I'm using a MGE Ups with SNMP card and I can't put it working with OPEN-e

My UPS have ip 10.100.1.32 and OPEN-E is 10.100.1.35.

I went to SETUP -> hardware -> Function: UPS settings. and entered the following information:

Use UPS - Yes
MGE

UPS MODE: Slave
Username : mge username
Password : mge password
MASTER IP: 10.100.1.32
TIMEOUT: 5 Min
SNMP HOST AGENT DOMAIN: 10.100.1.32

Restarted OPEN-E and went to MGE UPS Web administration and sent a test snmp to shutdown the OPEN-E but it dont work.

Also I can't see OPEN-E on the notified applications of MGE UPS.

Can someone help me?
Thanks
