Scanner SDK for Windows - API - Zebra Technologies

Overview

The Zebra Scanner SDK provides an easy to use yet powerful and extendible set of API commands to interface with scanner devices. The API commands include:

Open
GetScanners
ExecCommand
ExecCommandAsync
Close

Once the SDKs Open and GetScanners commands are invoked and the list of connected scanners is retrieved, all other methods execute through the ExecCommand and ExecCommandAsync commands. This is a user friendly approach, and easy to code in terms of day-to-day programming.

With the evolution of the SDK's capabilities, it is easier to increase the number of methods rather than increase the number of API commands. The benefit to the user is that, once you have the system up and running, a new method is just an additional operation to the existing code.

In addition to the commands above, the Zebra Scanner SDK supports seven types of events:

ImageEvent
VideoEvent
BarcodeEvent
PNPEvent
ScanRMDEvent
CommandResponseEvent
IOEvent

See sample source code for an example of an application illustrating the Zebra Scanner SDK.

NOTE For a list of a scanner's supported attribute (parameter) numbers and definitions, refer to the Product Reference Guide for that model scanner, available from the Zebra Support website at http://www.zebra.com/support. Attributes include configuration parameters, monitored data, and asset tracking information.

Scanner ID

In the SDK context, scanner ID uniquely identifies a scanner device connected to the CoreScanner driver, and is required to communicate programmatically with the device. Developers need to call the GetScanners method of the CoreScanner API in order to retrieve the scanner IDs of connected devices. For example, to switch on a scanner's red LED, the scanner ID of that particular scanner must be obtained to provide that value in the <scannerID> element of inXML of the ExecCommand method call.

During each CoreScanner driver instance, scanner IDs are sequentially assigned to each connected device. When the CoreScanner driver is restarted, the array of connected scanners is reinitialized and previous scanner IDs may no longer be valid. In this case, the GetScanners method must be executed to obtain the new scanner IDs.

During a single CoreScanner driver instance, an RSM (Remote Scanner Management) supported scanner that is unplugged, and reconnected retaina its unique scanner ID. However, a non-RSM device is assigned a different scanner ID each time it is reconnected.

API Commands

Open

Opens an application instance from the user application or user library. This must be the first API command called before invoking any other API command from the user level application.

Syntax


unsigned short Open(
    /* [in] */ IEventListenerXml* pEventListener,
    /* [in] */ unsigned int scannerTypeFlags,
    /* [out]*/ StatusID *status);

Parameters

pEventListener - Input argument of IEventListener class type object reference.

scannerTypeFlags - The types of scanners requested for use with the API. Use "|" to specify multiple types.

    short imageFormat, 
    char* sfimageData,

DEVICE_SWITCH_HOST_MODE (Value 6200)

Description

Switch the USB host mode of a scanner. This reboots the scanner. If the scanner is in HID Keyboard mode, the only supported host variants are IBM Hand-held, IBM Table-top, and SNAPI. To configure this as a silent switch (suppressing reboot beeps) and persist the targeted host mode as permanent, set the parameters in the inXML string.

For a Bluetooth scanner, send this command to the scanner's associated cradle.
