7.1 External Bar Code Readers
7.1.1 PowerScan™ Standard, LR and XLR Bar Code Scanners
The 8525/8530 supports Psion Teklogix’ PowerScan™ industrial bar code scanner
with standard, long range and extra long range options.
To connect this scanner to the 8525/8530, attach the device to the tether port. Before
using the bar code reader, you may need to change some parameters. For details,
review “Scanner Properties Setup” beginning on page 128.
7.1.2 Entering Data With The Bar Code Reader
Note: For helpful scanning tips, refer to “Scanning Techniques” on page 44.
When a label is scanned successfully, the 8525/8530 will beep if configured
appropriately and the scan LED will flash. Occasionally, the bar code labels are
poorly printed or damaged and cannot be read properly. In this case, use the
keyboard to enter data from the label.
7.2 Bluetooth Peripherals
If the 8525/8530 is equipped with a Bluetooth radio, it is possible to communicate
with a variety of Bluetooth peripherals, including GSM/GPRS handsets, scanners,
printers, and so on. The range of the Bluetooth radio in the 8525/8530 is limited to
between 2 and 5 meters.
Psion Teklogix provides built-in support for the Bluetooth peripherals listed below.
• GSM/GPRS tri-band universal handset
• Bluetooth printer
Keep in mind that Bluetooth and IEEE 802.11b radios both operate in the 2.4GHz
band. Although the 8525/8530 includes features to minimize interference,
performance of the system will not be optimal if you use both radios simultaneously.
Typically, when both radios operate in the 8525/8530 at the same time, they cannot
transmit simultaneously – this has a negative impact on overall system throughput.
To minimize the impact on the backbone 802.11b network, Psion Teklogix
recommends using Bluetooth peripherals that have low transaction rates (such as
printers and scanners).
