to connect to a network switch before connecting to the user interface computer, a standard Ethernet patch
cable may be used. It is not recommended that the Power Module share a network switch with other high-
bandwidth network devices. See section on Network Connections for more information.

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 internally (bulkhead mount version) and used for testing the unit
while in dry-dock.
2. FAULT - Indicates that a transmit signal triggering error occurred. Triggering errors are generally
introduced by electrical interference along the cable. Such errors are generally handled by the Power
Module and do not indicate a problem. This LED is used for troubleshooting purposes.
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.
1.4. Network Connections
FarSounder's sonar systems operate on a standard Ethernet network using TCP/IP protocol layers. Due to
the high bandwidth needs of the FarSounder systems, the network must be capable of 1 Gbps connectivity.
