INTRODUCTION:
Have you ever wondered how your TV, VCR, or stereo remote control units
"talk" to the appliance?
The Ramsey LB-56 infrared communications kit will help you to discover how
invisible light can be used to transmit information. You can also explore a
previously undetectable range of frequencies. The communicator is actually two
kits in one, a transmitter to send the information and a receiver to receive and
demodulate this information.
The infrared communicator was designed to be used either separately or as a
transceiver.This can be accomplished quite easily by simply by 'breaking' the
transmitter and receiver PC board into two independent units. As you have
probably noticed by now, the included circuit board has two tell-tale slots near
the center of the circuit board. These slots may separate the two units. Before
we begin building, we'll describe how to separate these units, but you'll need to
decide your usage before you begin assembly.
The companion LB-6 Infrared Light Beam Tianemitter is a complete six-
transistor 30KHz AM transmitter. It has an output range of 30 feet as supplied,
or up to a quarter mile with lenses used on both transmitter and receiver. The
transmitter can accept a variety of input signals from microphone inputs to
music and audio to data. This transmitter "mimics" the way many infrared
remote control units send information.
Throughout the rest of this manual, "infrared" ae be abbreviated as "IR" as
needed.
