Narrow Band Module Evaluation Kit
10Pages

NBEK Issue 1,30 July 2012 Narrow Band Evaluation Kit (NBEK) can be used to evaluate all Narrow Band Multichannel and Single frequency DIL version modules. Radio modules can be assessed for their suitability in terms of wireless operating range, functionality, reliability and robustness in a multi-user environment with several other modules on different channels. Built in Control44, I1200 modes allow user to evaluate the performance of Radiometrix narrow band modules in a typical Remote Control and data transmission application in an industrial environment. Features ■ RF module range testing ■ Noise and interference identification ■ Antenna type evaluation ■ Analogue and digital data transmission ■ 4 Data channel remote control ■ 1200 baud dumb modem ■ Setup is simple as Plug-and-Play ■ RS232 Serial port interface for frequency/channel configuration ■ RS232 Serial port interface for 1200 baud dumb modem ■ Access to internal diagnostic/Test modes using HyperTerminal ■ Access to each data/control pins for external interface or testing ■ 2 Carrier boards according to modules ordered separately o BiM/SMX series (BiM1, NiM2, BiM2A, BiM3B, SMX1 and SMX2) carrier board o xx2M series (TX1M/RX1M, TX2M/RX2M, TR1M and TR2M) carrier board o LM series (LMT1/LMR1 and LMT2/LMR2) carrier board o TLC2H /RLC2H and HVR2 carrier board o SIL series modules (e.g. HX1, NTX2 / NRX2, TX3H/RX3A etc.) carrier board o USX / UHX carrier boards ■ 1 Pair of Radiometrix multichannel or single frequency TX/RX or transceivers (ordered separately) ■ 1 Narrow Band Evaluation Kit manual ■ 1 Data sheet of Radio module ordered ■ 2 1/4 wavelength monopole antenna with BNC connector for 433MHz operation ■ 2 Helical antennas with BNC connector for 151MHz / 173MHz (optional) Radiometrix Ltd Page 1 Narrow Band Evaluati

Configuring the Narrow Band Multi-channel Evaluation Kit One of the Evaluation Kit should be assigned as transmitter and other as receiver. Jumpers on the main controller board 1. Mode C, D require Transceiver 2. In Mode C, a test packet is transmitted, then the unit switches to Receive mode for 100ms before repeating. 4. In Mode D, the unit idles in Receive mode. When a valid CTR44 burst is received the unit keys up the Transmitter and re-transmits this CTR44 burst back to sender in Mode C. 5. The 'modem' mentioned (Mode E) is a 1200 baud RS232 semi-intelligent unit (Transmit keyed...

The carrier board should always be firmly bolted down to the main controller board mounting studs at all four corners, or the grounding of the carrier board will be compromised. This is especially important when high power transmitters are used with the aerial connected directly onto the BNC. In this case, any mismatch will cause significant ground currents to flow.
