Bagdons James Mason product Model: J.M.A. Computer & Wireless Auto Measuring System OPERATION DESCRIPTION: This device consists of two parts: 1) TRAM assembly, and 2) Transmitter box attached to a computer. The function of this device is to compare dimensions of a vehicle from after a vehicle repair to the original dimensions from the factory. This device (TRAM) is placed on the repaired vehicle and when desired, a push button switch on the TRAM part of the device is pressed and this transmits measured data from the TRAM to the identical transceiver in the Transmitter box which is connected to the computer. This information is then recorded in the computer. Both ends of the device (TRAM and Transmitter box) contain identical transmitter and receiver units. The device operates on the frequency of 916 Mhz and is pulse modulated. The maximum length of a transmitted burst is 190 mS. A typical message is considerably shorter. During periods of no activity, the communication is constantly looking for a complete communication circuit by polling with ACK’s , NAK’s which are 20 mS bursts of signal. A poll message is sent from the PC side (Transmitter box). If the remote unit (TRAM) has anything to transmit (New measurement), a data message is transmitted back. If there are no new measurements, the remote unit will not reply. ACK or NAK messages are sent in reply to data messages. Microprocessors, on both sides, control the data transmission. A Data buffer in the microprocessor (internal RAM) holds the message data. All messages are fixed length. There are two modes of operation for the system: • Idle mode - No radio transmissions, so we can ignore this mode of operation. • Recording mode - In the recording mode, system is transmitting "data messages" (all data messages are always 190ms) and "control messages" (all control messages POLL and ACK are always 20ms). The length of these messages is controlled by micro FW on both sides (PC and black box side). There are three possible situations in the recording mode: • PC side needs to send data to the black box (operator is starting or stopping the recording mode of operation). In this situation, instead of sending a regular POLL control message, PC side sends a data message (190ms) to the black box. If this message is received by the black box, it will reply with ACK control message. When PC side receives this ACK control message, this instance of data transfer from PC to the black box is completed and regular POLL control messages will resume, but only after another 800ms delay. • Black box needs to send data to the PC (operator has pressed transmit button on the black box). Black box will wait for the POLL control message from the PC side. When this POLL control message is received, black box will send back the data message (190ms). Upon receiving this data message, PC side will send back ACK control message to the black box. This completes the data transfer from black box to the PC side. The next POLL control message from the PC side will be sent after the 800ms delay. INTERNATIONAL CERTIFICATION SERVICES INC. International Certification Services, Inc. [email protected] * Neither PC nor black box side needs to transfer data - PC side is sending POLL control messages every 800ms. Black box will not reply to these messages. The situation where our system will transmit the most messages is case 2 where black box needs to transfer data to the PC side. Our system will transmit POLL control message (20ms - sent by PC side), immediately followed by data message (190ms – send by black box), immediately followed by ACK control message (20ms – sent by PC side). This means the system will transmit for 240ms, followed by 800ms delay.

Bagdons James Mason Australia P/L 25 March, 2003 J.M.A. Computer & Wireless Auto Measuring System The testing was performed at International Certification Services, Inc. at 1100 Falcon Ave, Glencoe, MN 55336 The J.M.A. Computer & Wireless Auto Measuring System was found to be in compliance with the FCC Part 15 Subpart C, Section 15.249 requirements. None INTERNATIONAL CERTIFICATION SERVICES, INC. Applicable Standards 47 CFR Ch.1 (10-1-98 Edition) FCC Part 15Radio Frequency Devices Subpart CIntentional Radiators Section 15.249Operation within the bands 902-928 Mhz, 2400- 2483.5 Mhz, 5725-5875 Mhz and 24.0-24.25 Ghz 2.1Referenced Standards ANSI C63.4-1992Methods of Measurement of Radio-Noise Emissions from Low- Voltage Electrical and Electronic Equipment in the Range of 9 Khz to 40 Ghz. 2.2 Equipment Units Tested The equipment tested is a measuring device to compare vehicle manufacturers data against damaged or repaired vehicles and product a hard copy report of variations at the data reference points of the vehicle. There are three radio transmitters (all identical) in the system. One is for Rod 1 (for reporting the Underbody Measurements), the second is on Rod 2 (for reporting the comparative and Upperbody Measurements), and the third is the transmitter box that connects to the computer for communicating with the above 2 devices. All transmitters operate on the same frequency 916.596 Mhz and are controlled by the device attached to the computer. All receivers are SAW based type devices and do not have a local oscillator. These devices have been verified here at the lab also for radiated emissions and found to be compliant with the 15.109 regulation for Radiated Emission Limits. 2.3 Equipment and Cable Configuration See photos of the EUT PC board and schematic and test configuration setup in Attachment A 2.4 List of Test Equipment Measurement cable losses, and antenna correction factors are included in the Corrected Data column of the data sheet. Quasi Peak Detection was used for measuring the Fundamental frequency signal and Average detection method was used to measure the Harmonics since they were all above 1000 Mhz.

All measurements were taken in dBuV/m with the antenna located at 3 meters distance from the EUT. Frequency measurements are recorded in Mhz. Input power to the intentional radiator was not recorded---only the radiated emissions with the internal transmitting antenna were recorded. 2.6 Location of Test Site The open area test site (OATS) and conducted measurement facility used to collect the data was International Certification Services, Inc. at 1100 Falcon Ave. in Glencoe, MN 55336. This site has been certified to be in compliance with the normalized site attenuation section of CISPR 16-1. (See FCC Registration number: 91103 and Industry Canada File number: IC 3701.) 2.7 Measurement Procedures The antenna was placed at a distance of 3 meters from the EUT. The EUT was set on an insulating table in the OATS site and rotated through 360 degrees to determine the worst case EUT orientation. The antenna was then positioned vertical and horizontal to determine which antenna polarity orientation was worst case. Then certification data was recorded at all the transmitter frequencies from the fundamental to the 10 th harmonic at an antenna height variation of from 1-4 meters. 2.8Reporting Measurement Data See data sheets and plots in Attachment B for the Transmit…
