RS485-1
The RS485 is used for long distance serial comunication. Distances up to 4000 feet are possible and multiple
devices can be on the network.
120 ohm twisted shielded pair cable should be used for proper line integrity, wired in a daisy-chain fashion.
Star networks should be avoided.
Fail-safe Biasing should be turned on only once. Typically done by the Master device.
Line termination should be turned on at the ends of the network.
Modbus Address is for this Centurion on the Network. The Centurion is a Modbus RTU slave.
Set the communication parameters to match the Modbus RTU Master device.
Reply Delay is only used to slow down the port if the Master requires additional time.
RS232-1
RS232 is used for short distance serial communication. Distances less than 35 feet are ideal in a point-to-point
communication.
Low capacitance, shielded 3 conductor cable should be used, with adequate gage wire to reduce voltage losses.
Devices must share a DC common reference.
Modbus Address is for this Centurion on the Network. The Centurion is a Modbus RTU slave.
