SYSTEM CONFIGURATION
Transmitting
Figure 15 Installation settings - Transmitting
This signal goes active at the instant when the transmit pulse starts. It is not required that
the pulse length of this signal be the same as the transmit pulse itself.
If the signal is available, the trigger display will show a red pulse whenever the echo
sounder transmits. Even if the echo sounder is not controlled by the Synchronizing
Unit, a red pulse will appear whenever the transmitting signal is set by echo sounder.
If an echo sounder fails to transmit three times in a row upon being triggered, the
Synchronizing Unit will assume that the echo sounder is no longer available. The echo
sounder is assumed to be not responding if it has not transmitted within 512 ms of
trigger. In this case it will be put into Standby and the system will not be triggered by
the Synchronizing Unit until the operator disables and re-enables the system in Echo
Sounder Status (see section
Echo Sounder status on page 40).
It is also possible to ignore feedback signals for a given echo sounder by selecting
Calculated or Fixed trigger modes (see section
Trigger Modes on page 44 for more
information).
Trigger output (to echo sounder)
Figure 16 Installation settings - Trigger output
The trigger output is a pulse generated by the Synchronizing Unit to signal the echo
sounder to ping. The pulse width can be specified in 1 ms increments.
