5.5.5 Digital Link Ports
The four 8-pin RJ-45 Digital Link Port connectors (labeled “B1”,
“B2”, “B3”, and “B4” on the front of the Control) provide
communications between Control and Digital MMC Smart Drives.
Also provided on the RJ-45 connector is a green “Link” light
(which will be on if there is a Drive connected to the branch) and a
green “Activity” light (which will be on whenever a data packet is
transmitted to the drive(s) on the branch).
Each of the four branches (two branches on the Digital MMC-D32)
can control up to 16 drives. A “straight-through” shielded cable
must be used when connecting the Control to the Digital Drive.
Connect the cable from the Control to the Drives “IN” connector.
Refer to the MMC Smart Drive manual for Drive information.
