Output Formats
Data output can be initiated in one of three ways:
1. By pressing the Print button;
2. Using the Print Interval feature;
3. Sending a print command (“P”) from a computer.
RS232 Commands
All communication is accomplished using standard ASCII format. Only
the characters shown in the following table are acknowledged by the
Moisture Analyzer. Invalid command response "ES" error indicates the
Moisture Analyzer has not recognized the command. Commands sent
to the Moisture Analyzer must be terminated with a Line Feed or
carriage return-line line feed (CRLF). Data output by the Moisture
Analyzer is always terminated with a carriage return-line feed (CRLF).
