The LED control escape sequences are intended to activate the LEDs for short
periods of time and can be used in combination with the Beeper. The LED and
Beeper will be controlled by the system after the entire command sequence is
interpreted.
Example:
ESC [ 6 q ESC [ 3 q ESC [ 7 q
Turns on the green LED, emits a good read tone, and
turns off the green LED.
ESC [ 6 q ESC [ 5 q ESC [ 7 q
Turns on the green LED for 100 ms and then turns off
the green LED.

6.2 MESSAGES FROM SCANNER COMMAND KEYS
The PowerScan
®
M8300 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] [Scanner_Addr] [Scanner_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.
Refer to par. 5.3 for a compete description of the optional message fields in square
brackets.
