McQuay OPM to JACE connection

Driver communications is via RS-232 between a JACE serial port and Port A of the McQuay OPM device, using a cable as shown in Figure 1.

The serial cable must be a twisted, shielded pair type with drain wire, maximum length 50 feet. The OPM end must be properly terminated to an AMP or Phoenix plug, with the JACE end typically terminated to a DB-9F (socket) connector for its RS-232 port. Pinouts for the cable are shown in Figure 2.

Figure 2. Pinouts for serial cable using 6-pin AMP connector (top) or 3-pin Phoenix connector (bottom)

Check the OPM to see if it requires the Phoenix plug or the AMP plug (possibly using an AMP-to-Phoenix plug adapter cable).AMP part numbers for the AMP connector shown in Figure 2 are:1-480270-0 (plug) and 60617-1 (female pin terminals).

After you connect this serial cable, the JACE is now ready for McQuay integration, as described in the rest of this document. See the next section McQuay Driver Quick Start for a series of task-based procedures.
