Serial Communications
7.1 Overview
Serial communications is only available if the instrument was purchased with
Option 53a (RS-232) or 53d (RS-485).
The SC Series instruments are designed to communicate with a remote computer
system or terminal for the purpose of transferring data values from the instrument
to the remote system. The remote computer or terminal also can control many of
the functions performed by the instrument.
This chapter explains the SETUP Menu items relating for serial communications.
A separate instruction manual is available to assist with the hookup and wiring for
data communications as well as provide detailed information of all the available
commands. Ask for manual 008-0610-00, “SC Series Communications Guide” or
download it from http://www.honeywell.com/sensotec.
7.2 Wiring
The Options connector on the instrument’s rear panel is used, among other
things, for serial communications. See “Options Connector” on page 31 for wiring
information.
All of the serial communications pins have 500V of electrical isolation from all
other pins and connectors on the instrument. Additionally, all serial communica-
tions pins are protected against electrostatic discharge (ESD).
