OPERATIONS MANUAL WRDR RADAR HEAD 108432-000 2 WRDR RADAR HEAD THIS UNIT IS FULLY ASSEMBLED AND READY TO USE. NO CONFIGURATION IS NORMALLY NECESSARY Thank you for choosing the Wanco Radar Head. Your radar is in a Polycarbonate enclosure suitable for outdoor use and is protected against access of oil, dust and water. The radar has been tested to and complies with FCC part 15 class A. The radar head uses a state of the art modern radar transceiver that incorporates a transistor instead of a diode that offers many advantages including reliability. SAFETY Do not look directly into the radar head when it is powered up. Keep any body part away from the radar beam as much as possible. 3 FCC/CANADIAN INFORMATION FCC ID: UQXWRDR432 MODEL: WRDR IC: 6809A-WRDR432 This device complies with Part 15 of the FCC Rules and with RSS-210/Gen of Industry Canada. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modifications not expressively approved by the party responsible for compliance could void the user’s authority to operate the equipment. The term “IC:” before the radio certification number only signifies that Industry Canada technical specifications were met. NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.

There are two ¼ inch mounting bolts to facilitate mounting to a bracket or some other suitable structure. Both mounting bolts should be used since this will make the unit impossible to rotate. The unit should be secure as possible so that it cannot vibrate. The unit is pointed with the lid of the unit away from traffic. The unit must be pointed straight down the road. If the unit is at more than a ten degree angle to the traffic it will start measuring a lesser speed than the actual speed. See the following figure. Towards Traffic The unit has a configurable dip switch. In most cases it will not be necessary to change it, but in rare instances it could be necessary. Remove the lid of the unit to expose the underlying circuit board that contains the dip switch. See the following figure. KPHMPH RUNDIAG 232485 ENADIS 6 Select MPH to display the speed in MPH or KPH to display the speed in KPH. Select RUN for normal operation and select DIAG to output a continuously updated incrementing speed pattern. This is used to test the connectivity and the functionality from the radar head all the way to the display. Make sure to switch it back to RUN after the test is complete. Select 232 to use the RS232 interface, which is the normal setting. Select 485 to select the RS485 interface. Make sure the appropriate cable is in use for the corresponding selection. Select ENA to enable the transceiver, which is the normal selection. Select DIS to disable the transceiver. The radar enclosure has a 6 foot cable attached to it to provide power and communications. Connect the flying black lead to ground and the flying red lead to +12V. Connect the male DB9 to a controller board, modem, computer etc. to provide communication. Since the radar acts like a DCE, to connect it to a PC only a gender bender is necessary not a null modem. The output string is 8 bits no parity 1 stop bit (8n1) 1200 baud in Hexadecimal (Hex) not ASCII. Specifically the data is (2)(84)(1)(SPEED)(1)(AA)(3). This string is output every .5 seconds. The RS232 port can be connected to a computer or some suitable controller for display of the measured speed or for some other purpose such as speed logging. There is nothing that is configurable through the communications port. The pinout of the cable on the DB9 is Pin # Name Direction 2 Receive Data Transmitted from Radar 3 Transmit Data Received to Radar 5 Signal Ground Common OPERATION The radar outputs a continuous wave (CW) at 24.125 GHz. Part of the signal that is transmitted from the radar transceiver is reflected back from objects such as moving vehicles. Due to the Doppler effect, the signal received from a moving object is slightly lower or higher in frequency than what was transmitted. This frequency offset is measured to determine the speed of the vehicle. Only the speeds of vehicles that approach the radar head are measured. Vehicles traveling away from the head are ignored. The vehicle with the strongest signal, which is normally the closets to the radar head is displayed. The radar head is capable of measuring vehicles as far as 700 feet away and in most cases will measure vehicles up to 1000 feet away. The lowest speed the unit can measure is 5 mph and the highest speed the unit can measure is 138 mph. 7 Specifications Power Consumption 130 mA @ 12V NOTES Voltage Range 6V to 30V Temperature Range -40 to +85 qC Untested (Storage and Operational) Type Detects incoming traffic only Interface RS232 DB9 male Tx, Rx…

November 14, 2006 RE: Wanco, Inc. FCC ID: UQXWRDR432 The following is in response to the comments made on the above referenced application. 1) FYI....Please note the frequency listed on the 731 is MHz, not GHz. Our apologies, typo has been corrected. 2) Please provide further internal photographs of the innoSenT module. Photographs of the innoSenT module have been provided. AC powerline emissions do not appear to be provided. Please explain. If the device is intended to operate from any source that can be traced back to AC (i.e. AC to DC adapter), then this should be tested. Additionally, given the terminals are simply wires, it is uncertain how this device can be controlled to battery power only by any user of the device. Note: Section 15.207(c) REQUIRES AC line conducted test data to be submitted unless the device is strictly battery-powered. The last sentence of this regulation states that devices that include, or make provisions for, the use of battery chargers which permit operating while charging, AC adapters or battery eliminators or that connect to the AC power lines indirectly, obtaining their power through another device which is connected to the AC power lines, shall be tested to demonstrate compliance with the conducted limits. The device in question is used at temporary, battery powered installations for detecting traffic speed along roadways. They are powered by 12 VDC lead-acid batteries (or occasionally a generator), and do not employ AC mains power. In addition, they are not used while the trailer/box they are installed in is towed/moved to alternate locations. 3) Part of the test report mentions 15.249. Please explain. Typographical error. The test report has been corrected. 4) Given the nature of this design, it is uncertain how this device can assure compliance with 15.245 (b)(1)(iii). Please explain. As mentioned above, the device in question is not used in a motor vehicle or aircraft. 5) The frequencies given on the 731 form appear to cover 100 MHz, but only one frequency appears to be tested. Normally FCC requires low/mid/high channels. Note Block Diagram and Operational Description support 24.125 GHz, but data suggests 24.113 – 24.115 GHz. Please explain. The device being tested is a CW Doppler radar employing only a single channel of operation. The 731 Form has been updated to reflect only the exact frequency measured on this particular device. However, it is our opinion that the grant should give some leniency within the operating band for variations in the operating frequency of the RF module, as it utilizes a PHEMT oscillator and manufacturing processes will result in minor deviations from the specification. The manufacturer will ensure that all RF modules used remain within the permitted band of operation. 6) For IC it is uncertain if the RX emissions are covered by the results obtained. Results appear to be only for 50 dB down or for Class A emissions. Please note that all spurious emissions measured above 1 GHz are below 54 dBuV/m, and all emissions below 1 GHz meet Class B emissions limits. Ref. Table 6.2. This demonstrates compliance for IC receiver requirements.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 November 27, 2006 RE: Wanco, Inc. FCC ID: UQXWRDR432 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Your response regarding the AC line conducted measurements and installation environments are understood. However the device is not designed such that it is only connected to a battery and there is no assurance that a device approved such as this will only be utilized in the configuration stated unless appropriately approved under a LMA (limited modular approval). If this device is only approved for use in Wanco devices, then a Limited Modular approval limiting the use of the device to within Wanco integrated installations can be considered but would require an appropriate cover letter covering the LMA issues.

THEORY OF OPERATION The radar transceiver uses an advanced PHEMT oscillator to generate a continuous wave (CW) signal centered at 24.125 GHz, which is transmitted via a planar antenna. A very small portion of the signal is reflected off of an object, such as a vehicle, back to the transceiver. Due to the Doppler effect, the frequency of the reflected signal is slightly offset and proportional to the speed of the object. When this reflected signal is mixed with the signal that is transmitted a difference signal in the audio range results. The mixer uses an in phase, quadrature phase approach so that the direction of the object can be eventually be determined by a Digital Signal Processor. The eventual determined directions are object moving towards the radar head or object moving away from radar head. This signal is gained and filtered appropriately and then converted to a digital signal for digital signal processing to determine the direction and speed. A digital string is output to a RS232 port suitable for some sort of external controller or computer to convert for a display or some other purpose. See the block diagram on the following page.

6.7 Potential Health Hazard EM Radiation Level The minimum separation distance calculated following FCC OET Bulletin 65 is calculated as follows, where S is power density, EIRP(dBm) = E 3 (dBμV/m) – 95.2 dB( mW/(μV/m) ) EIRP = 112.8 (dBμV/m) - 95.2 dB( mW/(μV/m) ) = 17.6 dBm ERP = EIRP – 2.15 = 17.6 – 2.15 = 15.5 dBm = 35.1 mW = 0.0351 W Thus, the power density at 20 cm becomes S(mW/cm 2 ) = EIRP(mW)/(4ʌ R(cm) 2 ) = 0.008 mW/cm 2 NOTE: (1) Under no circumstances is the ERP of this device greater than 3W, as required by 2.1091 and the FCC mm-wave accepted test procedures.
