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 EK80 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 EK80 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
Synchronization Port
.
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 can use a port that is already used for other purposes. For the same reason,
you do not need to define any baud rate.

Synchronizing the EK80 by means of the Auxiliary port
The Wide Band Transceiver (WBT) offers an
Auxiliary
port that can be used for
synchronisation purposes. This synchronization method may be more stable that the
traditional CTS/RTS connection to a serial port.
