28 Datalogic™ OPOS Service Object

Device Specific Properties:

DecodeData:

Returns TRUE or FALSE depending on the previous SetProperty call.

ScanData:

Holds the raw scanned data received from the scanner.

ScanData property always has bar code data when a DataEvent is fired. For Tabletop

scanners, the bar code data may be sent across the USB interface as uncompressed

Binary Coded Decimal (BCD), depending upon scanner configuration and bar code

type.

ScanDataLabel:

Holds the scanned and decoded data from the scanner if DecodeData property is

TRUE. If the decoded data did not contain a check digit, the scanner service will add the

check digit to ScanDataLabel for EAN/UPC bar codes.

Contains data if DecodeData is TRUE.

ScanDataType:

Returns scanned data type of the most recent label from the scanner.

Returned value is one of SCAN_SDT_XXXX constants, where XXXX is the type of the

label. Refer to OPOS Scanner header file for the numerical values.

Contains label type if DecodeData is TRUE.

Label type as reported on scanner interface — the scanner assigns a label type identifier

and sends this with the label data across the interface. The Service Object translates this

into one of the OPOS defined label types. For the RS-232 interface, the scanner

configuration must be correctly set for the Service Object to properly identify label type.
