1 VME Dual Port Gigabit Ethernet Board, P/N: 201840-xxx
The Prizm VME Dual Port Gigabit Ethernet Media Converter board provides a fiber optic
link to remote two independent Gigabit Ethernet links over fiber optic cable. This board
was designed to specifically to support a Gigabit Ethernet sonar – the Reson 7125 but the
board can be used in any application requiring Gigabit Ethernet. An industry standard
pluggable small-form-factor (SFP) Gigabit Ethernet (GBE) fiber optic module is employed
to allow easy customization of the fiber optic link characteristics. Single mode fiber is
typically used with this board and optical links can easily exceed 10 kilometers. Multimode
fiber can also be supported but with drastically reduced optical link distance – typically less
than 1 kilometer depending on the fiber specifics.
This board has to be linked with another Gigabit Ethernet board to complete the Ethernet
connection.
NOTE: The Gigabit Ethernet board will only work with Gigabit Ethernet devices.
This board will not support 10 or 100 Mbps Ethernet.
The Gigabit Ethernet board will operate as either a subsea or surface interface board, so it
can be used as a spare for either location. The optical modules used on the board 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 (coarse wave division
multiplexing) 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.
For non-CWDM applications, Prizm can supply the board with SFP’s that contain an
internal bi-direction WDM (wave division multiplexers) for single-fiber operation.

1.3 VME Dual Port Gigabit Ethernet Board Operation:
The Gigabit Ethernet board has three main electrical connectors: two Ethernet RJ-45
connectors and the DIN backplane connector for DC power. The board also has a single 2pin Phoenix DC power connector if the board is used without a VME rack and backplane.
The RJ-45 connectors (J4 and J7) are located at the left side of the board and are standard 8pin Ethernet connectors with an integrated transformers. The RJ-45 connectors each have a
pair of integrated Ethernet status LEDs.
There is single DIN backplane connector (J1) mounted on the tight side of the board for
acquiring +5VDC power. Also a green 2-pin Phoenix connector (J2) is located on the on
the lower right side of the board for supplying the board with DC operating power if the
backplane is not used. Pin 1 (upper pin of the J2 connector and labeled “+5V”) is the
+5VDC input and pin 2 (the bottom pin and labeled “GND”) is the ground.
The SFP optical modules (J3 and J6) are located on the left side of the board.
NOTE: On power-up of the board, both LEDs within RJ-45 connectors J4 and J7 will
briefly flash ON then OFF to indicate that the GBE chips (U5 and J9) are starting.
Even if the two boards are optically connected, neither LED on RJ-45 connectors J4
and J7 will light until a valid GBE signal is present at BOTH ends of the fiber optic
link. Once valid GBE signals are seen at both ends of the link then the LEDs on J4
and J7 will activate.
1.3.1 Gigabit Ethernet Board Indicators and Controls:
LEDS:
There are 3 through-hole right angle LED indicators on the top of the board. There are no
LEDs on the bottom of the board.

briefly when power is applied to the board, otherwise it is not lit.
D7 (Green) Located on the left center of the board, labeled “FIBER TRAFFIC #2”. LED blinks ON
briefly when power is applied to the board, otherwise it is not lit.
D9 (Green) Located on the lower left of the board, labeled ‘TXD #2’, provides an indication that the
Cypress microprocessor has responded to a data request from the PMON2 computer. This
LED is ON for the duration of the transmitted data.

ON for the duration of the received data.
D8 (Green) Located on the lower left of the board, labeled ‘TXD #1’, provides an indication that the
Cypress microprocessor has responded to a data request from the PMON2 computer. This
LED is ON for the duration of the transmitted data.
D10 (Green) Located on the lower left of the board, labeled ‘RXD #1’, provides an indication that the
Cypress microprocessor has received a data request from the PMON2 computer. This LED is
ON for the duration of the received data.

LED Indication
D1 (Green) Located at the upper front edge of the board, labeled “+3.3V”, serves as an indicator that
D4 (Green) Located on the upper front edge of the board, labeled “FIBER #1”, provides an indication that
D6 (Green) Located on the upper front edge of the board, labeled “FIBER #2”, provides an indication that
+3.3V DC is being generated by the on-board DC-DC power supply. Supply voltage 5V
must be present for this LED to be active.
the transceiver module has detected the presence of an input signal on the fiber link. When
‘ON’ indicates that this board has a good level of received optical power from the remote unit

NOTE: THIS LED WILL BE ON WHETHER ETHERNET DATA IS PRESENT OR
NOT.

Data rates supported: Gigabit Ethernet only
1.3.3 Gigabit Ethernet board Dimensions:
Printed circuit board (PCB): 3.937 inches x 6.299 inches
(100mm x 160 mm)
1.3.4 Gigabit Ethernet board Power Requirements:
The Gigabit Ethernet board utilizes approximately 2.5 Watts of power.
• 5.0VDC input, approximately 500mA
1.3.5 Power Section Testing
NOTE: The connectors and components on the bottom of the Gigabit Ethernet board
have pins that are connected to internal supply voltages 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” LED and the “+3.3V” LED is out:
• Check for continuity of PTC fuse F1 with an ohmmeter.
• Replace PTC fuse if open.
If only the “+3.3V” LED is out:
• Verify +5VDC voltage is present at the source
• Replace the board with a spare, nothing repairable.

1.3.6 Optical Section Testing
1.3.7 Ethernet Testing
If the Ethernet link is out or has errors:
• As this board will only work with Gigabit Ethernet traffic, verify that the devices at both
ends of the link are indeed Gigabit Ethernet devices.
• Verify that the Ethernet devices at both ends of the link are powered up.
• Verify that both of the dual LEDS at J4 and J7 are lit to confirm Ethernet activity at the
RJ-45 connector.
• Attempt to PING from one device to the other.
• If the channel is still not operating correctly, first check the field wiring. If the wiring
appears correct, then first replace the subsea Gigabit Ethernet board with a spare and
check the link again. If the problem is still there, replace the surface Gigabit Ethernet
board, with a spare and check the link again.
