13.4.1 Common mode noise rejection
Common mode noise on the 48VDC power line to the sonar head should be minimized. The SIM
Controller board has a common mode choke on the power line to the sonar head. If sonar head
power is not supplied by the SIM Controller board, install a common mode choke on the sonar head
48VDC power line. A suitable common mode choke is JW Miller (Bourns) 8102-RC. This is available
from Digi-Key. See the below figure for wiring details.
