3.4 I/O Cable and AC Power Supply
Systems shipping after August 2002 include the new style I/O cable and the
48 VDC AC Power Adapter in place of the 24 VDC AC adapters. The AC
Power adapter converts AC power into 48 VDC output for the WorkHorse
input power. Increasing the input voltage to the ADCP from 24 VDC (stan-
dard AC adapter) to 48 VDC increases the transmitted power, and thus the
range of the ADCP.
NOTE. Transmitted power increases or decreases depending on the input
voltage. Higher voltage to the ADCP (within the voltage range of 20 to 60
VDC) will increase the transmitted power. The transmitted power is
increased 6 DB if you double the input voltage from 24 VDC to 48 VDC.
For a 300kHz WorkHorse ADCP, each additional DB will result in an
increase in range of one default depth cell.
The higher input voltage is sufficient to override the internal battery voltage
(i.e. the ADCP will draw all power from the AC adapter even if the battery
is installed and connected).
NOTE. This change is not applicable to Rio Grande and Mariner systems.
4 Conventions Used in Manuals
Conventions used in the WorkHorse manuals have been established to help
you learn how to use the WorkHorse quickly and easily.
Windows menu items are printed in bold: File menu, Collect Data. Items
that need to be typed by the user or keys to press will be shown as <F1>. If a
key combination were joined with a plus sign (<ALT+F>), you would press
and hold the first key while you press the second key. Words printed in ital-
ics include program names (BBTalk) and file names (default.txt).
Code or sample files are printed using a fixed font. Here is an example:

6 WorkHorse Care
This section contains a list of items you should be aware of every time you
handle, use, or deploy your WorkHorse. Please refer to this list often.
6.1 General Handling Guidelines
• Never set the transducer on a hard or rough surface. The ure-
thane faces may be damaged.
• Always remove the retaining strap on the end-cap underwater-
connect cable and dummy plug when disconnecting them. Fail-
ure to do so will break the retainer strap.
• Do not apply any upward force on the end-cap connector as the
I/O cable is being disconnected. Stressing the end-cap connec-
tor may cause the ADCP to flood. Read the Maintenance guide
for details on disconnecting the I/O cable.
• Do not expose the transducer faces to prolonged sunlight. The
urethane faces may develop cracks. Cover the transducer faces
on the Workhorse if it will be exposed to sunlight.
• Do not expose the I/O connector to prolonged sunlight. The
plastic may become brittle. Cover the connector on the Work-
horse if it will be exposed to sunlight.
• Do not store the ADCP in temperatures over 75 degrees C. The
urethane faces may be damaged. Check the temperature indi-
cator inside the shipping case. It changes color if the temperature
limit is exceeded.
• Store batteries in a cool dry location (0 to 21 degrees C).
• Do not store batteries inside the ADCP for extended periods.
The batteries may leak.
• Vent the system before opening by loosing the end-cap. If the
ADCP flooded with batteries installed, there may be gas un-
der pressure inside the housing.
• Do not scratch or damage the O-ring surfaces or grooves. If
scratches or damage exists, they may provide a leakage path
and cause the ADCP to flood. Do not risk a deployment with
damaged O-ring surfaces.
• Do not lift or support a WorkHorse by the external I/O cable.
The connector or cable will break.

P/N 957-6151-00 (August 2002) page 9
6.2 Assembly Guidelines
• Read the Maintenance guide for details on WorkHorse re-
assembly. Make sure the housing assembly O-rings stay in their
groove when you re-assemble the WorkHorse. Tighten the hard-
ware as specified. Loose, missing, stripped hardware, or dam-
aged O-rings can cause the WorkHorse transducer to flood.
• Place a light amount of DC-111 lubricant on the end-cap connec-
tor pins (rubber portion only). This will make it easier to con-
nect or remove the I/O cable and dummy plug.
• Do not connect or disconnect the I/O cable with power applied.
An exception to this is the external battery case. The external
battery case connector is always “hot” when batteries are in-
stalled. When you connect the cable with power applied, you
may see a small spark. The connector pins may become pitted
and worn.
• Do not attach a Workhorse Monitor or Sentinel I/O cable or
power supply to the Workhorse Rio Grande ADCP. The Work-
horse Mariner, Monitor and Sentinel ADCPs are 24 VDC sys-
tems. The Workhorse Rio Grande uses 12VDC only.
• The WorkHorse I/O cable is wet mate-able, not under water
mate-able.
6.3 Deployment Guidelines
• Read the appropriate WorkHorse User’s Guide and the Software
User’s Guides. These guides have tutorials to help you learn
how to use the ADCP.
• WorkHorse Sentinel batteries are shipped inside the ADCP but
not connected. Connect the battery and seal the ADCP before
deployment.
• Align the compass whenever the battery pack or recorder module
is replaced, or when any ferrous metals are relocated inside or
around the WorkHorse housing. Ferro-magnetic materials af-
fect the compass.
• The AC power adapter is not designed to withstand water. Use
caution when using on decks in wet conditions.
• Avoid using ferro-magnetic materials in the mounting fixtures or
near the Workhorse. Ferro-magnetic materials affect the com-
pass.
