6 Select
Synchronization Mode
.
• Stand-alone
This synchronization mode is used when the MF90 system is working by itself.
Synchronization is turned off. It is the default setting. The MF90 system operates
using the current settings for ping interval. The operation is 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 MF90 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 MF90 system. The MF90 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
Synchronization Port
to Transceiver Auxiliary
Port .
• Slave
The Slave mode is used if the MF90 system shall transmit only when permitted by
a peripheral system. When the Slave mode is selected, the MF90 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.
7 Select
Synchronization Delay
.
This delay parameter is used differently depending on the chosen synchronization mode.
• Stand-alone
The
Synchronization Delay
setting is not applicable when synchronization is
switched off.
• Master
In Master mode, the MF90 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
.
Note
This delay will only work when the synchronization is set up using a serial port.
