Chapter 9: Peripheral Devices & Accessories
The Port Replicator
9.10.7 The Port Replicator
The port replicator (Model# WA4005) is an optional accessory that allows tethered
devices as well as mounted peripherals (e.g., bar code printers or weigh scales) to be
attached to the vehicle cradle. The replicator can be used with or without the cradle
power option.
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)
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 802.11b 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
