Attention!
Return Policy for Instruments with Anti-fouling
Treatment
WET Labs cannot accept instruments for servicing or repair that are treated
with anti-fouling compound(s). This includes but is not limited to tri-butyl tin
(TBT), marine anti-fouling paint, ablative coatings, etc.
Please ensure any anti-fouling treatment has been removed prior to returning
instruments to WET Labs for service or repair.

Warranty
This unit is guaranteed against defects in materials and workmanship for one year from the
original date of purchase. Warranty is void if the factory determines the unit was subjected to
abuse or neglect beyond the normal wear and tear of field deployment, or in the event the
pressure housing has been opened by the customer.
To return the instrument, contact WET Labs for a Return Merchandise Authorization (RMA) and
ship in the original container. WET Labs is not responsible for damage to instruments during the
return shipment to the factory. WET Labs will supply all replacement parts and labor and pay for
return via 3rd day air shipping in honoring this warranty.
Shipping Requirements for Warranty and Out-of-warranty Instruments
1. Please retain the original shipping material. We design the shipping container to meet
stringent shipping and insurance requirements, and to keep your meter functional.
2. To avoid additional repackaging charges, use the original box (or WET Labs-approved
container) with its custom-cut packing foam and anti-static bag to return the instrument.
• If using alternative container, use at least 2 in. of foam (NOT bubble wrap or
Styrofoam “peanuts”) to fully surround the instrument.
• Minimum repacking charge for PCCS meters: $60.00.
3. Clearly mark the RMA number on the outside of your shipping container and on all
packing lists.
4. Return instruments using 3rd day air shipping or better: do not ship via ground.

1. Overview
The Power and Communication Conversion System (PCCS) allows the user to supply power
from either a 110 or 220 VAC (50–60 Hz) outlet, and communicate via a USB port. The
PCCS has two components:
• The deck unit, which converts AC power to DC power and has a communication port.
• The submersible unit, which converts the DC power and outputs 12 VDC to the
user’s instrument.
Deck box with USB cable, software, power cord.
Sea cable not shown.
Submersible unit with patch cable
1.2 Deliverables
The PCCS ships with the following components:
• Deck box.
• ac power cord.
• Three foot long A–B USB cable. (A longer cable may be purchased.)
• Optional: Floppy disk with installation software.

3. Instrument Setup and Operation
The Power and Communication Conversion System (PCCS) submersible accepts a power
input voltage of 48 volts (pin 4), from the deck box, and outputs 12 volts of regulated power
from socket 2. Communication with the meter of choice is via the patch cable.
Note
The patch cable is an additional component of the PCCS and its length is customer-specified.
It will typically be 8-pin-to-6-socket.
Setting up and checking the functionality of the PCCS requires the following:
• deck box
• power converter
• patch cable
• host computer with host software installed (WETView or WET Labs Host)
• meter to generate data
• USB cable. Note that its associated software needs to be installed first.
1. Connect the deck box to an AC power source.
2. Connect the 10-pin cable to the SEA CABLE connector on the deck box and the other end
(sockets) to the submersible’s connector.
3. Connect the USB cable to the deck box and host computer.
4. Connect the patch cable to the submersible and the meter that will be generating data.
5. Turn power on at the deck box.
Data should appear in the window of the host software.
3.1 Diagnostics
1. Use the push to test buttons to verify
• 48 V power supply to the sea cable.
• Transmit from the submersible unit
2. The RX and TX light in the top of the deck box should light, indicating the meter is
sending and receiving data via the USB port.
3. When the deck box is receiving AC power, the power switch is backlit red.
4. The sub unit is equipped with an indicator light that lights when the unit is receiving
12V power.
4 The Power and Communication Conversion System (PCCS) Revision D 13 Jan. 2006
• If the backlight on the power switch
fails to light when AC power is
supplied, check the 250V, 2 amp, 5 x
20 mm slow-blow fuse. It may need to
be replaced.
The ability to transmit settings to a data logger such as a DH-4 is accomplished using an
8-conductor cable. When sending settings to a data logger, the TX light will be lit.
