Changing the Controller’s IP Address
If you know the SNAP PAC S-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 in case the IP
address has been written there. 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” on page 40
and
then set the IP address as described in the
PAC Manager User’s Guide.
