SERIAL COMMUNICATION PORT
Connect terminal 15 and 14 of the controller to the positive (+) and negative (-) terminals of the
master device.
Note that, PC as a master device cannot be connected (wired) directly to the instrument as PC is
equipped with RS232C serial port which is not directly compatible with RS485 port on instrument
side. In such cases use RS232/RS485 converter as a bridge.
