Modbus Receiver PCE-SM7
 Modbus receiver for bi-directional communication / 10 channels / 433 MHz / 868 MHz grouping of several devices / RS485 and RS232 interface 

The Modbus Receiver PCE-SM7 allows a bi-directional communication between master and slave-devices. The modbus receiver is able to administer several devices in a group, even if the same transfer channel is used for all. The modbus receiver sends and receives on license-free frequencies between 433 MHz or rather 868 MHz. On those two frequencies the modbus receiver can access 10 channels. The modbus receiver has implemented two ports: RS232 and RS485. Here you can transfer any data streams, not only modbus protocols, per radio. Various data rates allow connecting different devices with different characteristics to the modbus receiver PCE-SM7. The modbus receiver can be configured per computer. The transferred radio data are either encrypted per Manchester-code or per NRZ code by the modbus receiver PCE-SM7. On one channel there can communicate several modbus receivers with a whole range of devices by addressing  through the modbus receiver PCE-SM7. The modbus receiver PCE-SM7 is implemented in fields of energy technology, automation technology and anywhere where a data transfer per wire is not practical.
