Once you have wired up the DIO card directly or the CIO – 37 interface

and provided external DC power and GND/Common, you can power up

the PC and configure the Media Touch application (ONAIR or Logger) to

the appropriate DIO pins.

Special Notes:

DO NOT attach the CIO – 37 interface and an external 5 volt power

supply while the computer is running as you may damage the card and/or

cable. The state of the device will be unknown and the cable could be

destroyed through shorting and/or overheating.
