:

• Automatic Device Replacement (ADR) cannot be used with any

of the drives.

• The RSNetWorx Parameter editor cannot be used.

• Since the RS-485 ports are used for daisy-chaining the drives,

• The AK-U0-RJ45-SC1 Splitter Cable cannot be used to add a

second connection for a peripheral device.

System Wiring

To daisy-chain the drives off the MD65 drive with the
MDCOMM-DNET module (Drive 0), use the AK-U0-RJ45-TB2P
terminal block connector (figure 8.3).

The wiring diagram for using AK-U0-RJ45-TB2P terminal block
connectors is shown in figure 8.4.
