Keyboard Capture — External USB Device
Allows the unit to capture data strings from an external USB-HID de-
vice.
A keyboard capture consists of a name, a prefix key sequence, and a
suffix key sequence. It is used to capture data strings from a USB-HID
device (for example a USB connected barcode scanner).
For this to work, the USB device needs to be configured to send (1) a spe-
cial key sequence before the data string and (2) a key sequence that ter-
minates the data string. Please note that the prefix sequence should be
chosen with care. All the keys in the keyboard capture’s prefix sequence
will be filtered from regular keyboard input until a mismatch is found.
When a data string is captured by a keyboard capture, the script method
onKeyboardCapture()
is called.
To perform a keyboard capture:
1. Attach a USB-HID device and plug it in.
2. Turn the USB-HID device on.
3. Tap the
Keyboard Capture
button.
