•For special function keys, use <ESC> and <Function Key> to enter their scan code in this mode. For example, to program <F9> into the key position, hit <ESC> first, followed by <F9>. To program <ESC>, hit <ESC> twice.
•Since the following 4 keys are used by Windows, we cannot use <ESC> + <Function Key> to program these keys: <F6>, <F10>, <Alt>, <PrintScreen>. These keys have to be programmed in ASCII mode by entering the key token names.
•The scan codes for multiple keys entered into one key will act as if all the keys were pressed consecutively without releasing the previous one. At the same time these keys will be released when the key at the programmable keyboard is released. Thus, to program
•If a certain key has to act as if it is released within the programming string before the actual key is released, “release codes” have to be inserted manually:
o For regular keys (including Shift, RightShift, and Ctrl), insert <ESC> & <f> followed by the key to be “released”. For example, to simulate press and release of the <b> key, enter <b>, <ESC>, <f>, <b>.
When <ESC> & <f> is entered, the display will show [0F0]. To release <Ctrl> key, enter <ESC>, <f>, <ESC>, <Ctrl>.
o There are some keys that need special code combinations. For example, to release the <RightCtrl> key,use <ESC>,<e>,<ESC>,<f>,<ESC>,<Ctrl>. It will be shown as “[0E0][0F0][Ctrl]”.
o For releasing <Alt> and <RightAlt>, type in [0F0][Alt] or [0E0][0F0][RightAlt] directly in ASCII mode.
ASCII Code Mode
•In ASCII mode, pressing a regular key will enter that key in the definition and be shown as a string of characters. Special function keys will be ignored or used to control entry of data (e.g. Backspace will erase previous character).
•There are some special codes used in ASCII code mode:
o [Caps] Emulates function of CapsLock key. Used in RS232 mode to emulate Caps Lock function for QWERTY keyboards. To insert [Caps]
function, click on the 
icon on the toolbar.
o[CR] Carriage Return code. Used in RS232 mode to emulate <Enter> function.
o[[ Enters the character ‘[‘ character. o ]] Enters the character ‘]’ character.
o [Separator] Separator Code used in
icon to insert a Level Separator Code.
