Sonar Interface
The Sonar Interface board converts the digital chirp high and low
frequency transmit signals for the 100/400-Khz frequency
systems into corresponding low level analog signals which are
output on J9 to the Power Amplifier boards. In addition, signals
from an optional pressure sensor and an internal temperature
sensor are input on J10, the FSK responder trigger signals are
input on J4, and the digitized received sonar signals from the Side
Scan board are input on J7. Test points and indicators for the
transmit signals and IDE interface logic for the Side Scan board
are also included. +5, +12 and -12 VDC power is input on J5 from
the Power Distribution board.
Side Scan
The Side Scan board is a four channel receiver that provides

analog to digital conversion of the received sonar signals which
are input on J1 from the T/R Switch board. The digitized signals
are output on J2 to the Sonar Interface board. Indicators on the
Side Scan board illuminate when signals are being received.
Sub-Bottom
The Sub-bottom board is a single channel receiver that provides
analog to digital conversion of the received sonar signals which
are input from the hydrophones on J4 on the electronics bottle
connector end cap. The digitized signals are output on J2 to the
Sonar Interface board. Indicators on the Sub-Bottom board
illuminate when signals are being received.
Compass
The Compass board provides heading, pitch and roll outputs to
the USB port of the CPU board.
4-Port USB to Serial
Used to convert USB port signals to serial port signals used to

connect optional serial port peripheral components to the J4
bulkhead connector. Port 0 and Port 1 from the USB to serial
adaptor are connected to the J4 bulkhead connector.
