5 Setup the WorkHorse Sentinel ADCP
Figure 6 illustrates how to connect the WorkHorse cables and adapters on
your workbench. The internal battery plugs into a connector on the top
circuit board.
NOTE. When you first receive your WorkHorse, the battery is not installed.
You will need a container of water large enough to submerge the Work-
Horse’s transducer head into during testing (two to three inches of water is
sufficient). Testing the WorkHorse out of water may cause some tests to
fail but causes no harm to the WorkHorse.

5.1 Serial Communication
The standard communications settings are RS-232, 9600-baud, no parity, 8
data bits and 1 stop bit. Self-contained applications receive no benefit from
setting a faster baud rate.
You can set the WorkHorse for baud rates other than 9600 baud. If you
make the new baud rates permanent, WinSC will search for the correct set-
tings, (and will try COM2 but not COM3 or COM4). If you tell WinSC
these settings, you will save time required for searching. If you have trou-
ble connecting to the WorkHorse, use WinSC’s Auto Detect, which searches
for the WorkHorse’s current serial port and baud rate.
RS422
. The WorkHorse Sentinel is normally set for RS232, but it can be
changed to RS422 by changing a switch setting. The switch is in plain view
on the top circuit board, near the cable connectors. Its settings are plainly
