Teknor Industrial Computers VIPer 821 Technical Reference Manual page 27

The board is installed with a 3.6V, 370mAh lithium battery (22.5x5.6mm, wafer form
factor with plug-in terminations).
SETUPS
Related Jumpers
To enable onboard CMOS backup, connect the battery to the board's circuitry by setting the
W10 jumper to 1-2 position (onboard Battery).
Jumper settings are described in the next Section – Setting Jumpers .
BIOS Level
No BIOS setup is required.
MAKING CONNECTIONS
Initially, the board is shipped with the battery jumper set so as the battery is disconnected
from the board circuitry: W10 in position 2-3 (External Battery).
When operating with the board for the first time, the jumper must be installed in position 1-2.
When setting the board for an external battery the external voltage source must be applied to
the pin 6 of the J11 Power header, and the W10 jumper must be installed in position 2-3.
MORE ...
The internal or external battery can be supervised through the onboard Power Fail Detection
function (battery voltage drops below 3.08V) using the W11 jumper.
For more information on the Power Fail Detection function please refer to the next Section -
Jumper Settings and the Supervisory Feature described in this Section.
