Wiring 1394 GMC and GMC Turbo Systems 4-11
The following cables are available to connect auxiliary encoder
feedback to the 1394 GMC and GMC Turbo:
• 1394-GE15 (from the auxiliary incremental encoder to the 1394)
• 1394-GR04 (from the 4100-REC and -AEC to the 1394)
Refer to Appendix D for connectors and accessory part numbers.
Refer to the table below for interconnection information.
Refer to Appendix B for 1326-CEU-xxx Encoder Feedback Cable
information.
Serial Communications
The 1394 provides two optically-isolated RS-232/RS-422 serial ports
(CHAN A/J3 and CHAN B/J4). These ports are located on the bottom
of the system module. Refer to Figure 4.7 for 1394-SJTxx-C and -T
(Series A and B) systems and Figure 4.8 for 1394C-SJTxx-C, -L, and
-T (Series C) systems. Both ports use 9-pin, AT compatible, DB-9
connectors and are identically wired.
You can configure CHAN A/port J3 for RS-232(C) or RS-422, and
you can configure CHAN B/port J4 independently for RS-232, RS-
422, or DH-485. In addition, if you select RS-422 or DH-485, you
can configure the port to use a termination resistor (if required). If
you select DH-485, port J4 is disconnected. You configure both ports
using switches on the system module. Refer to Figure 4.10 for switch
settings and Figure 4.6 for location. Both ports are configured for RS-
232 operation when they are shipped from the factory.
