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.
Loading New Firmware
Each SNAP PAC R-series controller contains firmware (sometimes referred to as the
kernel
),
which is similar to an operating system. If the firmware should become damaged, or if a
new version of the firmware is released, you can load new firmware to the controller
following instructions in the
PAC Manager User’s Guide
.
You can also load firmware using a microSD card (on R-series PACs that have a microSD card
slot). See
“Using the MicroSD Card” on page 50
for details.
CAUTION:
Loading new firmware deletes your PAC Control strategy (even if stored to flash
memory) and your persistent variables. Make sure you have
archived
your strategy before
loading new firmware.
Setting Time and Date
The SNAP PAC R-series controller’s built-in clock is set at the factory. To change the time and
date, see the instructions in the
PAC Manager User’s Guide.
