Code ID, Code Length and Code can be different content in the reader. These features can be programmed with Reader
Data Header/Terminator on page 121, or Keypad Data Header/Terminator on page 121.
Field code ID and Code length may also be programmed in the reader:
[C Header] [Reader Addr] [Reader Addr delimiter] [Cradle Addr] [Cradle Addr delimiter] [Time Stamp ][Time Stamp
Delimiter]
[ R Header]
[C ID] [C len]
CODE
[R Term]

NOTE:
in case of double formatting for
[Code ID] [Ccode len],
only one of these is included in message formatting.
Specific Data Format
[R ID] [R len]
takes priority over general Data Format.
The code field
[CODE]
as additional formatting in the 16-key model, when the device is programmed in Qty/Code mode.
6.3 Messages from SCANNER Command Keys

PowerScan BT8300 keypad
The PowerScan™ BT8300 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 general format is:
[Header] [Reader_Addr] [Reader_Addr_delimiter] ] [Cradle_Addr] [Cradle_Addr_delimiter] [Time stamp] [Ts_delimiter] [Code ID]
[Code Length] KeyID [Terminator]
[Items in square brackets are optional.]
The messages are handled by the system as if they were 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:
