Operating specification
  • Work frequency, from 868 to 870 MHz, which reduces the risk of interferences with the classic radio frequency systems. This work frequency allows also to install new systems in the same environments in which there are weighing systems fitted with the previous interfaces.
  • Up to 50 different channels, easily programmable with the programme on PC, in order to install various independent systems in the same work area.
  • Max. Functioning distance, in appropriate environmental and installation conditions: up to 70m indoors, and up to 150m outdoors.
  • Does not require particular communication protocols, trasmission in transparent manner of any character received in input.
