Interfacing Notes

It is important that the wiring of the cable between the echosounder and the COM port is bi-directional, i.e. allows two-way data transfer, so that the Qinsy driver can send the annotation telegrams, if selected.


Use Settings - Annotation to select the annotation format and output data content.
Use Options - Direct Annotation to send a fix mark and/or annotation comment directly to the echosounder or side-scan sonar.

Use Context Sensitive Help in the Annotation Dialog to get more information about each specific item.


Knudsen 320 echosounder annotation strings may contain annotation field of maximal 68 ASCII characters.
