Registry

Windows Management Instrumentation (WMI) Compatible

Datalogic OPOS Service Objects provide WMI compatible Remote Manage-

ment for certain scanners when properly configured.

For scanners that sup-

port this data gathering capability, the Serv

ice 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 appli-

cation will then have access to the data. As noted in the r

egistry 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 specifi

cation, 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 scan-

ner/scales under the Windows Management Instrumentation process.

e default WMI repository:

root\CIMV2

contains two class definitions for statistics information:

• UPOS_Scanner

• UPOS_Scale

There will be one instance of each class per unique serial number identified

scanner used by an OPOS object.

OPOS Registry

Datalogic OPOS Service Objects use the Windows registry for configuration

of the OPOS software. When the OPOS package is installed, the installer cre-

ates registry entries under

HKEY_LOCAL_MACHINE\SOFTWARE\OLEfor-

Retail\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.

The registry system on Windows 64 bit machines has changed where

'default' 32 bit application registry settings are stor

ed. In the registry, all

settings will be found under:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432NODE\....]

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

For example, baud rate can be changed in the RS232Scanner registry, 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 communicate to the scanner.
