MESSAGE FORMATTING

175

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.

automatically set to 00.

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 bar codes, 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 bar code 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 section 5.3 for a compete description of the optional message fields in

square brackets.
