  • Page 10 3.12 Communication Output The device has a two-wire RS-485 communication port with terminals labeled A+, B-. High-speed optocoupler isolation and protection circuits prevent common-mode and differential-mode voltage interference, lightning strikes, and miswiring from damaging the communications port. The RS-485 communication mode allows a maximum of 32 instruments to be connected on one bus. In this case, an RS-232C/RS-485 converter is required. The communication cable can be an ordinary shielded twisted pair cable.
