Indicator Lights
There are seven indicator LED's on the front of the Power Module casing. From left to right they are: TX
Off, Fault, Ctrl A, Ctrl B, Ping, Bank 1, Bank 2. (Older versions of the Power Module may not include the
TX Off or Fault indicators.)
1. TX Off - Indicates that the power amplifier is deactivated. This can be set by the slider switch on the
front panel (rack mount version) or internal (bulkhead mount version) and used for testing the unit
while in dry-dock.
2. FAULT - Indicates that the power amplifier is deactivated. This can be set by the slider switch on the
front panel and used for testing the unit while in dry-dock.
3. CTRL A, CTRL B - Indicates internal Power Module logic states. These are used for debugging
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. Once the Transducer Module has
booted, these indicators will blink until the user interface communicates with the Transducer Module.
4. PING - Flashes every time the sonar transmits a ping.
5. BANK 1, BANK 2 - Indicates power amplifier capacitor banks are changed. These indicators may
remain lighted for a short period of time after the unit is powered down.
Installation
The Power Module can be installed in any dry location within 100 feet of the Transducer Module. There
are no user interface components on the Power Module other than a power switch. This means that even
though it has blinking lights, it does not need to be located in a convenient to access location.
Warning
Make sure the Power Module is switched off before connecting to the Transducer Module.
Warning
The Power Module is not water tight and should not be located in an area with condensation.
1.3. Transducer Module Connection Cable
FarSounder's Transducer Module Connection Cable is a custom made cable designed to connect a
FarSounder Transducer Module to a FarSounder Power Module. The wet end connector can be connected
dry or under water. Before connecting the wet end connector, a small amount of silicon o-ring grease should
be put around the black rubber portion of the pins on the Transducer Module's mating connector. Do not
get the grease on the metal conductor pins.
The wet end connector should not be left unconnected while wet or underwater for extended periods of
time. A wet end connector cap is shipped with the cable for use during extended periods of unconnected
wet or underwater use.
This documentation is given as a reference only. This cable is supplied by the Manufacturer and should
not be serviced by the end user.
