6 MESSAGE FORMATTING

The system always provides scanner to host data communication using the following message formatting:

Output Message from PowerScan® D8330 or PowerScan® M8300 Stand-alone

Towards Host

[Header] [Scanner_Addr] [Scanner_Addr_delimiter] ] [Cradle_Addr] [Cradle_Addr_delimiter] [Time stamp] [Ts_delimiter] [Code ID] [Code Length] CODE [Terminator]

[Items in square brackets are optional.]

Output Message from PowerScan® M8300 STAR-System™ Towards Host

[Time stamp] [Ts_delimiter] [Header] [Code ID] [Code Length] CODE [Terminator]

[Items in square brackets are optional.]

For PowerScan® M8300 models with display, if the RS-232 interface is selected for communication between the Host and the BC-80X0 cradle, then the following additional communications between Host and Scanner can occur:

•The Host can send messages to any scanner associated with that cradle to control the Scanner’s display, LEDs and beeper.

•The Scanner can send up to 3 user-defined characters to the Host using the 3 command keys on the Scanner.

These communications and their relative message formatting are detailed in the following paragraphs.

6.1MESSAGES FROM HOST TO READER

The general format to enable the Scanner for a 2 way communication is:

[Scanner_Addr] [Scanner_Addr_delimiter] MESSAGE [CR]

NOTE:

•If you have enabled the Scanner Address Stamping or the Scanner Address Delimiter, you must specify them in every message.
