Synchronization using the Auxiliary socket on the transceiver
The
Auxiliary
socket on the Wideband Transceiver (WBT) offers a "trigger input" signal
for transmit synchronisation from an external system. This synchronization method may be
more stable that the traditional CTS/RTS connection to a serial port.
Normally, the ES80 transmits as soon as it is ready for the next "ping". When transmit
synchronization on the
Auxiliary
socket is enabled, the transmission is delayed until
a trigger pulse is detected on the input. The input trigger pulse must be a low-to-high
transition. "Low" level must be less that 0.7 V, while "High" must be above 2.8 V. "High"
level must not exceed 15 V! Once the trigger pulse is detected, the ES80 will initiate
transmission on all transceivers and frequencies.
The synchronization output on the
Auxiliary
socket offers a "high" pulse (5 V, 100Ω)
that stays "high" during the entire "ping" cyclus. The pulse is always there no matter
which synchronization settings you make in the user interface. The output can be used to
synchronize other hydrographic systems with the ES80 as "master".
The socket fits a Conxall 7-pin Mini-Con-X ®
shielded plug. The connections are made on
pins
2
,
3
and
5
. The plug can be ordered from
the manufacturer or purchased from Kongsberg
Maritime. Use part number 387563.

The parameters on the
Synchronization
page allow you to choose which communication port
to use for the physical connection to the external system, and which synchronization mode
to use. The
Synchronization
page is located in the
Installation
dialog box on the
Setup
menu.
Note
If you use more than one Wideband Transceiver (WBT) in your ES80 system, all
synchronization input signals to the
Auxiliary
ports must be provided by the same source.
Individual synchronization of a single Wideband Transceiver (WBT) is not supported.
If you use more than one computer in your ES80 system, the synchronization inputs to the
Auxiliary
ports can not be used. This functionality is not supported.
