If disconnected from your unit’s GPS receiver this button has no effect
on DGPS settings.
Data View Tab
The Data View page allows you
to capture and view the GPS data
being sent to SatViewer by your
unit’s GPS receiver over the COM
port. There are two formats for
data that can be viewed from this
screen depending on if you are
running in NMEA or SiRF Binary
mode, as configured in the GPS
page. This feature is useful if you have a need to view or store the raw
GPS messages as they come out from your unit’s GPS receiver in a textual
format. This feature is for advanced GPS users who need the ability to
store the raw GPS information as ASCII text in one large LOG file. This
feature is intended to collect up to several minutes of data. It is not
intended for extended data collection sessions.
When in NMEA mode, the data displayed is simply the raw NMEA codes
being sent over the COM port, which are displayed in their original ASCII
format.
When in SiRF Binary mode, the data being sent over the COM port is in
binary format and therefore must be converted to ASCII text before it can
be displayed in a useable format. This involves converting each binary
message to hexadecimal text and adding a text tag to each message that
explains what type of message it is.
Chars: Lists the number of characters captured to the buffer. The
maximum amount of characters that can be stored to the buffer is
approximately 64,000 characters. A “% full” indicator for the used
buffer is provided for your convenience.
Capture: Begins capturing the data passing over the COM port and
storing it to a buffer.
Stop: Stops capturing data and outputs the contents of the buffer to the
screen.
Clear: Clears the buffer and any data listed on the screen.
View: Outputs the contents of the buffer to the screen while capturing
data.
