The following is a link to Black Box, a manufacturer and supplier of flat (ribbon) type DB9 serial cables that can be used with the TriStar RS-232 connection in place of the standard type of serial cables.  The stand-off height of the connectors on standard serial cables obstructs the re-installation of the TriStar face plate while connected.  The low-profile type of DB9 connectors used on these flat serial cables allows the TriStar face plate to be reinstalled without being obstructed by the RS-232 connection.  This is useful in applications that require a continuous RS-232 connection to the TriStar for remote monitoring/communications purposes.
