Registry

Windows Management Instrumentation (WMI) Compatible

Datalogic OPOS Service Objects provide WMI-compatible Remote Management for

certain scanners when properly configured. For those scanners that support this data

gathering capability, the Service Objects must be configured via registry settings to

provide scanner data to the WMI data store. There are two registry settings that must be

active to pull data from the scanner and provide it to the WMI data store:

“CheckIHSOnClaim” and “WMIOnClaim” must both be set = 1. When these settings

are active, each time the scanner is “claimed” by an OPOS application, the service will

query the scanner and send the information to the WMI data store. Any WMI-data

gathering application will then have access to the data. As noted in the registry section

below, these settings are defaulted to “active” upon installation. Note that this process

may have a small impact upon system performance.

The data provided to the WMI database follows the format as specified in the UPOS

specification, Appendix I, “Systems Management Information”, which is modeled on

the Common Information Model (CIM) from the DMTF. This standard provides a

means of Remote Management of Datalogic scanner/scales under the Windows

Management Instrumentation process.

OPOS Registry

Datalogic OPOS Service Objects use the Windows registry for configuration of the

OPOS software. When the OPOS package is installed, the installer creates registry

entries under HKEY_LOCAL_MACHINE\SOFTWARE\OLEforRetail\ServiceOPOS;

Scale and Scanner.

Under each UPOS category, there are named entries for each

device. Under each name, there are some user-configurable entries that control the

operation of the OPOS Service Objects.

Scanner

Under SCANNER in the registry, there are a number of named entities: HandScanner,

MagellanSC, QS6000, and so forth. Note that some of these are duplicates that have

been maintained for legacy purposes: for example, “

HandScanner” and

“

USBHHScanner” refer to the same device (a handheld scanner running OEM USB

interface); “MagellanSC” is the same as “SCRS232Scanner”; “TableScanner”

and “

USBScanner” are equivalent; QS6000 and RS232Scanner are equivalent,

QSLScanner is a unique entry. The following screen shots cover the important user-

configurable registry settings for each category of scanner.

Changing items in the registry does not change corresponding items in the

scanner. For example, baud rate can be changed in the RS232Scanner regis-

try, but the baud rate in the scanner must be changed via programming label

to match the registry entry, or the Service Object will be unable to communi-

cate to the scanner.
