2.4 Scanner module
A laser scanner module is usually integrated in the mobile devices. The laser beam can be activated using a
key located on the left and right of the device.
On the M260SE device, this function is configured by default on the S key so that it can also be used as the
scanner key. On the M260SE device with an alphabetic keyboard, the large scanner key in the middle of the
keyboard is used to activate the scanner. In principle, any key can be re-mapped to a scanner key by
changing the keyboard layout (see Chapter 2.3.1).
2.4.1 Scanner types
Depending on the particular application, various types of scanner modules can be integrated into a mobile
device:
Scanner module Description
SE 955
Short Range Scanner
SE 965
Short Range Scanner
SE 1524
Long Range Scanner
SE 4500
2D imager
The first three scanner module types can read various types of 1D barcodes.
The last scanner module type reads 1D and 2D barcodes and can also be used for photographing. The
photos are in JPEG format with a resolution of 752 x 480 pixels with 256 scales of grey.
2.4.2 Types of use for the scanner module
The scanner module integrated in the mobile device can be used in several ways.
Non-customised applications use a scan data loop in function in the keyboard buffer to insert the scan data
next to the cursor position. This is done by the ScanDrv system program that is described in the following
chapter.
Application developers can use the scanner API that offers them more control over the integrated scanner.
The scanner API is provided by ACD.
As the scanner module cannot be operated on both types at the same time, it is not possible to
simultaneously use both operating modes.
There are also special solutions available to the application developers:
Instead of inserting scan data into the keyboard buffer, the scan data is transferred to the application via a
UDP datagram or via a virtual COM interface.
To do this, it is necessary to perform configuration changes first.
