3.3.3 Battery Setting

(1) Battery Charge Enable/Disable (JP2)

If the AR-B7041 uses a 3.6V Ni-Cd rechargeable battery for SRAM data retention, the on-board charge circuit can be enabled by set the JP2 jumper. The battery will be charged when the power is on.

(2) Battery Output Connector (J4)

The J4 is used to connect the battery to the AR-B7017 when the AR-B7017 is going to be removed from the AR- B7041. A two wired cable provided with the AR-B7017 is used to do this job. This would be very convenient if you are using the SRAM on the AR-B7017 and you want to remove the AR-B7017 temporarily.

(3) External Battery Connector (J3 & J5)

J3 and J5 allow users to connect an external 3.6 to 6 VDC battery to the AR-B7041 if the on-board battery is empty. Only the SRAM disk will sink the battery current. If no SRAM chips are used, no battery is needed. The battery charger on AR-B7041 does not source charge current to the external battery which connected to J3 or J5.
