General Output Message Format
Reporting of status messages for use as an audit trail is one of the two principal uses for the
RS-232 interface. You can effectively disable the asynchronous reporting feature by setting the
interface to quiet mode, see Table 5-9. All messages output from the analyzer (including those
output in response to a command line request) have the format:
X DDD:HH:MM IIII MESSAGE
X is a character indicating the message type, as shown in Table 5-14.
DDD:HH:MM is a time-stamp indicating the day-of-year (DDD) as a number from 1 to 366, the
hour of the day (HH) as a number from 00 to 23, and the minute (MM) as a number from 00 to
59.
IIII is the 4-digit machine ID number.
MESSAGE contains warning messages, test measurements, DAS reports, variable values, etc.
The uniform nature of the output messages makes it easy for a host computer to parse them.
