Note
Serial line 1 (COM1) is used to communicate with the Operating Panel.
Context
Whenever more than one hydroacoustic system is installed on a vessel, interference may
occur. To avoid this, you have these options:
• The systems are all connected to a common synchronization system.
• One of the acoustic systems is set up as "master", and controls the transmissions on
the other systems.

Selecting synchronization mode
If you wish to use the SC90 as a master or slave in a synchronized system, you must set
it up for such operation. To do this, you must select which communication port to use for
the synchronization interface, and you must select the requested synchronization mode.
Prerequisites
Neither tools nor instruments are required. The SC90 is turned on, and it is working
normally.
• For "slave" operation, a remote system (for example K-Sync ) must be available to
provide trigger pulses.
• For "master" operation, a remote system must be connected. This remote system
must be set up in "slave" mode.
The communication port on the Processor Unit is selected.
