o Baud Rate – The baud rate is the speed that data is sent from the GPS receiver
to the serial port of the DVL. Set this in accordance with the GPS manufacturer
specifications. If you purchase a GPS from Sensors & Software, this is already
pre-set.
o Saved Strings – the GPS outputs data (called "strings") which is received by the
DVL and saved along with the GPR data. The default setting for this is the GGA
Only string which contains all the relevant positional data. For advanced users
who want access to additional GPS information for post-processing with third-
party software, they can set this to All.
o Serial Port Power - the serial port on the back of the DVL can also output
power, thereby enabling a single cable to be used for the GPS (power and data).
If you use a 3
serial port.
Important: Since the serial port of the DVL outputs power (current=1A, voltage=12V),
be very careful if connecting other GPS units to the serial port. Verify the pins on the
drawing below.
Pressing the Serial Port Power button will turn power to the serial port on, but it will
display a warning message first (Figure 5-41). Upon restarting, the serial port power will
remain at whatever setting the user chose before restarting.
