Configuring Using an SDK Application

Psion Mobile Devices Developers Guide
Internal scanners
Scanner settings are configured using the Scanners applet in the GUI. Refer to the user manual for the
Psion computer for instructions. Most GUI settings can also be configured by an application using the SDK.
The most recently set value, from either source, applies. The SDK cannot set the Translations values, or the
Ports settings.
External scanners
You cannot configure external decoded scanners using the GUI Scanners applet. External non-decoded
scanners are configured using the GUI applet.
13.5.2 Configuring Using an SDK Application
If there is an internal non-decoded scanner and an external non-decoded scanner, they have the same
scanner configuration, and symbology field, settings.
Internal scanners
All the settings that can be configured through the Windows GUI can be configured through the Mobile
Devices SDK with the exception of the translation features and the ports settings.
Configuration uses APIs in:
• C++: PsionTeklogix::Scanner namespace.
• Java: com.teklogix.scanner package.
• .NET: PsionTeklogix.Barcode namespace.
An exception is thrown if an application attempts to set a parameter that does not apply to the scanner.
External scanners
Most external decoded scanners cannot be configured using the Mobile Devices SDK. Some external
decoded scanners, when attached to a serial port can be configured using strings transmitted through the
serial port. Consult the manual for your scanner to find out if this is supported and to obtain the
configuration strings.
External non-decoded scanners are configured using the Mobile Devices SDK. Configuration uses APIs in:
• C++: PsionTeklogix::Scanner namespace.
• Java: com.teklogix.scanner package.
• .NET: PsionTeklogix.Barcode namespace.
13.5.3 Configuring by Scanning Configuration Bar Codes
Internal scanners
By default internal decoded scanners cannot be configured by the use of configuration bar codes. To enable
this mode of configuration, do one of the following:
• Using the GUI:
1. Select the Scanners applet.
2. Select the Barcodes tab.
3. Expand Advanced Options.
4. Enable Parameter Setting.
• By an application:
- Enable the Scanner Setting Scanner Setting Name parameter—see Section 13.6 Configuring Scan-
ners Through the Mobile Devices SDK on page 100.
Symbol Technologies scanners
For the configuration bar codes for the Symbol Technologies decoded scanners used with Psion computers,
refer to “Chapter 10, Parameter Menus”, in MiniScan MS XX04 Series Integration Guide (Part number
72E-67134-06 Rev. A), published by Symbol Technologies. This manual can be downloaded from the
