Synchronization Mode
• Stand-alone
This synchronization mode is used when the SN90 system is working by itself.
Synchronization is turned off. It is the default setting. The SN90 system operates
using the current settings for ping interval. The operation is independent of any
trigger signals arriving at the synchronization port.
The

switched off.
• Master
Master mode is used if the SN90 system shall operate as the controlling unit
in a synchronized system. Any peripheral hydroacoustic system(s) are only
permitted to transmit when enabled by the SN90 system. The SN90 system
operates using the current settings for ping interval. It also sends trigger signals
to the peripheral system(s).
This mode is unavailable if you set
Port.
• Slave
The Slave mode is used if the SN90 system shall transmit only when permitted by
a peripheral system. When the Slave mode is selected, the SN90 system will 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.

Synchronization Delay
This delay parameter is used differently depending on the chosen synchronization
mode.
• Stand-alone

Synchronization Delay
switched off.
• Master
In Master mode, the SN90 system waits for the delay time after the external
trigger signal has been sent to the slaves before transmitting the ping. This is
often referred to as a pre-trigger.
