OPTION 3: PROFILER SERIAL DATA OUTPUT WITH PING TIMES
In the standard Profiler system, the "V4" serial output Profiler messages only give information
relating to the Slant Ranges for each of the Pings within the Scan. There are 2 formats of "V4"
data, these being 'Raw' and 'Processed'.
Typically, a profiler scan will have around 100 to 200 Pings generated in each scan (1 Ping
produces 1 Point in the Scanned Profile). For serial transmission, it may be necessary to increase
the Baud Rate to 19,200 Baud when transmitting dual Profiler data with Appended Ping Times out
of the same COM Port.
Important: In order to include the appended 'Ping Time' data in the Profiler output messages, in
'SONV3' the user must select an Application that includes an Attitude Sensor interface…
Click on 'Menu' ->
Choose 'AppSetup' ->
In drop-down list, select Application that includes 'A' (e.g. 'PA' = Profiler + Attitude Sensor).
When a 'PA' Application is running, the Serial Output Profiler messages will include the Appended
message. This will be one of 2 formats depending on whether a Tritech Attitude / Pitch-Roll Sensor
is connected;
1. With
Tritech Attitude / Pitch-Roll Sensor connected - Appended message will be Roll Angle
data for each Ping. N.B.
This message format will be supplied in the Pitch-Roll Sensor manual.
2. Without
Tritech Attitude / Pitch-Roll Sensor connected - Appended message will be Ping Time
data.
1) An example of a 'Raw' Profiler output message for a very short (5-ping) scan is as follows;

010666706667066670666706667<CR><LF>
2) An example of the above with the Appended 'Ping Time' data (delta mode) is as follows;
%D0081022501+00000+00000+00000+00000+000000000303184+0081500015273302000330
