10.2 J1 Installation Wiring
The J1 cable provides the AOM voltage inputs from the DC power supply. It also provides displacement
outputs to the receiving device.
Take the following steps to connect J1:
1. One of the screws securing the cover of the AOM has a raised head. Connect a ground wire from
that screw head to a central earth ground or to the power supply ground (if it is grounded). Only
one circuit earth ground should be used to prevent ground loops. (Refer to Figure 5-1 of this manual
for a full system grounding diagram.)
2. Strain Relief Only: Fabricate the J1 cable, and prepare the cable as described earlier. Identify the
connections to TB1 and TB3. Refer to section 10.3 to determine the appropriate J1 connections.
3. MS Connector Only: Fabricate the J1 cable. Refer to section 10.4 to determine the appropriate J1
connections. Solder the connections to the MS type connector (Part No. 370017). 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.
4. Identify the wires at the other end of the cable for connections to the power supplies and the
receiving device. Test the cable for shorts.
5. Make sure the power supply is off. Complete the cable connections at the power supply.
6. First, make sure there is no voltage present on the receiving device input connections. Then,
complete the cable connections to the receiving device.
7. Strain Relief Only: Connect the cable to the TB1 and TB3 terminals on the AOM.
8. MS Connector Only: Connect the cable to the J1 connector on the AOM.
NOTE:
Do not route the J1 cable near high
voltage sources.
! CAUTION !
The input to the receiver electronics
should be a passive, resistive device to
prevent damage to the AOM.
NOTE:
Make sure that the power supply can pro-
vide +15 Vdc at 250 mA and -15 Vdc at
65 mA (use a bipolar power supply). The
power supply should provide less than 1%
ripple with 2% regulation. The power
supply should be dedicated to the trans-
ducer system to prevent noise and exter-
nal loads from affecting the system
performance.
