2.4 SERIAL MESSAGES FOR PERSONALISATION AND SETTING
WARNINGBefore sending any message insure that the computer writes with capital letters (CAPS). All commands consist in 4 letters and 3 numbers LLLLXXX.
After having sent a message, wait for an acoustic confirmation signal (BEEP) before sending new strings. If the signal does not arrive it means that the operation has had a negative result, so the last message must be repeated.
VERY IMPORTANT
The usage of these messages is recommended to specialized personnel only.
Don’t forget to send the command MEEE000 to store the variations on the UPS memory.

2.5 HYSTORY OF ALARMS
It is possible to download the alarm history on the computer by typing the following command:
READ XXX XXX = 000 last 100 events XXX = 001 previous 100 events XXX = 002 previous 100 events ...
XXX = 008 first 100 events
During the download the TX CHECK counter on the computer starts to count from 0 to 1800.
To read the history on the computer the F1 key can be pressed.
