Introduction

The Worth Data RF Lasers have the following features:

1) The LZ400-RF Laser Scanner

for the USA and Canada. This laser has

a range of 500 feet 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 RF Lasers can communicate with one 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 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 Lasers can also operate

in the same room as the 701 RF Terminal.

4) The R/F Lasers 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 Lasers have a rechargeable lithium ion battery. The battery is

recharged with an included 5v power supply. Recharge time on fully

discharged batteries is 2 hours.
