Modbus RTU Host Controlled Operation
A simple host-connected system uses an RS485 serial cable to connect the DX80 Gateway device to a host system.
The host system may be a PC or a PLC unit. Because the serial cable is used to connect to a host system, the communications protocol
used is Modbus RTU. The wireless network is a Modbus slave.
In this configuration, the wireless network collects I/O data and sends it back to a Modbus host system.
