The RTR970B-PRO is radio data receiver with data logging used with Nokeval MTR series radio transmitters. Device can receive, unpack and buffer data packets into its memory from transmitters. It identifies automatically type of a transmitter, so it can be used simultaneously with different transmitters and with different transmit periods.
The RTR970-PRO uses license free frequency range of 433.92 MHz, so it can be used freely in areas where this so called ISM-frequency range is allowed, covering almost whole of Europe. Receiver can be installed on 35 mm DIN-rail or used as a tabletop device. It can also be installed for example on ceiling or cable rail. Receiver can be connected to computer using USB, RS-485 or RS-232 buses. The PRO receiver can be either used with PromoLog software or accessed from any software supporting Modbus RTU or Nokeval SCL. Nokeval SCL or Modbus RTU protocols are used for data transfer. When RS-485 is used there can be several RTR970B-PRO devices on the bus and they can be positioned to cover larger receive area. Receiver has four diagnostics leds and it needs operating voltage between 8..30 VDC or used with USB.
