13.4.2 Event History Log
This key sequence prints the entire Event History Log of the UPS at the time the data is
requested. The printout begins with the oldest alarm entry in the queue and ends with the
most recent. Any alarms that occur while the Event History Log is printing are included in
chronological order.
The Event History Log lists up to 500 system events in chronological order with the most
recent event listed last. Figure 13-2 shows a sample Event History Log printout.
In this mode, system events are continually logged through the serial port to the device
connected to the port.
The printed log entries contain a time and date stamp and the alarm text message.
Terminal mode uses this format for printing alarm entries:
MM DD YYYY HH:MM:SS.hh KYWD MESSAGE <CR> <LF>
Where:
Equals:
MM Month (2 digits)
YYYY Year (4 digits)
DD Day (2 digits)
HH Hour (2 digits)
MM Minute (2 digits)
SS Second (2 digits)
hh Hundredths of Second (2 digits)
KYWD Keyword (ALARM, NOTICE, COMMAND, or STATUS)
MESSAGE System Diagnostic Information
<CR> Carriage Return Character (ASCII 13)
<LF> Line Feed (ASCII 10)
An alarm message is prefixed by the word “CLEAR” whenever an alarm is entered into the
Event History Log with a cleared status.
If a port is operating in Terminal mode and is connected to a computer, you can press
[Esc] [H] to print the e ntire log with a firmware version header.
