The SHIFT, CTRL, & ALT (Command and Option for MAC) keys must use ON (key pressed) and OFF (key
released) bar codes to properly emulate keyboard functions. For example, to encode a bar code sequence for Ctrl-C,
you would create a bar code of Ctrl ON, C, and Ctrl OFF.
You can also enter any value from ASCII 000 to 255. How you enter the actual ASCII value can vary by
operating system. For example, to enter ASCII 2, encode
Alt On
,
Down Arrow
(number 2 on number pad),
LF
(for the unmarked 5 on number pad),
Insert
(number pad for 0) &
Alt OFF
.
F11
and
F12
are created by encoding
NULLF1
and
NULLF2
as bar codes. Using the table on the previous page,
the coding sequence for F11 would be
%U$A
and F12 would be
%U$B
Special key sequences for USB
If you are using the TriCoder attached to a
USB
port, you can emulate the "
Windows
" key on a PC or the "
Command
" key on a Mac
by encoding ON (key pressed) and OFF (key released) sequences.
%UC
is
ON
,
%UD
is
OFF.
