4. CONNECTING THE EXTERNAL
INTERFACE CS-120A
When upgrading from the CSH-20 series sonar, the External Interface CS-120A can be
used. Connect the CS-120A to the processor unit as shown on the next page. However, we
recommend that you connect external devices directly to the processor unit, to avoid signal
delay.
Install the following power supply kit (option) in the processor unit to enable use of the
CS-120A.
