MAINTAINING THE SNAP PAC R-SERIES CONTROLLER
Backup Battery
The SNAP PAC R-series controller has a rechargeable battery that receives charging current whenever the
controller has power. It will retain data for up to three years with the power off.
NOTE: Models manufactured before July 1, 2007 have a user-replaceable 3-volt CR2032 Lithium battery (typical
service life with power off: 5 years).
Changing the Controller’s IP Address
If you know the SNAP PAC R-series controller’s IP address, see the PAC Manager User’s Guide for
instructions to change it.
If you do not know the IP address, first check the label on the side of the controller. There are multiple
labels, one for each Ethernet interface; the primary interface is labeled Ethernet 1 . If you still don’t know the
controller’s IP address, reset the controller to factory default settings following the instructions in “Resetting
the Controller,” below, and then set the IP address as described in the PAC Manager User’s Guide.
