The IO-Warrior is an USB Input/Output device by German manufacturer Code Mercenaries.

It is an HID device that does not require any special drivers, and there are multiple versions with a different number of digital I/O pins available. Each pin can be used as either an input pin (to execute remote control commands), or as an output pin (from a script).

Open the standalone config app or the Control Panel, go to the Remote Control page, and add a new IO-Warrior remote.

In the configuration dialog, first select the desired IO-Warrior device from the list. mAirList will open the device and query the number of pins, which may take a few seconds.

For each pin, you can select or type a remote control command for the event that the pin goes on or off, respectively.

Pins can be used as output pins from a script. You can access an IO-Warrior remote through the following function which will return a reference to an IIOWarriorRemote interface:

function IOWarriorRemote(iIndex: integer): IIOWarriorRemote;

Remotes are 0-based, so for example, IOWarriorRemote(0) access the first IO-Warrior remote in the system.

The IIOWarriorRemote interface provides two functions:

function GetPort(iPort: integer): boolean;
procedure SetPort(iPort: integer; iValue: boolean);

GetPort will return the current state of any port. (The first port has index 0.)

SetPort will set the state of a port, using that pin as an output pin. Note that once this function has been called for a pin, that particular pin will be an output pin and cannot be used as an input pin anymore until you power-cycle the IO-Warrior device.
