3. RADIO DATA RECEIVER e measure DESCRIPTION RTR970B and FTR970B have only one difference the case The benefits in upgraded B version Antenna is moved to the middle in both models and an USB bus has been added to the FTR model B version of FTR is also about half the size of the original The device is a radio data receiver for Nokeval MTR series wireless transmitters It receives and buffers the data packets which have been sent by MTR transmitters It automatically recognizes the types of the transmitters so different kinds of transmitters can be used simultaneously Transmitters can also have different transmission intervals The device uses license free 433 92 MHz frequency band ISM so it can be freely used for example almost in whole Europe RTR970 is 35 mm DIN rail mountable but desktop use is also possible FTR970 is wall mountable The receiver is connected to a computer using RS 485 USB or RS 232 bus and it requires PromoLog application that reads the information from the device Nokeval SCL protocol is used for data transmission between the receiver and the computer Multiple receivers can be connected in parallel to an RS 485 bus to increase the covered area The receiver has three indicator LEDs and it requires 8 30 VDC or USB covered area 50 200 m NN CONTENTS PE SCRIPTION 2 CONTENT IN TAGLINC ene
