Synchronization modes
The purpose of the synchronization modes are to set up the CS90 to operate alone, or as a "master" or "slave" in a synchronized system.
Whenever more than one hydroacoustic system is installed on a vessel, interference may occur. To avoid interference, 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.
The CS90 offers functionality for remote transmit synchronization. It can be set up to operate in either Master or Slave mode.
The following synchronization modes are available:
•  Stand-alone
Synchronization is turned off.This synchronization mode is used if the CS90 is working by itself and with no synchronization required. This is the default setting. The CS90 operates using its internal ping interval parameters, independent of any trigger signals arriving at the synchronization port.
The Synchronization Delay setting is not applicable when synchronization is switched off.
•  Master
Master mode is used if the CS90 is going to act as the controlling unit in a synchronized system. The peripheral hydroacoustic system(s) are only permitted to transmit when enabled by the CS90. When Master mode is selected, the CS90 will run using its internal ping interval parameters and send trigger signals to the peripheral system(s).
•  Slave
Slave mode is used if the CS90 is going to transmit only when permitted by a peripheral system. When Slave mode is selected, the CS90 does not transmit ("ping") unless an external trigger appears on the chosen synchronization port. The peripheral system may be any other hydroacoustic product (for example an echo sounder or sonar), or even a dedicated synchronization system.
