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
transponder’s data package to the next appropriate station (dependent of the type of system connected to
the Reader). The Reader’s functional block diagram, shown in Figure 1, illustrates the interconnections
between the assemblies in the Reader’s sealed chassis.

VRC Card Reset Indicator
The red LED (DS1) on the VRC Card lights for approximately 1-2 seconds, then remains OFF when the
reset switch (S100) on the VRC Card is pressed, or when the Reader is powered ON.
3.5
Reset Switch
The microprocessor (U100) on the VRC Card is reset when the reset switch on the VRC Card (S100) is
pressed.
3.6
Squelch Adjustment Potentiometer R13
Potentiometer R13 (closest to the DB-37 connector) on the VRC Card is used to adjust the sensitivity and
communication range of the Reader. 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.

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.

4.1.1
Required Equipment
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.

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 , and press . This will bring up HD’s 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 , and press  to change the Internal Configuration.

Turn the Reader power switch to the ON position.
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 Reader’s 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 HD’s Internal Configuration menu, and also verify that the green LED on
the Reader’s front panel is illuminated.
4.2.5
•
Checking Reader Status
Communication between the Reader and HD can be checked by pressing  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
•
Powering on the Reader
Resetting the VRC Card
The VRC Card can be reset at anytime by pressing  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.

Changing the Reader’s Communication Mode
Normal and Mute mode are two of the Reader’s communication modes that are useful for this
implementation of the Reader. Normal mode is the Reader’s normal modulated mode of operation. Mute
mode places the Reader’s 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 HD’s Internal Configuration menu) configure the Reader. The default parameters for HD
5.0 are listed in Appendix A.
• To change the Reader’s communication mode, press  from within HD. This will bring up HD’s
Configuration Parameters menu shown in Figure 6.
• Change the “Comm Mode” field to change the Reader’s communication mode.
0 = Normal Mode
3 = Mute Mode
• Hold down  and press  to change the Reader’s Configuration Parameters.

Changing the Reader’s Antenna Switching Pattern
Only one of the Reader’s antenna ports can be active at one time. 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 Reader’s antenna pattern, press  from within HD. This will bring up HD’s
Configuration Parameters menu shown in Figure 6.
• Change the “Antenna Pattern” field to change the Reader’s antenna pattern.
Examples
10000000 = Antenna 1 Only
20000000 = Antenna 2 Only
30000000 = Antenna 3 Only
40000000 = Antenna 4 Only
12000000 = 121212…
12300000 = 123123123…
