What are the KeyControl 49/KeyControl 49+ power supply specs?
KeyControl 49 / KeyControl 49+ can be used with an optional external power supply. This might be needed in case the USB power from the host computer is not powerful enough. For that, KeyControl 49 / KeyControl 49+ can be used with an optional standard power supply which is not available from us. Definitly a power supply is needed if you want to use the keyboard standalone without a computer.
The power supply needs to be regulated and provide 9V DC with at least 500mA. The outside (sleeve) of the connector is -, while the inside (tip) is +. The connector diameter is 5.5mm (= 2.2in).
