3.2.2 Output Jobs – Requesting Information from the 1303

Interface output jobs request specific data from the 1303. The output

jobs allow checks of the 1303’s functions and set-up parameters. Out-

put jobs consist of a job header followed by a question-mark; more

specific information is requested by including a data field. An example

of an output-job is:

SAMPLING_PUMP_PRESSURE?<LF>

To which the 1303 responds with the required data. The general syntax

for data output from the 1303 is shown in Fig.3.2.
