4.2.14 Using the Synchronous Cable
6330 Series supports up to 5 sets of mainframe synchronous load control, see 4.2.6 for the
configuration setting. The connection between mainframe is via the RS-232C connector on
the rear panel. Figure 4-6 shows the internal wiring of synchronous cable and MASTER/
SLAVE connection of mainframe. It requires another synchronous cable if one more
SLAVE is desired. Be sure to connect the MASTER port to the EXTENDED port of
previous cable and plug in the SLAVE port to mainframe, and so forth.
