    Hello Jon，
    Thanks for writing in.
    It can detect two directions of current. When charging, current reading is with “-“sign.
    If it doesn’t have “-“, that means it is discharging. So you don’t need to change the wiring.
    Best regards.

    Hello Jim Beans，
    Thanks for writing in.
    The electrical level from this item is TTL,to communicate with compueter. Fistly you need to conver TTL to RS232.
    Communication protocol is as followed:
    Baud rate: 9600 Bps
    BB CC ADDR 00 XX XX CRC (commandfor current return )
    BB CC ADDR 01 XX XX CRC (commandfor voltage return )

    BB CC is the frame head (2 bytes)
    ADDR is the module address (1 bytes)
    00 is to read the current command (1 bytes)
    01 is to read the voltage command (1 bytes)
    XX XX is arbitrary value (2 bytes)

    Best regards.
