
Connecting the RS-485 terminal
Two wire communication RS-485 is ready to use for sending data to host computer.

The applicable electric wire is of 0.14 mm
2
to 2.5 mm
2
(AWG26 to AWG14).

For the communication output cable, use a twisted shielded pair.

Up to 32 connections can be made including one for the host computer. For the address
settings, refer to “ RS-485 address setting ” (page 47).

The communication cable length is 500 m at maximum.

To terminate the cable, strip 11 mm of the coating from the tip of the cable and connect it
to the terminal.

Connect a terminating resistor (Rt: 120

) to the terminal device of the RS-485
communication line.
