Installation & Hook-Up

Connecting the REC to the 1394

Connect the REC to a 1394 GMC System using the encoder cable
(catalog number 1394-GR04) for each axis. This is a four foot cable
that connects Axis 0 Encoder or Axis 1 Encoder connector on the
REC to the J3, J4, J5, or J10 encoder feedback connector on the 1394.

Important: This cable is polarity sensitive.

Important: The REC does not require power from the 1394 to

operate nor does it provide power to the 1394. However,
the 1394 requires a separate 5V power supply to run its
interface circuitry.

The 1394 interface circuitry requires 0.325A to operate. Any
additional devices connected to the 1394, such as incremental
encoders, can require an additional 0.2A per device (check your
device for the precise requirements).

To connect the encoder cables:

1. Insert the 12-pin plug labeled “REC/AEC” in the Axis 0 Encoder

or Axis 1 Encoder connector on the REC.

2. Insert the 12-pin plug labeled “1394” in the J3, J4, J5, or J10

encoder feedback connector on the 1394.

3. Wire the remaining auxiliary power labeled “ENC. PWR” to the

5V DC power supply. The red wire is +5V and the black is a +5
common.

Important: When using multiple Encoder devices, we recommend

you wire all of the auxiliary power cables to the same 5V
DC power supply.

ATTENTION: The REC does not support the removal
or the insertion of any connectors when under power.
The power disturbance can result in unintended
machine motion, loss of process control, or an electrical
arc that can cause an explosion in a hazardous
environment.
