(2) External Battery Connector (J8)

J8 allows users to connector an external 4.5 to 6 VDC battery to the AR-B1462, if the on-board battery is fully

discharged. Only the SRAM disk will draw the battery current. If no SRAM chips will be used, no battery is needed.

The battery charger on AR-B1462 does not source charge current to the external battery, which connects to J8.

The AR-B1462 didn’t support the audio function. Only by using the AR-B1462A, we just can find this connector.
