Worth Data RF Laser Introduction

Introduction

The Worth Data RF Laser has the following features:

1) The LZ400-RF Laser Scanner for the USA and Canada. This laser has

a range of up to 500 feet (open area) and has collision detect and retry

logic built within. The LZ400-RF Laser communicates with the B78

Base Station. The Base Station communicates with a host PC through the

USB port or a RS-232 Serial Port. Up to ten LZ-400 RF Lasers can

communicate with one B78 Base Station.

2) If you use the USB interface, data is transmitted as keyboard data. If you

use the serial interface instead, serial data is transmitted to one of the

computer's COM ports.

3) The USA LZ400-RF Laser and Base operate in the 902MHz band. The

laser and base radios operate by "frequency hopping" spread spectrum.

The radios hop from one frequency to another every 400ms. The radio

goes through 25 different frequencies and then repeats the sequence – all

in the 902 MHz band at 15 milliwatts (10 dBm) of power. Different

sequences define the channels. It is possible to have up to ten RF

Lasers/Base Stations in the same area, providing each pair is on separate

channels to avoid interference and general confusion. The RF Laser can

also operate in the same room as the 701 RF Terminal.

4) The R/F Laser can read and discriminate between Code 39, Full ASCII

Code 39, Interleaved 2 of 5, Codabar, Code 128, EAN-13, EAN-8, UPC-

E, UPC-E1, UPC-A, MSI, LabelCode4, LabelCode5, Code 93 and

Plessey.

5) The RF Laser has a rechargeable lithium ion battery. The battery is

recharged with the included F10 5v power supply. Recharge time on

fully discharged batteries is 3 hours. Do NOT use any other power

supply to charge your laser.
