USB GPIO (General Purpose Input Output)

Trigger any action on a computer or tablet from a switch or 5 volt input, and/or send a 5 volt signal to any relay or circuit. The X-keys USB GPIO features ten configurable ports, two dedicated 5VDC outputs, and four dedicated short-to-ground inputs. The configurable ports can accept short-to-ground input, 5VDC input, or send 5VDC signal output.

A standard HD15 male connector provides reliable connection to all configurable I/O ports and dedicated outputs. Two 3.5 mm TRS (Tip-Ring-Sleeve, AKA Stereo) ports provide connection to the four dedicated short-to-ground inputs to facilitate the addition of external switches.

X-keys devices can emulate USB keyboard, mouse, game controller, or multimedia commands. These commands can even be stored in X-keys on-board memory and sent without installing special drivers or software on the host device. The X-keys GPIO can also send 5 volt outputs to twelve independent devices. Our free SDKs allow a software developer to integrate our HID input and output messages for direct communication with the X-keys.

Connecting to the HD15 Port

Any HD15 female connector may be used to connect.

3.5 mm Ports

Each of the two 3.5mm ports accepts a 3.5mm plug such as those found on most Assistive Technology switches. A single switch can be plugged directly into each port or the port can accept two switches with a 3.5mm left and right splitter. Please be aware that the splitter must separate the left and right channels to support two switches independently (headphone splitters will not work).
