The interface with the PC is done through USB Type B for data exchange and Mini Type B for parameter setting. The RFMU radio is high power 5W UHF radio covers the 430 to 471MHz RF band. The RFM200U is power from 12.5V power supply that is backed up with Lid Accid 12V battery. Connectors P.N.: Book 116 Rev: New Approved: Amir 28/12/10 Data Connector USB Type B used as data link between the RFM200U and the PC. Antenna Tx/Rx and Tx BNC connector. It is used as Tx/Rx (2 ways) antenna connection or just Tx antenna connection if the second Rx connecter is in used i.e. by special jumper in the board. Antenna Rx BNC connector. It is used for Rx antenna connection in case the other connecter is just for Tx. Sets by special jumper in the board. Power Connector. Data LED Updating Parameter Value Changes Confirming Parameter Value Changes Activating Self Test Whenever there is data on the USB cable then the LED is flickering. PTT LED CM LED Whenever the radio is on transmission this LED is on. Whenever the RFM200U senses any RF signal above -107dBm then this LED is on. Data LED Whenever the RFM200U is powered then the LED is on. Preparing for Operation The BSRU100N is not a standalone unit, this device always combined in to products like the RMR perform the following steps:
a. Connecting Assembly Cables Technical Specification General Band Frequency Range Channel Spacing Programming 1. Connect one end of the coax cable to Rx/Tx BNC. In case the Tx and the Rx signals are separated then connect the second (Rx) cable to the Rx Coax. 2. Connect the DC plug to the Power Plug Socket. 4. Connect one end of the data cable to USB rear panel connector. FCC rules and reg. under Operating Voltage Diagnostics b.
