Serial Communications
7.1 Overview
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 is a brief introduction to serial communications with SC Series instru-
ments. 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 System connector on the instrument’s rear panel is used, among other things,
for serial communications. See “System Connector” on page 35 for wiring infor-
mation.
All of the serial communications pins on the 25-pin System connector have 500V
of electrical isolation from all other pins and connectors on the instrument. Addi-
tionally, all serial communications pins are protected against electrostatic dis-
charge (ESD).
