6.11 Modbus RTU over RS485

Modbus RTU as implemented in the miniIPS2 and 2e is an industry standard interface protocol that will run
over RS232 or RS485.
The Baud rate is variable 4800 to 19200 with 8N1 or 8E1 framing.
This conforms to the minimum requirements of the MODBUS standard of 9600 and 19200 baud with 8E1
framing.
