3. MS Connector Only:
If necessary, fabricate the J2 cable. Be sure to use the recommended cable for the required length. The
color code refers to cables supplied with the system. Solder the connections to the MS connector
supplied with the AOM. Use any cable capable of maintaining the signals for the required length.
Ensure the solder connections are clean and free of excessive solder. Use heat-shrink over the solder
connections to prevent the pins from shorting.
NOTE:
The connections to TB3 represent wiring for a typical system configuration (i.e., ±15 Vdc power supply and strain-relief connectors). If the
AOM is configured with other options (i.e., 24 Vdc power supply, velocity output, MS connectors) refer to sections 10.3 and 10.4 for proper wiring.

*Verify if the cable has striped or solid color leads and make connections accordingly.
NOTES:
1. Connect to TB2 Pin A if the stoke length exceeds 180 inches.
4. Strain Relief Only: Connect the cable to the TB2 terminals on the AOM and to the transducer.
5. MS Connector Only: Connect the cable to the J2 connector on the AOM, and to the transducer.
6. Apply power and check the displacement readings at the system electronics.
