Make sure the equipment is connected to a
power source and turn on the breaker on the
transceiver.
If the NBD-2150 AC/DC Power supply is
connected, turn on its breaker first.
The controller, transceiver and data terminal

and one controller is turned on from
sleep mode, the status display is
displayed immediately without
checking operations.

is as shown at right.
- If errors are detected during the
operation check, the Active
