The Cable Out dialog box allows you to select the specific cable counter to use and
to set up any new cable counters. To use a cable counter that is already on the list,
select it from the
Cable Out Device Type
drop-down list box, and then click
Start
Reading Cable Out
. The cable out value will be displayed in the
Cable out
display
on the tool bar of the Sonar Viewer window when operating in real time.
To set up a new cable counter, click
New Cable Out Device
in the
Device Interface
Definition
area. Here you specify the new device name, which COM port the
computer will use to receive the data, the message format, the location of the cable
out value in the data string, and whether you want the data stored in a log file. A
template is provided for devices that uses a NMEA format message.
SonarPro requires that the cable out value from the device be in meters. You make
this adjustment in the
Cable Out Value Calculation
area by entering a value in the
Scale Factor
text box. For example if the device outputs a value in feet, you would
enter the conversion factor .304800. To zero the value, for example, when the
cable is all the way in and you have a reading of 4 meters, you could enter into the
Offset
text box a correction of -4.
