4.2 Event log
The matrix supplies a series of information, via the RS232 channel, for recording the succession of
significant events occurring to the system. This log file is also extremely useful for identifying the cause of
faulty operation due to errors when setting up the matrix.
The log can be sent either to a serial printer or to a Personal Computer, for subsequent processing in the
latter case.
Warning! Serial printers are usually provided with a reception buffer: printing will only commence when the buffer is full.
Before removing the paper from the printer force the printer to print the outstanding buffer, following the instructions
given in the user's manual for the printer. Usually OFFLINE forcing followed by page feed is sufficient to empty the
buffer.
Each event has a corresponding message in code that is sent to the RS232 channel. The message is
preceded by an indication of the date and time and is followed by a checksum character.
Typical format of an event message would be
[2003/11/14 18:25:10 PeriodOpen S]
where the
date (in year/month/day format) is followed by the time, by the message and by the checksum. Calculation
of the checksum is described in section 4.3.1.3 Calculating the checksum, page 28.
