”. This will cause an alarm to occur
any time the word “test” is received.

the setup menu and select “Serial Settings” then “Serial Port 1 Settings”.

received on port 1 for alarms in data alarm family 1.

Testing
Connect to the unit via serial connection on I/O 1 and enter the string “test” and then <ENTER>.
This should trigger the above data alarm, and an SNMP trap should be sent to trap manager #1. If
this is not the case, repeat the Network and Data Alarms settings.
Note:
There will be a 30 second delay in alarming if the terminal emulator being used does not send a
LF with the CR. This may be circumvented by pressing <CTRL + J>.
