enter the “hot key programming” mode when the programmable keyboard is already
fully loaded (no more free memory for further programming) by the key contents
previously programmed.
INPUT THE CONTENT TO BE PROGRAMMED
Once the programmable keyboard enters the “hot key programming” mode
with the key to be programmed identified, what the user types on the standard PC or
PS-2 keyboard will be taken for the content to be programmed into that key of the
programmable keyboard till the user exits the “hot key programming” mode.
The legal input in this mode includes all alphabetical letters (including both
upper and lower cases), numerical digits (applicable only for keys at the area above
the alphabetical keys and excluding those on the numerical keypad), symbols (such as
`!”#$ and excluding those arithmetic signs in the numerical keypad) and the “enter”
key. The “shift” key, the “caps lock” key and the “back space” key are also accepted in
this mode to serve an editing purpose (for example, pressing “back space” will erase
the last character of the input instead of being treated as a character for input).
Pressing the “esc” key in this mode will abort the “hot key programming” mode
immediately. All the rest keys (such as the “Ctrl”, “Alt”, “Home”, any function key or
arrow key or any key in the numerical keypad) on the standard PC or PS-2 keyboard
are illegal inputs in this mode. The maximum number of key presses acceptable to any
key by “hot key programming” is 32.
All the input from the standard PC or PS-2 keyboard in this mode will also be
sent to the host computer.
EXIT “HOT KEY PROGRAMMING” MODE
After the intended content of the key is completely entered, the user shall press
the “hot key” again to notify the end of “hot key programming”. The programmable
keyboard will give one beep to signify the normal exit of the “hot key programming”
mode. Should there be any illegal entry in the content of the key or any other improper
operation during the programming, the programmable keyboard will give three beeps
to signify the failure of “hot key programming” and the key content is not changed. If
the user pressed the “esc” key to abort “hot key programming”, the programmable
keyboard will also give three beeps immediately as a response to signify the abort.
