This power supply can only be used with AIRcable Serial devices. Order this if you need an external power supply and cannot provide power to the AIRcable Serial modules through pin 9 of the DB9 connector. This is a 110V power supply. See power plug information.
International orders of the AIRcable Serial don't ship with a power supply because of the different voltages and outlet configurations. We recommend using a standard wall transformer with a 1.3mm power plug, supplying a minimum of 5V DC, minimum 100mA or even batteries. Plus is on the inner barrel, minus is on the outer sleeve.
