Software Installation

To install the WorkHorse software, do the following.
a. Insert the compact disc into your CD-ROM drive and then follow the
browser instructions on your screen. If the browser does not appear,
complete Steps "b" through "d."
b. Click the Start button, and then click Run.
c. Type <drive>:launch. For example, if your CD-ROM drive is drive D,
type d:launch.

Power

The Mariner deck box automatically scales the input voltage to the proper
level. No special jumpers or switch settings are required to select the input
voltage. If more than one power source is connected to the deck box, the
highest voltage source will be used. Although this is not recommended, it
will not damage the deck box.
. The deck box accepts input voltages of 98-264 VAC, 50-60Hz
AC Power
(J27). This input voltage will be converted to 48 VDC. This is the voltage
supplied to the ADCP.
12 VDC Car Battery
available. The deck box converts the voltage to 48 VDC. This is the volt-
age supplied to the ADCP. Use the largest rated amp-hour battery as possi-
ble. A car battery should last one to two days powering a 1200-kHz ADCP.
DC Power Supply
to the deck box on J25 (20 to 50 VDC, 3.0 A), the voltage from the external
power supply is sent directly to the ADCP. This is useful if you want to in-
crease (higher voltage level) or decrease (lower voltage level) the range of
the ADCP. The current requirement for the power supply is listed as a ref-
erence. Using a lesser-rated power supply can cause the voltage level to
drop. The ADCP will draw only the current it needs.
NOTE. Transmitted power increases or decreases depending on the input
voltage. Higher voltage to the ADCP (within the voltage range of 20 to 50
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.
ADCP Internal Batteries
power (Sentinel Workhorse ADCP or external battery pack) rather then the
deck box power, do the following.
P/N 957-6169-00 (April 2005)
. Use a 12 VDC car battery (J26) when AC power is not
. If you are using an external DC power supply connected
. If you want the ADCP to use internal battery
