ES70 External triggering

Whenever more than one hydroacoustic system (echo sounder or sonar) is installed on a
vessel, interference may occur. To avoid this, the systems may either be connected to
a common synchronization system, or one of the acoustic systems may be defined as
a Master.
The ES70 echo sounder include interface for remote transmit synchronisation. The
system can be set up to operate in either Master or Slave mode in relation to an external
synchronization or hydroacoustic system.
The ES70 system may comprise more than one General Purpose Transceiver. If the ES70
operates as a Master, the synchronization between these are controlled by the echo
sounder software. If the echo sounder operates as a Slave system, the transceivers must
be individually controlled by the Master system.
Note
In its default configuration, the ES70 is set up to operate as a Master. Special action
must be taken to reconfigure the echo sounder for Slave operation. This is made in the
dialog by selecting
Operation

Synchronisation using a serial line

According to the standard specifications for RS-232, an output must generate a voltage
level of +5 to +15 Vdc (logic "low"), and -5 to -15 Vdc (logic "high") into a load of 3 to
7 kΩ. An RS-232 receiver must present a 3 to 7 kΩ load , converting an input of +3 to
+25 Vdc to logic "low", and an input of +3 to +25 Vdc to logic "high".
The physical wiring between the ES70 computer and the sonar Interface Unit is shown in
section Sonar synchronisation on page 44. Any of the ES70 serial lines can be used, and
it connects to terminal board
