Messages from Scanner Command Keys
The Gryphon™ I series scanners with display have 3 command keys that can each be associated
with a character to send to the host.
By pressing the keys on the scanner, the associated character with
its relative message formatting
is sent to the Host. For example, keys can be used to select items from a menu sent to the
scanner display by the application program.
The messages are handled by the system as if they wer
e barcodes, that's why KeyID can have so
many fields appended to it. If in your application there is some chance of reading a 1-char
barcode identical to KeyID, the way you can distinguish between the two is to enable the Code
ID: The KeyID is the only 1-character long EAN 8 code.
The default characters associated
with each key (KeyID) are shown in the following table:
(left) Key '<'
(center) Key '='
(right) Key '>'
