This manual describes each entity of the radio assemblies in detail. It provides the necessary information for qualified technical personnel to install, repair, and maintain the MDR and BDR assemblies to the line replaceable unit (LRU). This manual is divided into six chapters, which consist of sections to describe the information or procedures in detail. The six chapters are as follows: 1.2 • Chapter 1 outlines the contents of this manual and provides a basic equipment description of the MDR and BDR. • Chapter 2 provides preparation for use and installation information. • Chapter 3 provides operating procedures for the equipment. • Chapter 4 provides the principles of operation. • Chapter 5 provides preventive and corrective maintenance of the radio assemblies. • Chapter 6 contains a vendor list and parts list for procurement of replacement parts. • Chapter 7 contains mechanical outlines of the data radios. PREPARATION FOR STORAGE OR SHIPMENT The following paragraphs describe guidelines for long term storage and the shipment of the equipment. 1.2.1 STORAGE Before storage, wrap the equipment in static shielding bubble wrap. Bubble wrap protects internal electrostatic discharge sensitive (ESDS) assemblies, external panels, and connectors. Place wrapped equipment in the original shipping containers and seal. Store in a cool dry place, away from the elements. 1.2.2 SHIPMENT Ship equipment in the original shipping containers or in a container that provides sufficient protection for ESDS equipment. Pack the equipment in a manner that provides protection for all external switches and mountings, because these items are most vulnerable to damage during shipment. Document use is restricted to that described on cover 1-1 385700-1006-006 1.3 INSTALLATION DESCRIPTION OF EQUIPMENT The Radio Communications Network consists of Base and Mobile Radio Communication Systems (RCS). The Base RCS includes Base Data Radios (BDR) connected to wayside Control Equipment. The Mobile RCS includes Mobile Data Radios connected to Control Equipment on board the vehicle. The Radio Communications Systems provide bi-directional communications. The systems operate in a combined Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) environment. The Mobile Data Radio (MDR) and Base Data Radios (BDR) in the technical manual are Spread Spectrum non-licensed RF transceivers. 1.3.1 TYPE OF EQUIPMENT The MDR and BDR are non-licensed spread spectrum transceivers that operate in the ISM 2400-2483.5 MHz frequency band. Antennas connected to MDR and BDR may come from different vendors. Antennas should support the 2400-2483 MHz frequency band, be compliant with FCC part 15 regulations, and are to be installed by professional parties. Refer to Table 1-1 MDR/BDR Types and Applications. numbers for different versions of MDR and BDR. The following table contains part Part No. 385700-1000-001 385700-1000-002 Type MDR MDR Application Input Voltage 18-32 VDC Input Voltage 21-56 VDC 385700-3000-001 385700-3000-002 385700-3000-003 BDR BDR BDR Rack Mounted Wall Mounted Pole Mounted Table 1-1 MDR/BDR Types and Applications 1.3.2 PURPOSE OF THE EQUIPMENT The radio provides a bi-directional communication link between the wayside and the vehicle control equipment. The wayside control equipment generates data and sends it to the BDR. The BDR transmits data over the radio channel to the appropriate MDR. The MDR communicates with the vehicle control equipment, obtains the response, and transmits it to the BDR via the RF link. 1.4 LOCATIONS AND DESCRIPTIONS OF MAJOR COMPONENTS Refer to Figure 1-1 Mobile and Base Radio Assemblies and Components.

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. An operator can also communicate with the MDR through the diagnostic port across an RS-232 interface (refer to paragraph 2.5.2) at J4. This interface is referred to as the Local Command Processor (LCP) terminal and is used to load user supplied parameters into the radio’s non-volatile memory when the radio is initially delivered to the customer. This RS232 interface is not used during normal operation of the radio. The MDR receives power from a nominal 28 VDC (or a nominal 36 VDC depending on application), power source at J1. Refer to Table 1-2 Mobile Data Radio Assembly Specifications. 1.4.2 BASE STATION RADIO ASSEMBLY The base data radio (BDR), like the MDR, is a spread spectrum transceiver. The BDR transmits at a center frequency of 2416.64 MHz frequency and receives at a center frequency of 2457.84 MHz band. Refer to Table 1-3 Base Station Radio Assembly Specifications. The BDR communicates across an EIA 530 (RS-422) interface to the wayside control equipment at J2 or J3 (see Figure 2-10). An operator can also communicate with the BDR through the diagnostic port, J4, across an RS-232 interface (refer to paragraph 2.5.2). This interface is referred to as the Local Command Processor (LCP) terminal and is used to load user supplied parameters into the radio’s non-volatile memory when the radio is initially delivered to the customer. This RS-232 interface is not used during normal operation of the radio. The BDR receives its AC input power at J1. Tables 1-2 through 1-3 contain the specifications for the MDR and BDR. The tables include characteristics and specifications in three categories: technical, environmental, and physical. Document use is restricted to that described on cover Figure 1-2 Transmitter Block Diagram 1-4 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. 1.5.2 ENVIRONMENTAL INFORMATION The MDR assembly can withstand the shock and vibration associated with mobile environments. It is contained in a weatherproof enclosure. Refer to Table 1-2 Mobile Data Radio Assembly Specifications, for more detailed information. The BDR assembly is designed for an environment away from the elements. It can be rackmounted, or wall mounted.

The regulation defines the allowable Maximum Permissible RF Exposure. In order to meet Maximum Permissible RF Exposure requirements, the user MUST INSURE that the antenna is located based on the following: 1. When the device will be installed with an external antenna (non leaky feeder type)the radiator MUST BE located more than 20 cm from the general public. Document use is restricted to that described on cover 3-7 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. Document use is restricted to that described on cover 3-8 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. The MDR employs both Code Division Multiple Access (CDMA) and Time Division Multiple Access (TDMA) techniques. CDMA is a function of the Pseudo-random Noise (PN) code selected for transmission and reception. The particular technique used in Andrew Base and Mobile Data Radios is Direct Sequence Spread Spectrum (DSSS) technique. In the direct sequence technique, the information spectrum is spread into a bandwidth many times wider than the bandwidth of the data alone by using a pseudorandom noise sequence clocked at a rate significantly greater than the information rate. Each data bit is encoded with a pseudorandom spreading code. The receiver can recover the original data by using the same sequence to decode the encoded data bits. Any other selected pseudorandom sequence simply appears as additional noise at the receiver. When power is applied to a radio, the radio configures the transmit and receiver spreading sequences from data stored in the radio’s nonvolatile memory. After the radio configuration is completed, the Control Equipment can change the spreading sequences. The base station radios and mobile data radios maintain a pool of available PN codes or channels. Each radio requires a code. The transmit and receive codes are different. The receive code of the MDR or BDR must equal the other unit’s transmit code. Adjacent BDRs should not have the same codes. In normal operation, all MDR’s in the same control zone operate with the same set of transmit and receive spreading codes. Time Division Multiple Access techniques are used to minimize interference between the MDR’s. Normally, the BDR keeps its transmitter on all the time. The MDR on the vehicle turns on its transmitters in response to being specifically polled by a BDR. The BDR commands the MDR to bring up its transmitter and send any pending poll responses from the vehicle control equipment. The MDR turns off its transmitter if it fails to get confirmation in a certain period of time that the BDR has “locked” to the MDR. Also, MDR will turn off its transmitter after the BDR successfully “locks” to the MDR transmitter and the MDR sends its response to the BDR. Document use is restricted to that described on cover 4-1 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. The regional control equipment uses a simple roll-call polling technique to communicate with all the vehicles in the region during a communication cycle. When a train approaches a region boundary it is handed over to the next region's radio network by using a software hand-off algorithm. 4.1.2.1 RF TRANSMISSIONS Full duplex operation is achieved by utilizing separate frequency ranges within the 2400 2483.5 MHz band for each direction of communications. Data is transmitted from base radio to mobile using one range and from mobile to base radio over another frequency range. Refer to Table 1-2 Mobile Data Radio Assembly Specifications and Table 1-3 Base Station Radio Assembly Specifications. 4.1.2.2 BASEBAND DATA RATE The radio network operates at a synchronous baud rate of 64Kbps. 4.1.2.3 OSI LAYERS The radio network is developed following the ISO (International Standard Organization) Open Systems Interconnection (OSI) Reference Model. The radio network is modular in design. Industry standard protocol, interfaces and hardware are used to easily interface third party equipment. Figure 4-1 Radio Network OSI Layers Document use is restricted to that described on cover 4-2 385700-1006-006 OPERATIONS Central Control Central Network Wayside Control Equipment Wayside Control Equipment Base Data Radio Base Data Radio Region Region Region-to-Vehicle RF Mobile Data Radio Vehicle Control Equipment Vehicle Figure 4-2 Radio Network Architecture Document use is restricted to that described on cover 4-3 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. 4.1.2.3.2 DATALINK LAYER The data link layer is based on the HDLC (High-level Data Link Control) protocol to communicate over the radio channel between the base Radio Communication System (RCS) and mobile RCS. The same protocol is also used to communicate between the RCS and the control equipment over the EIA-530 interface. A sliding window of one is implemented for the transfer of HDLC Information Frames (I frames). The HDLC Information frame (I frame) format is used to transfer data between the base radio and mobile radio as well as between the radio system and control equipment. The length of a frame is programmable. Currently is set to 81 bytes (including the two flag bytes). The wayside control equipment sends an ATC frame to the radio system along with proper RCS address, control byte and CRC. The first two bytes of the ATC frame will contain the address of the vehicle. This vehicle address will be used by the radio system to address a mobile radio on a vehicle. The control byte determines the type of frame. The radio communication system adds the CRC and flags to the ATC frame and transmits the packet over radio channel. Flag RCS Control Address Byte Communications-Control System Frame Maximum 75 bytes Cyclic Redundancy Flag Check ATC Equipment to Andrew Radio Frame Format Train ID Car ID Region ID Control Byte Communications-Control System Data Maximum 73 Bytes Communications-Control System Frame Format Figure 4-3 SCP to RCS Frame Format A mobile radio is addressed by its two byte Address. Two addresses are reserved. A train address of zero hexadecimal ‘0000’ is not a legal value. The train address hexadecimal ‘FFFF’ is reserved for a broadcast message to all the trains in a region. A broadcast message will automatically be retransmitted by the BDR until the regional control equipment clears the frame. A vehicle will send no response to the broadcast message. Document use is restricted to that described on cover 4-4 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. An MDR responds to a poll only if it is pre-loaded with a response message by the vehicle control equipment. For vehicles with more than one MDR, the vehicle control equipment must direct which MDR will be pre-loaded with a response. Hence, all radio systems in a train receive the message from the region control equipment but only the main radio system sends the response back. Additional information about the message protocol can be found in the referenced ICD document. 4.1.3 MDR/BDR COMMUNICATIONS HANDLING A communications cycle is the exchange of information between the wayside control equipment and each vehicle control equipment within the region. During a typical communications cycle, each vehicle control equipment will be sent a poll request, which will be acknowledged by a poll response from the vehicle control equipment. Each communications cycle is followed by the specific command that clears untransmitted messages before proceeding. The wayside control equipment must query the base data radio every 10 to 20 ms for a poll response, and all poll requests must be sent to the base radio at the beginning of the communications cycle (within the constraints of the protocol). Mobile radios are polled in sequence one after the other in a round robin fashion. The data exchange is based on the High-Level Data Link Control (HDLC) standard protocol to communicate over the radio channel between the Andrew base and mobile radios. The same protocol is also used to communicate between base radio and wayside control equipment and between mobile radio and mobile control equipment over the EIA-530 interface. The handshaking sequence required by the communications protocol precedes each poll response. The referenced Interface Control Document establishes the protocols and interfaces between wayside and vehicle Control Equipment and Mobile and Base Data Radios. 4.1.4 PN SPREADING CODES The Direct Sequence Spread Spectrum and CDMA operation of the radios are controlled by the Pseudo Noise spreading codes contained within the non volatile memory of the radios. Normal operation of the radios requires (1) that the BDR transmit spreading code equal the MDR receive spreading code, (2) that that the MDR transmit spreading code equal the BDR receive spreading code, and (3) that the transmit and receive spreading codes within any radio be different. The radios are configured with over 80 different spreading codes. Selection of the codes by the user-supplied equipment is covered in the Radio Communication System Interface Control Document. Selection of the codes from the LCP terminal is covered in Chapter 8. Document use is restricted to that described on cover 4-5 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. The software control of the antenna select lines is defined in the Radio Communication System Interface Control Document. The MDR Data 2 Port also provides a power and power return path, see MDR Data 2 Port Pin-outs, to the user. The power signal, RADIO PWR, is taken directly from the user supplied input source. The electrical path is made with 22-gauge wire. The user is responsible to insure that (1) the current draw is within the limits that this gauge wire can support and (2) that the user supplied DC power source can supply this current load as well as the current load required by the MDR.

A WYSE 100 compatible terminal or a computer running a terminal emulation program is attached to the diagnostic port. This terminal or computer is referred to as the LCP terminal elsewhere in this manual. The LCP diagnostics menu for the MDR and BDR are identical except for a few commands. The differences are noted in the following sections. The diagnostics menu includes user available selections as well as reserved commands for testing the radio. The reserved commands are intended for use by factory trained personnel only. Use of these commands by unauthorized personnel will require the user to perform a power reset to the unit before normal operation can occur. The following sections are based on a typical LCP menu. The user should contact the factory for updates. The operator selects a particular command by typing the command number, which appears to the left of the command, followed by pressing the ENTER (↵) key. If the command requires additional parameters, the LCP program will prompt the user for inputs. All inputs are completed using the ENTER (↵) key.

Send Poll Requests BDR This command causes the BDR to send or stop sending poll requests to an MDR. The poll request is sent to Vehicle Address 100016. The poll requests are sent at an approximate rate of one request per second. The LCP displays the current state of the polling after this command is entered. The polling state toggles between sending and stopping poll requests each time the command is entered. Vehicle Addr. (Train ID) MDR This command is used to set the 16 bit address of an MDR. Each MDR requires a unique vehicle address. The allowable address range is 000116 to FFFE16 . The address, FFFF16, is reserved for the Broadcast message. Document use is restricted to that described on cover 8-3 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. At the completion of this command, the selected PN generator(s) are reset, the new initial conditions are loaded into the PN generator(s), and the radio displays the new generator PN index. Program Synthesizers BDR and MDR This command is reserved for future use or internal unit testing. Reserved BDR and MDR This command is reserved for future use or internal unit testing. Reset DSP BDR and MDR This command is reserved for future use or internal unit testing. Reset PN BDR and MDR This command allows the user to start one of the PN sequences in the radio at a known state. The user is prompted for the type of generator reset (continuous, pulsed, or release from continuous) and which generator, Tx or Rx, to reset.. Reset PN (RX STROBE) This command performs a pulsed reset of the Rx PN generator with a double keystroke entry by the user. SET UPPER THRESHOLD BDR and MDR The upper threshold value is part of the radio receiver’s confidence test for determining PN code synchronization. The UPPER THRESHOLD must be greater than the LOWER and LOWER LOCK thresholds. The actual values used are set at the factory. Large values for the upper threshold require input high signal levels. If the levels are set too high, the radio will not be able to declare PN synchronization. If the levels are set too low, the radio will falsely declare PN synchronization. This will degrade communications throughput by increasing the amount of time to synchronize to the incoming PN code. Using this command results in an internal radio receiver reset condition. This forces a radio receiver to reacquire PN synchronization. The range of allowable values is 0016 to FF16 subject to the above stated requirements. UPPER THRES W/O PN RESET BDR and MDR This command is similar to the Set Upper Threshold command except it does not force the radio receiver to reacquire PN synchronization after the new threshold is loaded. SET LOWER THRESHOLD BDR and MDR The lower threshold value is part of the radio receiver’s confidence test for determining PN code synchronization. The LOWER THRESHOLD must be less than the UPPER THRESHOLD but greater than the LOWER LOCK thresholds. The actual values used are set at the factory. Large values for the lower threshold require input high signal levels. If the levels are set too high, the radio will not be able to declare PN synchronization. If the levels are set too low, the radio will falsely declare PN Document use is restricted to that described on cover 8-4 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. LOWER THRES W/O PN RESET BDR and MDR This command is similar to the Set Lower Threshold command except it does not force the radio receiver to reacquire PN synchronization after the new threshold is loaded. SET LOWER LOCK THRESHOLD BDR and MDR The lower threshold value is part of the radio receiver’s confidence test for maintaining PN code synchronization. The LOWER LOCK THRESHOLD must be less than the UPPER THRESHOLD and is normally less than the LOWER LOCK thresholds. The actual values used are set at the factory. Large values for the lower threshold require input high signal levels. If the levels are set too high, the radio will not be able to maintain PN synchronization. If the levels are set too low, the radio will falsely maintain PN synchronization. This will degrade communications throughput by increasing the amount of time to correctly 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. DISABLE TRANSMITTER BDR and MDR This command allows the user to manually turn off the radio transmitter. ENABLE TRANSMITTER BDR and MDR This command allows the user to manually turn on the radio transmitter. If the radio has not been powered down, the output level will be the last loaded value. If the radio is powered down after selecting this command, the output level will be the last value saved to non volatile memory. The user can check the level with the STATUS REQUEST command. The user can change the output level with the SET dBm OUTPUT LEVEL command. LOAD SC REGISTER BDR and MDR This command is reserved for future use or internal unit testing. DISABLE TEST PORT BDR and MDR This command is reserved for future use or internal unit testing. PN TEST SELECT BDR and MDR This command is reserved for future use or internal unit testing. A/D SELECT BDR and MDR This command is reserved for future use or internal unit testing. SET CLOCK SEARCH BDR and MDR This command is reserved for future use or internal unit testing. Document use is restricted to that described on cover 8-5 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. SSR STATUS REQUEST BDR and MDR This command reads the current configuration data stored inside various modules within the radio. It includes a display that indicates whether the data agrees with the data originally written to the modules. The parameters currently supported are the lower lock, lower, and upper thresholds, the Tx and Rx PN code, the Tx and Rx Data Rates, and the current state of the Transmitter. All other parameters are for future use. STATUS REQUEST BDR and MDR This command displays the current radio configuration as stored in the radio’s volatile memory. The parameters currently supported are the lower lock, lower, and upper thresholds, the Tx and Rx PN code, the Tx and Rx Data Rates, and the current state of the Transmitter. All other parameters are for future use. SHOW POLL COUNTERS BDR This command displays a group of communication counters that monitor the polling activity between the BDR and MDR and special flags used for internal radio code debugging. The counter types currently supported are the number of poll requests input to the BDR, the number of frames transmitted from the BDR controller to the radio RF transmitter, the number of valid poll responses received from the MDR, the total number of frames received from the radio RF port at the BDR controller, and the number of poll request retransmission attempts. CLEAR POLL COUNTERS This command zeroes a group of communication counters that monitor the polling activity between the BDR and MDR. READ TRACK/AGC VALUES BDR and MDR This command is reserved for future use or internal unit testing. SET dBM OUTPUT LEVEL BDR and MDR This command is used to set the transmitter output power level of the radio. The range of listed output levels may be greater than the specifications of the radio. When using this command, the user must set the output level such that compliance with FCC output level requirements are maintained. The output resolution is in 1 dB increments. CHANGE dBM/DAC VALUES BDR and MDR This command is reserved for factory calibration or internal unit testing. The command, Set dBM Output Level, is used to enter the PA control voltages corresponding to an RF output levels. After entering the voltage/ RF levels, the user Document use is restricted to that described on cover 8-6 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. LOAD TND SC REGISTER BDR and MDR This command is reserved for future use or internal unit testing. TOGGLE TEMP COMPENSATION BDR and MDR This command is reserved for future use or internal unit testing. DISPLAY SYSTEM LOG BDR and MDR This command is reserved for future use or internal unit testing. Read Track BDR and MDR This command is reserved for future use or internal unit testing. Read AGC BDR and MDR This command is reserved for future use or internal unit testing. Power BDR and MDR This command is reserved for future use or internal unit testing. Test EEPROM BDR and MDR This command performs a non destructive test of the EEprom circuitry. Read PA/Temp BDR and MDR This command is reserved for future use or internal unit testing. Poll Response MDR This command toggles the MDR poll response state between enabling and disabling a fixed command response. Enabling the fixed poll response configures the radio to transmit an 81 byte message whenever the MDR receives a valid poll request from the BDR. Document use is restricted to that described on cover 8-7 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 ANTn line selected ANT0 ANT1 ANT2 Unused BDR and MDR This command is reserved for future use or internal unit testing.
