open communications with a GPS receiver. You can set the Receive
on IP Port to any value, because the base Poller will transmit only.
05-6906A01
Page 18 of 49
7/31/2014
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.
05-6906A01
Page 19 of 49
7/31/2014
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.

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.
Set up the mobile Poller application as shown in the following screen shots.
When you start the test from the Mobile Poller application, use the “Start Receiving” button
instead of the “Start Polling” button. This puts the utility into receive-only mode.
Notes: You should set the mobile Poller to send to the portable PC’s IP address (or 127.0.0.1) and
an unused port like 55555 because the mobile radio is not intended to transmit for this test. Set
the mobile Poller to log to the desired file. This file will contain your survey data including date,
time, GPS location and received signal strength. Set the Poller application to accept GPS NMEA
data from a GPS receiver via the appropriate serial port and mode.

Description
The timing source used by the radio to precisely determine
current time and the start of each second. Valid values are Global
Positioning System (GPS), Precision Time Protocol (PTP), GPS with
PTP fallback, PTP with GPS fallback, and over-the-air (OTA). Base
radios are configured for GPS, PTP, GPS with PTP fallback, or PTP
with GPS fallback. Mobile radios are configured for OTA. An OTA
radio requires either a GPS or PTP radio within range in order to
synchronize timing.
Uniquely identifies the radio to the Communication Manager.
This IP Port is used to receive STFP messages from the
Communication Manager.
This is the IP Address of the Communication Manager.
This is the IP Port used by the Communication Manager to receive
STFP messages from the radio.
This is the number of seconds constituting an epoch. Valid values
are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30. The number of timeslots
equals 8 times the epoch size chosen. Note: This parameter must
match for all radios communicating.
This is the number of slots (125ms each) in advance that the radio
will request data from the Communication Manager. This delay
encompasses the time needed for timing markers to transit the
network, processing by the Communication Manager, and
resulting payload messages to transit the network.
This parameter requests the radio to transmit beacons in the first
time slot of each second when no message is received from the
Communication Manager for the time slot. Beacons are required
to maintain OTA timing of mobiles. Note: This parameter is
ignored and no beacons are sent when the timing source is set
to OTA.
If the selected timing input is missing for this duration, the radio

The RF Output Power from 2 to 25 Watts with which the radio
transmits. Note: STFP messages specify the power to be used
when transmitting. This parameter is ignored once an STFP
message has been received.
If enabled the radio ignores per message power values specified
by STFP and forces transmissions at a lower power level suitable
for driving the external PA (around 200 mW).
The maximum age a transmit message can remain in the queue
before it is dropped. This time is measured from when the
message is received via UDP until it is about to be placed into a
packet for transmission OTA.
“Normal” to allow the radio to operate in data mode, “Forced” to
key the transmitter for test purposes.
If TX Key is Forced, the radio will automatically De-Key after this
timeout.

6 Troubleshooting
Here are some tips to help resolve issues when operating the TD220X.
Symptom
Radio is alarmed (PWR LED is flashing)
Alarm: GPS PPS Not Available
Alarm: GPS Signal Inverted
Alarm: NMEA Data – Invalid
Alarm: OTA Sync Lost
Alarm: PTP Sync Lost
Radio shows messages are received via
Ethernet, but it will not transmit over the air.
05-6906A01
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).
The radio has lost over the air synchronization
because it is no longer receiving wireless
beacons from a GPS or PTP radio.
The radio is not receiving time updates from the
configured PTP Grandmaster Clock.
Radio is alarmed.
