7. Sensor Verification
To verify correct wiring and test the basic sensor operation, blow on the sensor. The
warmth and moisture in your breath should cause the temperature and relative humidity
reading to rise. The output signals can also be checked against calibrated relative humidity,
temperature and pressure devices. Please note that relative humidity can be expected to
vary significantly over short distances and in brief periods of time.
8. Serial Communications
Serial Data Output
The output of the 597A is a fixed length, comma delimited, serial data stream. The serial
output is factory set for 9600 baud, no parity, 8 data bits, with 1 stop bit (N, 8, 1). Please
see appendix E for a list of supported serial commands.
Output Format Detail
The 597A will support only one output format. This format will use fixed length fields but
also include commas to accommodate both standard CSV formatting and legacy
programs that expect fixed length fields.
The parameter order is shown in the table below.
