To use Com 3, connect the communication wires of the supplied RS485 cable to the
MP200 unit’s Com 3 port - see Figure 5.9. Set the port’s baud rate to 9600, address to
1, protocol to Modbus RTU or Modbus ASCII and mode to Slave using the communica-
tion software.
RS485 communication is viable for up to 4000 feet (1219 meters). Be sure to do the
following (see Section 5.1.2 for additional information on RS485 communication):
1. Connect the shield to the shield (S) terminal on the other device’s port. The (S) ter-
minal on the MP200 unit is used to reference its port to the same potential as the
source. Connect the shield to protective earth-ground at one point.
2. Provide termination resistors at each end, connected to the + and - lines. RT is
approximately 120 Ohms.
