4) GPR data out port mode means that the GPR data stream will be output to the serial
port of the DVL. This is for users who wish to read the GPR data into their own PC or
other device. Contact Sensors & Software Inc. for more details if you want to use this
option.
Note that this option slows down data acquisition speeds.
Baud Rate
The baud rate is the speed that data is sent from the GPS receiver to the serial port of the DVL.
The available options are: 2400, 4800, 9600 (default) or 19200.
Stop Bits
The available settings for Stop Bits are: 1 (default) or 2.
Data Bits
The available settings for Data Bits are: 7 or 8 (default).
Parity
The available settings for Parity are: none (default), odd or even.
End String
The GPS receiver can be set up to send one or more types of data strings to the DVL. These
strings are called NMEA-0183 strings and each contains positional or other information in
specific formats. Each type of string is specified by a 5-character prefix. There are numerous
NMEA strings but examples of three different NMEA strings (GPGGA, GPVTG and GPGSA) are
shown below.

Before using the GPS with the Noggin, the DVL software needs to know the prefix of the LAST
string being sent in each group. In the example above, three strings are being sent each time
(GPGGA, GPVTG and GPGSA). Since GPGSA is the last one being sent in each group, the End
String needs to be specified as GPGSA.
To see what the End String is for your particular GPS, run System Test #1 and note the first 5
characters on the last line after each series of strings is written to the screen. These are the 5
characters that need to be filled in under End String.
