How they work

These radios work just like a wire – just without the actual wire. One radio connects to the controller (master), and a second radio connects to one or more Modbus devices. The communication is bidirectional

and provides the exact same features and functionality as if there was a wire between the networks. Multiple device-side radios may be used with a single radio on the master side.
