for the Transducer Module to start up, before which time, the SonaSoft™ program will start, but no sonar
information will be visible.
If the TX Off LED is illuminated, no signal will be transmitted. This mode is intended for use in testing the
system while the Transducer Module is not in water, however, it should only be used for limited duration
testing. The slider switch on the front panel of the Power Module controls this feature.
The two Ctrl LEDs indicate internal Power Module logic states. These are used for FarSounder testing
purposes only, and have no user application. The state of these LED's may change from time to time
depending upon the particular mode setting of the sonar system.
After cold booting, the Ctrl A and Ctrl B LEDs will blink alternating AA-BB-AA-BB the hardware is in standby
mode waiting for a SonaSoft™ connection and able to accept firmware updates. The first connection after
a cold boot will take about 1 minute. Subsequent connections will only take a few seconds. After the first
SonaSoft™ connection post cold boot, any time there is no SonaSoft™ connection, the Ctrl LEDs will blink
A-B-A-B indicating the hardware is in standby mode ready to accept SonaSoft™ connections but cannot
accept firmware updates.
