The controllers, including the ViewSmart 400,1600, 6400 and Rig Protector, communicate wirelessly with Modbus equipped devices simply by adding our NRTL certified RS-485 radios options. RS-485 Modbus is converted to Wireless Modbus using our popular FHSS 900 MHz or 2.4 GHz Client/Server networks. It is also possible to interface our RC Systems controllers to our own SenSmart 7000 Monitors or other 3rd party Modbus compatible equipment by simply connecting our RS-485 radio modems to the 3rd party Modbus device.
