I.7 SIMRAD 992 Sonar
This sonar interfaces to Isis as a normal analog sonar having four sonar channels and one
trigger. It connects to the SIU just like any other conventional analog sonar.
Use the hardcopy connector as the output from the 992 to Isis. Do not use the analog
hardcopy connector.
The
hardcopy connector is a 25-way, D-type connector. The connections are shown in
Table I-5.

With respect to its operation in Isis, the Simrad 992 sonar is quite similar to the Klein 595
(described next). In fact, when configuring Isis for the Simrad 992, you can choose the
Klein 595 button in the Select Sonar dialog box in Isis; Isis treats them the same.
