Chapter 3: Getting To Know Your 7535/7530

Operating RFID/Scanner Modules

Psion Teklogix 7535/7530 Hand-Held Computer User Manual

• Aim at the bar code and press the scan key or the trigger.

• When the scan button or trigger is pressed, a red, oval shaped light (the

framing marker) is displayed. Centre the framing marker in the field –

either in the centre of the bar code you want to scan or in the centre of the

area in which multiple bar codes are to be scanned.

Illumination LEDs will flash and a picture of the bar code(s) is taken.

3.8.7 Operating RFID/Scanner Modules

The RFID module is a short-range device. Configuration is not required for the

RFID reader.

Important: For successful reads, the distance from the hand-held to the

RFID tag varies depending on the type of tag.

Reading An RFID Tag

• Turn the hand-held on. Wait until the unit has booted up completely.

• Position the scanner window of the 7535/7530 no more than 1 centimetre

from the tag. Depending on the type of tag you are reading, you may actu-

ally need the 7535/7530 scanner window to touch the RFID tag.

To test how the unit reads and writes RFID tags, a demonstration application has been

provided. The demo application - RfidReader - is located in the \Windows folder.

This demo application performs the following tasks:

• Loads the internal RFID device driver and displays driver/device information.

• Reads the in-range tag data when the scan trigger is pressed.

• Converts the tag data to text format and outputs the text to the keyboard buffer.

• Provides a UI (User Interface) to notify the operator that the RFID device is

currently active (since there is no physical indicator from the reader).

• Provides a UI to allow the operator to modify various text conversion settings.

Note: The UI (User Interface) for this application is a single system tray icon.

The icon changes when the RFID device is active and also indicates a

successful or unsuccessful scan. In addition, it displays a “scanning” bar

code indicator during the read process.

• Caches a short list of previously read tags to make it easier for the operator

to repeat the ‘output to keyboard buffer’ process.
