4.7 Changing the ACU IP Address or SNMP Community Setting
Click on the box to the left of the row containing the IP address for the air conditioner. The row will
be highlighted and the IP Address and SNMP Community will be set in the corresponding fields
in the Single Hoffman A.C. Monitor tab. These fields will be used to communicate with the air
conditioner.
Click on the Single ACU Ethernet Info tab. Click on the “Read Ethernet” info button. The current
Ethernet configuration will be displayed. Edit the fields as desired and click “Reprogram ACU”
button. The updated network configuration will re-program the air conditioner.
Note: The IP address and SNMP Community settings cannot be changed from the Multiple
Hoffman A.C. Monitor tab. You can use the Single ACU Ethernet Info tab to change the IP
address or SNMP Community settings.
Note: You will need to modify the configuration in the Multiple Hoffman A.C. Monitor tab to
correspond to the new network configuration for the air conditioner.
