460V 3 PHASE MMC SMART DRIVE NEXTGEN
6.1.3 Digital Link Ports
The two 8-pin RJ-45 Digital Link Port connectors (labeled “IN” and “OUT” on the front
of the Drive) provide communications between the Drive and other Digital Link
devices (another Digital Drive, a Standalone MMC Digital Control, Slice I/O Coupler,
DL-DIU, etc.). There is a green "Link" light located in the upper-right corner of each
connector. If this light is on, another Digital Link device is properly connected to the
associated "IN" or "OUT" port.
A “straight-through” shielded cable must be used when connecting the Drive to other
Digital Link devices. Connect a cable from another Digital Link device’s "OUT" port to
the Drive’s “IN” port, and another cable from the Drive’s “OUT” port to the next Digital
Link device’s "IN" port.
