28 RC250 Configuration Sub-system #1 Transmitters MoxaD311 ethernet adaptor RP250GD repeater RC250 receiver Serial output to PC and other software Sub-system #2 Sub-system #3 Enables use of standard software packages e.g. LabView/DasyLab and proprietary software

29 RC250 Telemetry receiver Mains powered with built in rechargeable batteries for 24 hours standby operation Provides continuous RS232 output providing identifiers (Tx serial number and channel labels.) sensor readings battery status LCD screen - transmitter serial number displayed Signal strength bar Supplied with configuration software: Set-up transmitter Tx interval Input configuration Scaling (engineering units) Set no data interval

30 RC250 principle of operation Transmitters send a 150mS packet of data at a programmable interval containing identifiers, sensor readings, battery level and checksum The transmitter transmits at a random point in the TX interval The receiver continuously receives and interprets signals from valid transmitters and invalid sources all the time. Only a signal with a valid code and check sum is decoded d d and stored. Only the last reading from a transmitter is stored. Data in the RC250 is transferred to the host PC on demand from the PC application software. Th RC250 l th t d d t f h l if t itt d d t i The RC250 clears the stored data for a channel if no transmitted data is received during the subsequent no data interval which is set in the config program

31 WSR Wireless Sensor Receiver The DC output voltage or current is refreshed and held on receipt of a valid data packet from the transmitter. You can set the transmitter interval with thetreceiver_configtsoftware and set the input type for all standard transmitters except pulse and event types. The transmitters interval range available is 1sec. to 4 hours. Note that transmitter interval can impact on battery endurance. WSR-8V provides 8 x 0-5V outputs WSR-16V provides 16 x 0-5V outputs WSR-8C provides 8 x 4-24mA outputs WSR-16C provides16 x 4-20mA outputs
