Page 7: Introduction
1.0 INTRODUCTION This manual is for users of the MDS TD220MAX Transceiver shown in Figure 1. It contains an overview of installation planning data, specifications, troubleshooting, and instructions for using the radio’s menu system. This manual is intended for technical personnel who perform network design, configuration, and troubleshooting of the equipment. -
Page 8: Accessories And Spares
Accessories and Spares Table 1 lists common accessories and spare items for the transceiver. Table 1. Accessories & Spare Items Accessory Description Part Number DIN Rail Mounting Bracket Kit Contains bracket for mounting the transceiver 03-4125A04 to standard 35 mm DIN rails commonly used in equipment cabinets and panels. -
Page 9: Product Description
2.0 PRODUCT DESCRIPTION The GE MDS TD220MAX 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. -
Page 10: Installation Planning
3.0 INSTALLATION PLANNING This section covers pre-installation factors that should be considered when installing the transceiver in the field. Careful planning will help achieve optimal performance from the transceiver. The specific details at an installation site may vary, but there are four main requirements for installing the transceiver in all cases: •... -
Page 11: Optional Din Rail Mounting
The transceiver may be used with several different antennas. The exact style and gain factor depend on the physical size and layout of your system. Connection is made to the radio via a N coaxial connector. Contact your factory representative for details for Antennas available from GE MDS for this radio. Feedlines 3.3.2... -
Page 12: Power
The table which follows, shows the approximate losses that will occur when using various lengths and types of coaxial cable in 200 MHz band. Regardless of the type used, the cable should be kept as short as possible to minimize signal loss. Table 2. -
Page 13: Grounding Considerations
Table 3. Current Consumption vs Input Power and Duty Cycle Voltage (V) RF Power Out (W) Duty Cycle (%) Current Required (A) Thermal Dissipation (W) 0 (RX) 13.8 0 (RX) 13.8 13.8 13.8 Grounding Considerations To minimize the chance of damage to the transceiver and connected equipment, a safety ground (NEC Class 2 compliant) is recommended which bonds the antenna system, transceiver, power supply, and connected data equipment to a single-point ground, keeping all ground leads as short as possible. -
Page 14: Adapter Board
Adapter Board 3.6.1 GE MDS has available a breakout adapter board that separates the DB25 connector into an Ethernet port, PPS port, as well as three COM connectors. This board is for controlled environment applications only. For additional details regarding the adapter board, view the “TD_RCL” adapter board instruction sheet located here http://www.gegridsolutions.com/app/resources.aspx?prod=td-series&type=9. -
Page 15: 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. -
Page 16: Antenna Connector
Antenna Connector The Antenna Connector is a type N female connector with 50-Ohm characteristic impedance. A suitable lightning arrestor such as a Polyphaser VHF50HN should be employed when indicated by applicable standards or codes. TD220MAX Technical Manual MDS 05-6906A01, Rev R... -
Page 17: Step-By-Step Installation
4.0 STEP-BY-STEP INSTALLATION In most cases, the steps given here are sufficient to install the transceiver. 1. Mount the transceiver. Attach the mounting brackets to the bottom of the transceiver case (if not already installed), using the four 6-32 x 1/4-inch (6 mm) screws supplied. Mounting bracket dimensions are shown in Figure 5 on Page 5. -
Page 18: Telnet Console
Telnet Console 4.1.2 NOTE It is not recommended to change the default IP settings via the Telnet interface. Networking changes should be done locally via the serial console and then deployed in the field. See the section above on modifying these networking parameters. On newer computers, the default telnet function on Windows machines may be disabled. -

Set Up an OTA Mobile Unit 1. Log in to the radio. 2. Go to the System Configuration Menu. 3. Set the timing source to OTA and allow the radio to reboot (factory-new units default to OTA, so this step may be skipped). 4. -
Page 22: Menu Interface
5.0 Menu Interface The menu interface can be reached via two ways; serially via the DB25 connector or by Telnet via the Ethernet Interface. This section will describe the different menus available on the radio. Configurable settings are followed by information in brackets. The information includes a comma- separated list of possible values then a semicolon and the default value. -
