ACRCOMM MODULE JUMPERS (OPTIONAL)
Battery Enable Jumpers (J5 and J6)
These two jumpers enable or disable the batteries on the ACRCOMM module. A
primary 1000mA-Hr Lithium (LI) coin battery is provided on the module (BT1 – located
on front of board – user-replaceable). A 50mA-Hr rechargeable Vanadium-Lithium (VA-
LI) battery is also provided as a short-term secondary back-up source (BT2 – located on
back of board – factory replaceable only). This allows for continued back-up of the user
memory during replacement of the primary battery.
The factory default jumper settings are set to disconnect the batteries from the
circuit. This prevents the battery power from draining during shipping. The
jumpers must be moved to the Battery Load Enable positions for normal battery
back-up operation.
