1 Mini4 Dual Sonar Board, P/N: 201630-xxx

The Prizm Mini4 Dual Sonar Board provides two independent fiber optic links to remote the
Reson 8xxx and Simrad EM3002 single/dual beam sonars. The Dual Sonar Board can be
jumper selected to support both single-ended (single coax) Reson sonars and differential
(dual coax) Simrad sonars. This board only provides for the sonar’s uplink (subsea to
surface) data link, the downlink (surface to subsea) control link must be handled through
another separate multiplexer. The control link for the Reson and Simrad sonars may require
specific electrical protocols (i.e. RS-232, RS-485, RS-422 or other) and the sonar
manufacturer’s interface manual should be consulted.

The Dual Sonar Board can be jumper configured to operate as either a subsea or surface
interface board, so can be used as spare for either location. The optical modules used on the
board (pluggable small-form-factor (SFP)) are inherently bi-directional and care must be
taken to ensure the correct optical port (either TX or RX) is connected, depending on the
board configuration and system location. While the optical module’s receiver will operate
on all of the 16 CWDM wavelengths (1270 to 1610nm), the module’s transmitter only emits
at a single wavelength so care must be taken to ensure the correct wavelength is used.

The Dual Sonar Board supports PMON II diagnostics through the RS-485 diagnostics cable.
Diagnostics will display the optical parameters from both of the SFP modules and will also
show the sonar activity (both into and out of the board) on PMON II. Note: to acquire
diagnostics from the remote Dual Sonar Board, the board must be either stacked on top of a
Mini4 Video Input or Output board or have its 3-pin Phoenix diagnostics cable connected to
a Mini4 Video Input or Output board.

1.1 Mini4 Dual Sonar Board Revision History:

The Mini4 Dual Sonar Board has gone through the following printed circuit board (PCB)
and Assembly revisions:

PCB Revision A/Assembly Revision A Original design..

1.2 Mini4 Dual Sonar Board Dash (-) Number Definitions

The Mini4 Dual Sonar Board has a Dash Number appended to the part number. This
Dash Number identifies the specific board configurations:

-001 original configuration.

1.3 Mini4 Dual Sonar Board Operation:

Each independent sonar link has two 50-ohm SMB coaxial connectors. These connectors
will be active as inputs or outputs depending on the jumper settings. For single-ended
(single coax) sonars, only the top SMB connector will be active (labeled IN/OUT A+ or
IN/OUT B+). For differential (dual coax) sonars, both of the connectors will be used.

The sonar fiber links are identified as link “A” or “B”.

There is single green 2-pin Phoenix connector on the on the right side of the board for
supplying the board with +5VDC. Pin 1 is the +5VDC input and pin 2 is the ground.

There is single black 3-pin Phoenix connector on the on the right side of the board for RS­485 diagnostics. Pin 1 is the RT+ signal, pin 2 is the ground/shield and pin 3 is the RT­signal. A Prizm Diagnostics cable can be connected directly to this 3-pin connector or
through a stacked Mini4 Video Input or Output board.

NOTE: To complete the RS-485 diagnostics link from the surface to the subsea boars, the
Dual Sonar Board must be stacked onto a Mini4 Video Input or Output board to complete
the link over the multiplexer’s fiber.

1.3.1 Dual Sonar Board Indicators and Controls:

LEDS:

There are 4 surface mount vertical LED indicators on the top of the board and 4 surface
mount right-angle LED indicators on the bottom of the board.

1.3.2 Mini4 Dual Sonar Board Specifications:

Number of Sonar links: 2 per board
Sonar type supported: Reson 8xxx or Simrad EM3002
Data rates supported: Depends on sonar
Maximum Sonar data rate: 600Mbps

1.3.3 Mini4 Dual Sonar Board Dimensions:

Printed circuit board (PCB): 3.55 in x 3.775 in x 0.60 in board-to-board
(90.1mm x 95.88 mm x 15.24 mm)

1.3.4 Dual Sonar Board Power Requirements:

The Dual Sonar Board utilizes approximately 650mA @ 5VDC.

1.3.5 Power Section Testing

NOTE: The connectors on the bottom of the Dual Sonar Board have pins that are
connected to +5VDC and ground. If these pins are inadvertently shorted together or to a
common chassis ground, the board fuse (F1) will trip/reset.

If both the +5V Power LED +3.3V Power LED are out:

• Check for continuity of PTC fuse F1 with an ohmmeter.

• Replace PTC fuse if open.

If only the +5V Power LED is out:

• Verify +5V DC is present at the source

• At J8 if powered off of external power

• At J3 or J4 if powered off of the stacking connectors.

• If +5V is not available replace the board with a spare.

• If +5V is available check the display LED (D1).

Page 11 of 14

Moog Components Group 201630-xxx Mini4 Dual Sonar Board Manual, Preliminary 2/23/09

If only the +3.3V Power LED is out:

• Verify +5VDC at F1 or J8 (replace board if +5VDC is not available)

• Verify +3.3VDC across C33 on top of board

• If +3.3V is not available replace the board with a spare.

• If +3.3V is available check the display LED (D5).

1.3.6 Optical Section Testing

For surface boards, if the “FIBR A” or “FIBR B” LED is off or flickering, one or more of
the following conditions is likely:

• The fiber is broken or damaged.

• The optical transceiver module is defective at either the surface or subsea board.

• Excessive light loss (low received optical power) is being experienced.

• The Mini4 board (not the optical transceiver module) is malfunctioning.

• There is not enough attenuation in the optical link and the receiver is saturating.

If excessive optical loss is being experienced, the following conditions may be present:

• May have sonar data errors.

• Check the optical level with an optical power meter and inspect all fiber optic

connections including CWDMs and slip rings.

To determine if the fiber is broken, a laser module is out, or the board is malfunctioning,
first:

• Verify that the optical transceiver is tight in its socket.

• Verify that shunts (jumpers) are placed per system jumper configuration.

• Check all fiber optic connections including CWDMs and slip rings to make sure that

they are not causing the problem.

• Check that the optical fiber cable is straight at connectors on board for minimum

optic loss.

1.3.7 Sonar Testing

If one or both sonar data channels (links) are out or has errors:

• Using a signal generator set for about 5MHz squarewave with a amplitude of about

1Vp-p, insert this signal into appropriate connector (J5 or J9) of the channel being
tested. The test signal should be input into subsea (vehicle) Dual Sonar board.

• On the other end of the link, connect an oscilloscope to the corresponding connector (J5

or J9). Verify that there is a 5MHz squarewave being output from the surface Dual
Sonar board and that the signal is not distorted or has glitches (noise) in the signal.

• If the channel is not operating correctly, first check the field wiring. If the wiring

appears correct, then first replace the subsea Dual Sonar board with a spare and check
the sonar link again. If the problem is still there, replace the surface Dual Sonar board,
with a spare and check the link again.

Page 12 of 14

Moog Components Group 201630-xxx Mini4 Dual Sonar Board Manual, Preliminary 2/23/09

• If any of the LEDs are not operating correctly check one of the other channels. If the

LEDs operate on that channel, replace the Mini4 board with a spare board or use the
working channels only.

1.4 Stack Mini4 System Installation Checkout Procedure

NOTE: The Dual Sonar Board will work in a stand-alone configuration without stacking
the boards above a Mini4 Video Input or Output board. Without a Mini4 Video board,
the subsea diagnostics will not work but the board will still carry a sonar signal.

For this PC/104 stack Mini4 System installation checkout procedure, it is assumed that the
Mini4 System is composed of a Video Input board mounted in the vehicle and a Video
Output board on the surface. +5VDC power for the Mini4 boards is supplied by the user’s
DC power supply powering the PC/104 stack and should be verified to be between
+4.75VDC and +5.25VDC at the 2-pin Phoenix power connector.

1.4.1 Diagnostics Overview

The Dual Sonar Board has been designed to include hardware and firmware for monitoring
various parameters of interest. This capability is accessed via a 3-pin Phoenix connector on
the board that carries bi-directional RS-485 telemetry. The diagnostics will typically be
used in conjunction with a user-supplied PC on the surface, which has been loaded with
PRIZM Modem Monitoring S/W (PMON II).

For the Dual Sonar board, the Diagnostics feature requires that there be a functioning
multiplexer system for connectivity between the topside Diagnostic PC and the remote
multiplexer. The Mini4 Video Input and Output board have a transparent link for carrying
the Diagnostics across the fiber link and does not require a user’s RS-485 channel. If the
Dual Sonar board is stacked on a Mini4 Video Input or Output board diagnostics is
automatically connected.

NOTE: The diagnostics feature in no way interferes with normal operation of the
modem – it is not necessary to be running the diagnostics software for any of the
Mini4 boards to work.

1.4.2 Required Communications Hardware for Diagnostics

The diagnostics capability is accessed via the 3-pin Phoenix connector on the Mini4 boards,
which provides the RS-485 connectivity to the on-board processor for diagnostics
communications. RS-485 was used because of its multi-drop capability, which in this case
allows all the Mini4 boards to be communicated with via a single channel. In this
configuration, no RS-485 multiplexer channel is needed.

The user is required to communicate with the Mini4 boards of the system via RS-485. A
typical installation is shown in the following drawing. This details a diagnostic connection
from a Windows PC running PMON II to a Min4 board stack.
