FCC: PJL60020-2 1.0 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. Figure 1-Class A/B Reader Functional Block Diagram FCC: PJL60020-2 2.0 Reader Controls and Indicators 2.1 Reader Power Indicator A green LED on the front panel of the Reader is lit when the Reader is powered ON. 2.2 Reader Power Switch A rocker switch on the front panel of the Reader is used to power the Reader ON and OFF. 2.3 Vehicle-to-Roadside Communications (VRC) Card DIP Switch U112 Configuration The configuration for DIP Switch U112 on the VRC Card is illustrated in Table 1.

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. FCC: PJL60020-2 2.7 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. 2.8 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. FCC: PJL60020-2 3.0 Reader Operation Using HD Version 5.0 3.1 Required Equipment 3.1.1 Host Driver (HD) Version 5.0 Test program designed to simulate a Reader host system. 3.1.2 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. 3.1.3 Serial Cable DB-9 Female to DB-9 Male RS-232 serial adapter cable used to connect the Reader and the PC. 3.1.4 +12V DC Power Supply Used to provide power to the Reader. A minimum rating of 3.5A is required. FCC: PJL60020-2 3.2 Reader Operation Procedure Using HD Version 5.0 3.2.1 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 3.2.2 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 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 <Ctrl>, and press <Enter> to change the Internal Configuration.

Refer to 2.1047 for test data. 2.1033 (c) (14)Test Data Refer to 2.1046 through 2.1057 2.1046Measurement of RF Power Output Definition:Power output shall be measured at the RF output terminals when the transmitter is adjusted in accordance with the tune-up procedure to give the values of current and voltage on the circuit elements. Test Method: Power measurements were recorded using the test setup shown in Figure 1. Test Results: Power was verified to not exceed 30 dBm (1 Watt). The measured power was 29.95 dBm (CW) and 18.03 dBm (ASK) at a nominal supply voltage of 13.8 Vdc. The power output did not change when the voltage was increased to 115% of nominal (15.9 Vdc).

Manchester data encoding: A logic 0 is encoded as low for the first half of the bit interval and high for the second half; a logic 1 is represented as high for the first half of the bit interval and low for the second half. ASK modulation: the transmitter switches on for a “high,” and off for a “low.” Test Method: Connect the Equipment per Figure 2. Observe the Reader’s transmitter output using the Oscilloscope and diode detector. Verify the Amplitude Shift Keying, Manchester coding, and data rate by observing the detected transmitter waveforms. Test Results: See Figure 3 (photographs) and Figure 4. The first plot shows one transmit frame, which has a duration of 9.8 msec. The second plot shows a magnification of the first 20 microseconds of the extended header of a frame control message. The ASK modulation characteristic (Table 1, Item 8) is evident: the detected signal switches on for a “high,” and off for a “low.” The third plot shows an expanded view of a 16-microsecond frame sync pulse. The digital representation of the sync pulse is 8D hex or 10001101 binary. This figure shows the appropriate Manchester coding (Table 1, Item 9). The 500 Kbps data rate (Table 1, Item 10) is also evident in this plot; each bit interval (Manchester high/low or low/high) occupies 2 microseconds.

C. when compared to the frequency measured at laboratory ambient temperature following a 30-minute stabilization period. The nominal frequency of the EUT is 918 MHz. A frequency accuracy of 275 ppm equates to a frequency “drift” of plus or minus 252.45 kHz at this frequency. FCC ID: PJL60020-2 Figure 8: Block Diagram – Frequency Stability ____________________________________ __________ Test Method: 1. Set-up the equipment according to Figure 8. 2. Configure the reader to operate in the CW mode. The transmitter can be toggled on and off by using the mute (F12) control. To turn off the RF output and place the transmitter in a mute mode, press the F12 button. Press F12 again to turn it back on. 3. Allow equipment to operate for a period of at least 30 minutes at room temperature. 4. While the equipment is at 20 degrees C, turn on the transmitter and record the frequency on the frequency counter. 5. Calculate the lower and upper frequency limit s and record in Table 1. 6. Reduce the temperature of the chamber to -30 deg. C. 7. As soon as the equipment has reached the desired temperature (allow sufficient time to soak), operate the transmitter and record the frequency on Table 1. 8.
