The functionality of the WORKABOUT PRO tether port is replicated into RS-232 
serial interfaces by the port replicator. It provides the user with 3 DB9 serial 
interfaces as well as one Type B USB port (for connecting a Host device).

9.11  Bluetooth Peripherals

The WORKABOUT PRO C (a unit equipped with a colour display)

–

comes 

equipped with a Bluetooth radio, making 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 is limited to approximately 5 meters.
Psion Teklogix provides built-in support for the Bluetooth peripherals listed below.

•

GSM/GPRS universal handset

•

Bluetooth printer

Keep in mind that Bluetooth and IEEE 802.11g radios both operate in the 2.4GHz 
band. Although the WORKABOUT PRO 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 hand-held at the same 
time, they cannot transmit simultaneously

–

this has a negative impact on overall 

system throughput. To minimize the impact on the backbone 802.11g network, 
Psion Teklogix recommends using Bluetooth peripherals that have low transaction 
rates (such as printers and scanners).
Refer to “Bluetooth Setup” on page 219 for information about setting up your Blue-
tooth devices for communication. In addition, review the manual shipped with your 
Bluetooth device to determine the method used to associate with the WORK-
ABOUT PRO host.
