Step 5: (Optional) Connect the Encoder Signals to the
UMI-7772/7774
If your NI ISM includes an encoder, connect the encoder signals to the UMI-7772/7774.
1.
Connect the DB25M pigtail cable to the UMI-7772/7774 Axis 1 Feedback connector.
2.
Connect the encoder wires to the DB25M cable as indicated in Table 1.
