More Information
Summary:A powered wireless link device powers a bar code scanner or other optical symbol reader and connects it with a remote computer terminal. The link device has a housing that contains a battery, a data-powered RF (or IR) interface unit, a serial data connector on the housing for connecting to a connector on the cord of the scanner, and a wiring assembly to connect data pins of the connector with corresponding pins of the interface unit, and leads that impose a dc voltage on selected pin or pins of the connector and the interface unit. The wiring arrangement may include a voltage regulator IC. The battery may be removable for replacement or recharging. The wireless link device can be belt worn, where the belt has holsters for the device and for the scanner. The link can be effective up to 500 feet or more, facilitating inventory control or similar functions. A link of over a mile is possible. An optional signal splitter or wye adapter permits two devices, such as a scanner and a printer, to be connected at the same time to the RF interface device.
