14.2 Configuring Scanners
Scanners are configured using the following methods:
• Through the Windows Control Panel Scanner Properties
• Through application software using the SDK
• By scanning configuration bar codes
All Windows Control Panel settings can also be configured through the SDK. The most recently
set value, from either source, applies. Some scanner parameters, for example those controlling an
imaging scanner in image capture mode, can only be set through the SDK.
When parameters are set through the Control Panel or through the SDK, all accessible parameters
can be set. It is possible to set values for parameters that are not relevant to the scanner connected
to the Psion Teklogix computer. These settings are ignored at runtime.
In some situations, the internal and external scanners share the same configuration settings. All
scanners using the same symbology share the same field settings. For example, if there is an inter-
nal non-decoded scanner and an external non-decoded scanner, they will both use the same
configuration settings.
Only external decoded scanners and RFID scanners are configured by scanning configuration bar
codes, provided by the scanner manufacturer.
14.2.1 Configuring Through The Windows Control Panel
Scanner settings for bar codes are configured through the Windows Control Panel. Psion Teklogix
Windows-based computers have a Teklogix Scanners applet in the Control Panel. Selecting this
icon opens the Scanner Properties window. Refer to the user manual for the Psion Teklogix com-
puter for instructions.
