Simrad EK15
•
Stand-alone
This synchronization mode is used if the EK15 is working by itself, and no
synchronization is required. This is the default setting. The EK15 will operate
using its internal ping interval parameters, independent of signals arriving at the
synchronization port.
•
Master
This mode is used if the EK15 shall act as a Master in a synchronized system.
The peripheral hydroacoustic system will then only be permitted to transmit
when enabled by the EK15. When this mode is chosen, the EK15 will run using
its internal ping interval parameters, and transmit external trigger signals to the
peripheral system(s) on the synchronization port.
•
Slave
This mode is used if the EK15 shall transmit only when permitted by a peripheral
system. When this mode is chosen, the EK15 will wait for an external trigger to
appear on the chosen synchronization port before each ping.
2
Synchronization delay
This delay parameter is used differently depending on the chosen synchronization
mode.
• Stand-alone: Not used.
• Slave: The EK15 will wait for the delay time after the external trigger signal has
arrived before transmitting the ping. (Post-trigger)
• Master: The EK15 will wait for the delay time after the external trigger signal
has been sent to the slaves before transmitting the ping. (Pre-trigger)
Note that this delay will only work when the synchronization is set up using
a serial port.
3
Synchronization port
This is the interface port currently used to transmit or receive synchronization
signals.
You can select one of the following ports:
• None
• Serial Port 1
