The KE-USB36 provides an interface from switches and other input devices to the PC USB port. This versatile USB encoder emulates a standard USB Keyboard and Mouse device. Any keystroke emulated with the KE-USB36 may also be modified with a Ctrl, Alt, or Shift function, or any combination of the three modifiers. All inputs on the KE-USB36 are individual inputs, activated by shorting to the provided logic ground. In addition to keystrokes, the KE-USB36 inputs may be programmed to emulate mouse Left, Middle, and Right buttons.

The KE-USB36 features a Trackball input for conversion of this device to mouse movement. (A Spinner may be used instead of a Trackball)

The KE-USB36 is programmed through the USB port of the PC using the programming application included with the unit. Once programmed, the configuration is stored on the KE-USB36 in non-volatile memory.

All power for the KE-USB36 is taken from the PC USB port, so no other voltage supply is required.
