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.

switched off.
• Master
In Master mode, the SU90 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.
• Slave
In Slave mode, the SU90 system waits for the delay time after the external
trigger signal has arrived before transmitting the ping. This is often referred to
as a post-trigger.
8 From the list of ports available, select
This is the interface port currently used to transmit or receive synchronization
signals. It must be an RS-232 serial port. Since the synchronization function only
uses the Request To Send (RTS) and Clear To Send (CTS) signals on a serial port,
you may be able to use a port that is already assigned other interface purposes. For
the same reason, you do not need to define any baud rate.
