Working Example 2

Application:

Working technique:

Survey on contaminated waste land.

Recording four different levels of different gasses with the

surveyed points.

Using a gas analyser to measure the levels of gasses at various

The gas analyser outputs the results as an ASCII message and

sends the four different levels it has measured to the GPS1200

receiver in the format:

GS1 2.786<CR/LF>

GS2 0.034<CR/LF>

GS3 1.395<CR/LF>

GS4 0.025<CR/LF>

GS1 to GS4 is the message ID for the four different gasses. The

numbers are the gas reading in ppm.

The ASCII Input interface needs to be configured such that when

a position is measured, the ASCII message is split and that each

individual gas reading is recorded as a separate annotation. For

example, annotation 1 would contain the value 2.786,

annotation 2 would contain the value 0.034 etc.The message ID

is used to "search" the input for that particular gas reading.
