HID Keyboard [BETA]

To use the HID Keyboard, you need a USB A/B cable to connect a PC or Mac computer to the Q-SYS Core 110f processor.

Note: The HID keyboard is designed to control a remote, Q-SYS Core-connected computer from another Q-SYS-connected device (computer, touch screen controller, etc.). The component should not be used directly from the computer connected to the Core, as unexpected behavior can occur.

1. Connect the USB A/B cable's rectangular 'A' connector to a USB port on a PC or Mac computer.
2. Connect the other end of the cable, the square 'B' connector, to the USB B port on the rear panel of the Q-SYS Core 110f processor.
3. On another PC connected to the Q-SYS network, drag the HID Keyboard component into your schematic from the Core 110f inventory tree.
4. Select the component. In Properties > HID Keyboard Properties, select a Keyboard Layout (PC or Mac).
5. Press F5 to save your design to the Core and run it.
6. Double-click the component to open the control panel. Use the keyboard to send keystrokes to the remote computer.

Property	Function	Choices
Keyboard Layout	Select a style for the HID keyboard: PC or Mac. Note: It is possible to control a Core-connected computer while using the opposite keyboard layout. However, some keys are interpreted differently. For example, if you are controlling a Mac computer while using the PC keyboard layout, pressing Print Screen, Scroll Lock, or Pause results in key presses for F13, F14, or F15, respectively.	PC Mac

The HID keyboard contains all the standard keys found on a PC or Mac keyboard. Num Lock, Caps Lock, and Scroll Lock LEDs indicate when these functions are enabled. The Connected LED indicates when the HID keyboard can communicate with the Core-connected computer.

Key Combinations

To send a key combination command, select one or more special keys individually, and then press another key. A special key turns gray when it is active. Press the special key again to deselect it.

PC special keys are Ctrl, Alt, and Shift.

Mac special keys are Control, Option, Command (⌘), and Shift.

Only control pin categories are listed. The properties are the same for the individual pins within each category.

Pin Name	Value	String	Position	Pins Available
Alpha Key	0 1	false true	0 1	Input
Arrow Key	0 1	false true	0 1	Input
Command Key	0 1	false true	0 1	Input
Cursor Key	0 1	false true	0 1	Input
Function Key	0 1	false true	0 1	Input
Keypad	0 1	false true	0 1	Input
LED	0 1	disabled enabled	0 1	Output
Modifier Key	0 1	false true	0 1	Input
Number Key	0 1	false true	0 1	Input
Punct. Key	0 1	false true	0 1	Input

This example shows how you can use a scripting component (in this case, Text Controller) to send the key combination to lock the screen of a Core-connected Windows computer.

Three button controls are used. 'Home' (Windows key) and 'L' output control pins are wired to their corresponding input pins of the HID Keyboard component. A 'Lock_Screen' button control, when pushed, locks the screen of the Core-connected computer.

Lua Script

Controls.Lock_Screen.EventHandler = function( ctl )
  if ctl.Boolean then
    print( "Locking the screen..." )
    Controls.Home.Value = true
    Controls.L.Value = true
  else
    Controls.L.Value = false
    Controls.Home.Value = false
  end
end

Debug Output
