To comply with FCC RF Exposure requirements, the antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures with a separation distance of at least 2 meters from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Installation of BA0031 NTR: Installation of Model BA0031 and associated antennae (internal and external) must be performed by trained professionals only. The following antennae (or equivalent) should be used for the various BA0031 models. BA0031-I: Antenna Model – Internal Patch (Sensus Drawing Number 7300574), (4dBi) BA0031-E: Amphenol Antel BCD-8243 (5.15dBi Omni) BA0031-R: Amphenol Antel BCD-87066 (8.15dBi Omni) BA0031 User Manual (12.14.04) Page 4 12/14/2004 General This document describes the installation of the Network Base Station (NBS) / Network Repeater (NTR). The device has 3 different models: • BA0031-I – Two-way device with internal antenna. Works as NBS or NTR. • BA0031-E – Two-way device with connector for external antenna. Works with Antel’s BCD-8243, 3dBd omni antenna (ONLY). Works as NBS or NTR. • BA0031-R – Receive only device with connector for external antenna. Antenna type is not restricted. Works as ‘receive only’ NBS. Does not support NTR mode. Installation Installation Steps 1. Install the supplied ‘LabVIEW’ Run-Time engine and the configuration program ‘Base II v1.12’ in your PC by following the procedure described in Software Package Installation. 2. Disassemble the device top cover. 3. Insert the Ethernet backbone communication cable (not supplied, used in Base Station mode only) and the output cord of the 115VAC to 9VAC transformer (supplied) via the cable entries and connect them. 4. Plug the transformer to 115VAC source. 5. Use the serial communication cable (supplied) to connect available COM port on your PC to the device Console Port (RJ45 connector). 6. Configure the device by following the procedure described in Device Configuration 7. Disconnect the serial communication cable and assemble the top cover. 8. Mount the device and connect to external antenna if applicable. Software Package Installation 1. Insert the supplied CD-ROM. Open the folder ‘LabVIEW Run-Time’ and double click on ‘lvrteinstall.exe’. Next, follow the instructions of the installation program. 2. Create new folder on your PC and copy the file ‘Base II v1.12.exe’ from the supplied CD-ROM to the new folder. 3. Double click the file to run the program ‘Base II v1.12’. BA0031 User Manual (12.14.04) Page 5 12/14/2004 Device Configuration Device Mode Setting 1. Run the ‘Base II v1.12’ program. 2. Select ‘General’ tab. 3. Set to proper PC COMM port. BA0031 User Manual (12.14.04) Page 6 12/14/2004 4. Press ‘Read All’. Verify the device model (BA0031-I, E or R) and version. 5. Set ‘Device Mode’ to ‘NTR’ (BA0031-I & BA0031-E models) or ‘NBS’ (all models). Set ‘Debug Mode’ to ‘Disable’. BA0031 User Manual (12.14.04) Page 7 12/14/2004 Device Mode – NTR (BA0031-I & BA0031-E models) 1. Set the ‘NTR ID’ – The device uses this ID when transmits diagnostics and report messages. The ID range is 1 to 16,777,215. 2. Set the ‘NTR Mode’. In ‘ReTx All’ mode the device retransmits every message it receives. In ‘SL’ mode the device retransmits received messages that were initiated by subscribers listed in the Subscriber List (SL). When working in ‘SL’ mode the device either retransmits the received messages as it receives them (‘Single Hop’ mode) or replaces the ‘Type’ of the received message with ‘ReTx Type’ taken from the stored Subscriber List (‘Chain’ mode). 3. Set the ‘Diagnostic Period’ and ‘Reporting Rate’. Once every ‘Diagnostic Period’, in minutes, the device is generating diagnostics message summarizing the reception and transmission activity in last ‘Diagnostic Period’ minutes. After the transmission of the diagnostics message the device transmits number of Subscriber List report messages according with the number set in the ‘Reporting Rate’ field. In every report message the device reports the contents of two lines from the Subscriber List. And so, if, for example, the Subscriber List contains 100 lines (100 subscribers) it takes 50 report messages to send the whole list. BA0031 User Manual (12.14.04) Page 8 12/14/2004 Device Mode – NBS (all models) 1. Set ‘BS ID’ and ‘BS Tx ID’. The device uses the ‘BS ID’ for identification when sending or receiving messages in t…

The external antenna is connected via a standard N connector. This product is professionally installed. During the installation planning and the installation itself, always done by qualified engineers and technicians, the type of external antennas are carefully selected so that the gain of the antenna is within the FCC regulations, meaning less than 6dBi. 15.204 Antenna description The transceiver uses either an internal antenna or an external antenna: Antenna descriptionGain Internal patch antenna OR4 dBi External monopole antenna3 dBd (5.2 dBi) TEST PROCEDURES All tests were performed in accordance with the applicable procedures called out in the following documents, unless otherwise noted: 1) ANSI C63.4 – 2003, American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz 2) FCC Public Notice 97-114, Guidance on Measurements for Direct Sequence Spread Spectrum Systems FCC ID: KCHBA0031 Sensus BA0031 Spread Spectrum Transceiver 3 of 47 900MHz DTS TEST RESULTS Radiated Emissions, Transmitter Section Test Requirement: 15.205, 15.247 Out of Band Measurements Test Requirement: 15.247 Measurement Equipment Used: Agilent 4440A Spectrum Analyzer, 9 kHz-26.5 GHz Chase Biconolog antenna EMCO 3115 Horn antenna, 1-18 GHZ Miteq pre-amplifier, 1 – 26.5 GHz IFI High pass filter, fp = 1800 MHz Radiated emissions generated by the transmitter portion of the EUT were measured. 1. The EUT was placed on a wooden table resting on a turntable on the test site. Two water meters were connected to the appropriate ports as typical loads. The search antenna was placed 3m from the EUT. The EUT antenna was mounted vertically as per normal installation. 2. The turntable was slowly rotated to locate the direction of maximum emission at each emission falling in the restricted bands of 15.205. 3. Radiated emissions were investigated for a LOW channel, a MID channel, and HIGH channel. Emissions were investigated to the 10 th harmonic. 4. Once maximum direction was determined, the search antenna was raised and lowered in both vertical and horizontal polarizations. The maximum readings so obtained are recorded in the data listed below. Test Results: Worst case results are presented. Refer to data sheets below. Restricted band emissions meet 54 dBuV/m. Other undesired emissions from the transmitter meet the -20 dBc requirement in 15.247(c)FCC Radiated Emissions Limits FCC ID: KCHBA0031 Sensus BA0031 Spread Spectrum Transceiver 4 of 47 900MHz DTS Section 15.205 Restricted bands of operation.
