(HD) Version 5.0 as the host. 1.3 Definitions, Abbreviations, & Acronyms DSRC HD PC REM RF VRC Dedicated Short Range Communications Host Driver Personal Computer Range Extension Module Radio Frequency Vehicle to Roadside Communications RAYTHEON PROPRIETARY A6 27 March, 2001 FCC ID: PJL60020-2 DSRC Reader Description and Operational Procedure Version: Draft 2.0 Reader Description The Reader is an automatic vehicle identification systems that transmits and receives radio frequency
(RF) data to/from transponder-equipped vehicles or assemblies. The Reader works in conjunction with a host computer system to identify a passing transponder, verify its operating credentials (if applicable), communicate to the driver whether the vehicle is cleared or not (if applicable), and transmit the transponders data package to the next appropriate station (dependent of the type of system connected to the Reader). The Readers functional block diagram, shown in Figure 1, illustrates the interconnections between the assemblies in the Readers sealed chassis.

When the potentiometer adjustment screw is turned clockwise, the Reader is more sensitive to transponders and the communication range increases. When the potentiometer adjustment screw is turned counterclockwise, the Reader is less sensitive to transponders and the communication range decreases. This potentiometer adjustment should only be performed by qualified, trained technicians. RAYTHEON PROPRIETARY A8 27 March, 2001 FCC ID: PJL60020-2 DSRC Reader Description and Operational Procedure Version: Draft 3.7 VRC Card Drive Adjustment Potentiometer R41 Potentiometer R41 (furthest from the DB-37 connector) on the VRC Card is to be used only by a qualified technician to adjust the transmit power output drive level of the VRC Card. Clockwise rotation of the potentiometer adjustment screw increases the transmit power drive; counterclockwise rotation decreases the transmit power drive. NOTE: The Reader output power should not be adjusted using this method. See section 3.8 for correct output power adjustment. 3.8 Reader Transmit Output Power Adjustment Potentiometer R5 on the REM is to be used only by a qualified technician to adjust the transmit output power output level of the Reader. Clockwise rotation of the potentiometer adjustment screw increases the transmit power level output; counterclockwise rotation decreases the transmit power level output. RAYTHEON PROPRIETARY A9 27 March, 2001 FCC ID: PJL60020-2 DSRC Reader Description and Operational Procedure Version: Draft 4.0 Reader Operation Using HD Version 5.0 4.1 Required Equipment 4.1.1 Host Driver (HD) Version 5.0 Test program designed to simulate a Reader host system. 4.1.2 PC (Host Computer) (486 or better) Used to run HD Version 5.0. Interface to the Reader is to be either RS-232, or RS-422, which would require an RS-422 to RS-232 adapter between the Host Computer and the Reader. When the interface is selected to be RS-232, the PC is connected to the Test Port (RS-232) port. When the interface is selected to be RS-422, the PC is connected to an RS-232-to-RS-422 converter, and the converter is connected to the Host Data (RS-422) port. 4.1.3 Serial Cable DB-9 Female to DB-9 Male RS-232 serial adapter cable used to connect the Reader and the PC. 4.1.4 +12V DC Power Supply Used to provide power to the Reader. A minimum rating of 3.5A is required. RAYTHEON PROPRIETARY A10 27 March, 2001 FCC ID: PJL60020-2 DSRC Reader Description and Operational Procedure Version: Draft 4.2 Reader Operation Procedure Using HD Version 5.0 4.2.1 Connecting the System Turn the Reader Power switch to the OFF position. Connect the system per Figure 2. Figure 2-Reader Operational Setup Using HD Version 5.0 4.2.2 Configuring HD Version 5.0 Run HD 5.0 (HD50.exe) on the PC. Figure 3 is a screenshot of the HD Version 5.0 application upon startup. Within HD 5.0, hold down <Shift>, and press <F3>. This will bring up HDs Internal Configuration menu shown in Figure 4. In the field VRC Com Port (1-4), enter the number of the serial port that HD will be using to communicate with the Reader. Verify that the field VRC Baud (9600, 38400, 57600, 115200) is set to 115200. Hold down <Ctrl>, and press <Enter> to change the Internal Configuration.

Verify successful communication between the Reader and HD by observing the lines Fault Report:
Need Config, followed by Cmd Accepted as displayed within HD. Fault Report: Need Config is the result of the Reader alerting the host that is has not been configured. Cmd Accepted is the result of the Readers acknowledgement to the configuration automatically sent to the Reader by HD. If successful communication between the Reader and HD is not observed, verify that the correct com port and baud rate are set in HDs Internal Configuration menu, and also verify that the green LED on the Readers front panel is illuminated. 4.2.5 Checking Reader Status Communication between the Reader and HD can be checked by pressing <F5> from within HD. This will request the Reader to send a status report to HD. A successfully received status report is shown in Figure 5. 4.2.6 Resetting the VRC Card The VRC Card can be reset at anytime by pressing <F1> from within HD. Fault Report: Need Config, followed by Cmd Accepted should be displayed within HD to indicate a successful restart of the VRC Card.

Normal mode is the Readers normal modulated mode of operation. Mute mode places the Readers transmitter is a disabled state. The Reader starts up in Mute mode and will remain in this mode until it is successfully configured. When the Reader is powered ON and is informing the host that it is not configured, HD will automatically (depending on the state of the Config Auto Response in HDs Internal Configuration menu) configure the Reader. The default parameters for HD 5.0 are listed in Appendix A. To change the Readers communication mode, press <F2> from within HD. This will bring up HDs Configuration Parameters menu shown in Figure 6. Change the Comm Mode field to change the Readers communication mode. 0 = Normal Mode 3 = Mute Mode Hold down <Ctrl> and press <Enter> to change the Readers Configuration Parameters.

The antenna ports are switched on a frame-by-frame basis according to a configurable 8-digit antenna pattern. The antenna pattern can be set with the values 0-4, where 0 indicates the end of the pattern, and 1-4 are antenna numbers. To change the Readers antenna pattern, press <F2> from within HD. This will bring up HDs Configuration Parameters menu shown in Figure 6. Change the Antenna Pattern field to change the Readers antenna pattern.
