Long-Range Handheld
Remote Control Transmitter
The Long-Range Handheld transmitter is ideal for general-purpose remote
control and command applications requiring extended transmission distances.
The stylish Long-Range Handheld transmitter features a small external antenna
which allows up to 1,000-foot (300m) transmission ranges line of sight. As
a part of our DS Series OEM family, it is available in 315, 418 (standard), or
433.92MHz. It has been pre-certified for FCC Part 15, Industry Canada, and
European CE (433MHz only) compliance, reducing costs and time to market.
Addressing:
A DIP switch is used to set 10 address lines, giving 1,022 unique
addresses. The address lines should be set the same on the receiver to enable
communication. This helps prevent accidental activation by another system,
but does not provide a high degree of security. This makes it suitable for
applications that benefit from the simplicity of DIP switch addressing and don’t
require a large number of unique addresses.
Protocol:
The DS Series encoder inside the Compact Handheld transmitter
supports two protocols. The first protocol is based on the Holtek HT640
encoder. It is completely backwards compatible with older generation Linx
transmitters and receiver systems based on the HT658 decoder that were
designed to operate with the Linx transmitters. The second is a serial protocol
that offers more noise immunity and faster response time while keeping the
simple DIP switch addressing.
Tactile Buttons:
The membrane switch uses metal snap domes for a sharp
click and tactile response.
Pre-certified:
All units have FCC and Industry Canada certifications, the
433MHz version also has European CE certification.

Accessories:
Optional accessories include retractor reel, lanyard and a rubber

Customization:
The membrane switch can be customized to suite a particular
application. This includes rearranging the buttons, different numbers of buttons
(up to 8) and custom artwork. Logos or artwork can also be applied to the
case. NREs and minimum orders apply.

Typical Receiver Application Circuit
The Long-Range Handheld transmitter is a complete remote control transmitter solution in a very generic package. The
receiver side of remote control applications tends to be much more specific to each product. The receiver should incorporate
the LR Series receiver and DS Series decoder as shown in the schematic below. The LR Series RF receiver outputs the
data received from the transmitter to the decoder. The decoder decodes and verifies the data and, if everything is correct,
replicates the transmitter’s inputs on its outputs. These outputs activate whatever circuits are required by the application.

LR Receiver and DS Decoder Schematic
Basic Evaluation Kit
The Basic Evaluation Kit gives a designer all the tools necessary to incorporate
the Long-Range Handheld transmitter, LR Series receiver, and DS Series
decoder into a product. The Kit serves several important functions. It allows
the performance and features of the transmitter, LR Series and DS Series to
be quickly evaluated. It shows how to design with the receiver and decoder
and how to interface with other components. It also demonstrates the overall
system function, making it easy to develop the initial system design. It allows for
additional circuitry to be placed directly on the board so that it can act as the first
prototype of the product. All of the signals are available on a wire-wrap header for
easy connection to external circuitry.
