ACR2000 MOTHERBOARD JUMPERS
Battery Back-Up Select Jumpers (J10 and J11)
These two jumpers allow for disabling and enabling of the battery back-up when a
ACRCOMM communications module is present.
When an ACRCOMM module is present and the jumpers are set to “Battery Function
Enabled”, user programs on the board are retained when power is removed. When an
ACRCOMM module is present and the jumpers are set to “Battery Function Disabled”,
user programs on the board are not retained when power is removed.
When no ACRCOMM module is present, the jumpers must be set to “Battery Function
Disabled” position for ACR2000 to function.
