In units supplied with the RC1 (RS485) or RC2 (RS232) options, the Omron E5CK
temperature controller is equipped with RS-232 / RS-485 Serial Communication
capability for use with a customer-supplied host computer. If this option is used, all
temperature and related parameters can be monitored or altered from the host
computer. On these units, the communications wiring is made through a DB-9
receptacle located on the side or bottom of the cabinet. An independent serial cable
should be installed between the host computer and the DB-9 receptacle (not included
with unit).
