ADDED FEATURE! The KBD03 Now has an auto-repeat option with every pushbutton input. There are also 16 more inputs connecting to ground without matrix wiring (good for ignition switches and other multi-throw switches).

Although primarily intended for Flight Simulator software, the keyboard emulator is perfectly suited for all programs that use keyboard shortcuts (hotkeys). For example CAD, graphics, video editing, office suites and many others. Your own keypads can also be easily incorporated.

Keystrokes are accepted FASTER by the PC than joystick buttons.

The board has a dynamic keystroke output. It ensures that when turning an encoder knob too fast the missing keystrokes will ne sent even after stopping the rotary motion. If this is undesirable, the keys are output in a constant sequence as long as the encoder is turned.

The push-button on the encoder can be used to enable an alternative pair of keystrokes so that the function of the encoder is doubled. This condition is indicated by the LEDs. The push-button input can also be used independently for another switch, expanding the board to 24 switches max.

The board can be expanded by means of a serial bus (I2C). This might be additional switches or digital displays.

All of the settings of the keyboard emulator will be carried out comfortably on a PC program.

An example for using the KBD03 with a flight sim function is with the
REALITY XP GPS software. Reality XP requires keyboard inputs to select and change GPS settings and functions. While using FSUIPC for this purpose, it is a time consuming and a fustrating job. With the KBD03, programming is a snap!
