The board switches on at +2.5 to + 15V and switches off at -15V to + 0.8V, so it can

To use this function, turn off the power switch (POWER / SW2).

power supply of the board with D-sub No.6 pin, make sure that the
handshake line of the connected device is not affected.

using the AC adapter.

and make sure that the wiring is correct.
