385700-1006-006 1.4.1 INSTALLATION MOBILE DATA RADIO ASSEMBLY The mobile data radio (MDR) uses direct sequence spread spectrum modulation techniques. The MDR transmits at a center frequency of 2467.84 MHz. and receives at a center frequency of 2416.64 MHz. The MDR communicates with the vehicle control equipment across an EIA 530 (RS-422) interface at J2. The MDR can also send messages to external equipment via an RS-232 interface at J3.
385700-1006-006 1.5 1.5.1 INSTALLATION EQUIPMENT CHARACTERISTICS POWER AND UTILITY REQUIREMENTS The MDR requires a nominal 28 VDC (or a nominal 36 VDC depending on application) power source to operate. Refer to Table 1-2 Mobile Data Radio Assembly Specifications for more detailed information. The BDR requires nominally 120 VAC to operate. Refer to Table 1-3 Base Station Radio Assembly Specifications, for more detailed information. 1.5.

385700-1006-006 3.3 OPERATIONS OUTPUT POWER SETTINGS The Base Data Radio and Mobile Data Radios are unlicensed devices operating under the conditions of FCC part 15 regulations. This equipment is intended to be installed and operated by professional parties. It is the responsibility of those parties to insure that the equipment is operated in compliance with the applicable FCC part 15 specifications. The transmitter output power setting is set at the factory.
385700-1006-006 OPERATIONS 2. When the device is installed with leaky feader cable the nominal measured radiated field at 3 meters is 65.2 dBuV/m which relates to 1 microwatt E.I.R.P. Although these levels would allow for closer that 20 cm spacing, it is recommended that the cable be located at a minimum 20 cm separation between the radiator and the general public.
385700-1006-006 OPERATIONS CHAPTER 4 PRINCIPLES OF OPERATION 4.1 4.1.1 FUNCTIONAL DESCRIPTION OF EQUIPMENT MOBILE DATA RADIO AND BASE DATA RADIO The BDR and MDR are full duplex transceivers that operate as intentional radiators in the FCC's 2400-2483.5 MHz industrial, scientific, and medical (ISM) band in North America and within 2400-2500 MHz international band. They operate as unlicensed devices and are compliant to the applicable FCC part 15 regulations.
385700-1006-006 4.1.2 OPERATIONS RADIO NETWORK ARCHITECTURE The typical communication flow consists of wayside equipment (user control equipment and BDRs) communicating with mobile equipment (user control equipment and MDRs). Wayside to mobile communication can be distributed over a single or a number of radio networks. Each control region is considered as a single radio network.

385700-1006-006 4.1.2.3.1 OPERATIONS PHYSICAL LAYER The physical layer is composed of a synchronous serial interface between the control equipment and the base or mobile transceiver and a radio to radio link based on spread spectrum technology. The baseband interfaces are based on the EIA-530 interface. The RF radio link is based on Direct Sequence Spread Spectrum modulation. 4.1.2.3.
385700-1006-006 OPERATIONS The radio communication system at the receiving end receives the packet and passes it to the vehicle control equipment. The successful receipt of an I frame must be acknowledged by the receiving RCS and control equipment. This is done by incrementing the Nr field of the control byte within the next frame sent. If a vehicle has more than one radio communications system, one of them acts as the main unit and the others act as auxiliary radios.
385700-1006-006 4.1.5 OPERATIONS ANTENNA SWITCHING CONTROLS The MDR Data 2 Port includes 3 signals, see MDR Data 2 Port Pin-outs, that can provide 20 ma of drive current. The current based signals, ANT0-ANT2, can be connected to a user supplied external switch that controls a multiple antenna configuration that is connected to the MDR. The return current path signals, SIGA GND, are tied together inside the radio.
385700-1006-006 MAINTENANCE AND TROUBLESHOOTING CHAPTER 5 MAINTENANCE AND TROUBLESHOOTING 5.1 PREVENTIVE MAINTENANCE, INSPECTION, AND CLEANING This section describes preventive maintenance procedures for the MDR and BDR assemblies.

385700-1006-006 DIAGNOSTIC LCP MENU Set PN Index (CDMA Code) BDR and MDR This command selects the spreading code to be used by the Transmitter and Receiver PN spreading generators. The user selects the generator(s), Tx, Rx, or Both to be loaded, and an index number which points to a lookup table of PN generator initial conditions.
385700-1006-006 DIAGNOSTIC LCP MENU synchronization. This will degrade communications throughput by increasing the amount of time to synchronize to the incoming PN code or by preventing PN code synchronization altogether. Using this command results in an internal radio receiver reset condition, which forces a radio receiver resynchronization. The range of allowable values is 0016 to FF16 subject to the above stated requirements.
385700-1006-006 DIAGNOSTIC LCP MENU OS-9 SHELL BDR and MDR This command is reserved for future use or internal unit testing. The ESCAPE key is used to return the radio to its normal operating condition from this state. SET RCS ADDRESS BDR This command sets the BDR address. It is used in multiple BDR configurations. The allowable range of address is 0116 to FE16. A default address of 4016 is preloaded into the BDR upon power up initialization. See the ICD for further information.
385700-1006-006 DIAGNOSTIC LCP MENU must save the entries to non volatile memory using the SAVE CURRENT SETTINGS command. SERIAL EEPROM DISPLAY BDR and MDR This command displays the radio configuration parameters stored in the non volatile memory of the radio. These are the parameters loaded into the radio upon applying power to the unit. SAVE CURRENT SETTINGS BDR and MDR This command writes the current radio configuration parameters to the non volatile memory of the radio.
385700-1006-006 DIAGNOSTIC LCP MENU Select Antenna MDR This command sends a binary encoded value to the ANTn lines of the MDR Data 2 port. The ANTn lines are 20 ma driver control lines. The truth table for selecting the ANTn lies is given below: Select Antenna Value 1 4 8 ANTn line selected ANT0 ANT1 ANT2 Unused BDR and MDR This command is reserved for future use or internal unit testing. Read Memory BDR and MDR This command is reserved for future use or internal unit testing.
