The MS Series encoders and decoders are ideal for one-way remote control
applications. They are used to transfer the status of up to eight buttons or contacts
across a wireless or wired link. The large, twenty-four bit address size makes
transmissions highly unique, minimizing the possibility of conflict between multiple
devices. The encoders and decoders are configured through a simple hardware
interface, so no programming or software is required.
Encoder/Decoder Configuration: The MS Series is configured by connecting pins to supply
or ground. There is no software or programming required.
Unique Addressing: The MS Series offers a simple hardware addressing method without
the need for software or programming. A 24-bit address is created in the encoder by
pressing and holding a button. The address is learned by the decoder with another button
press. The 24-bit address provides over 16.7 million addresses, so the chances of adjacent
systems activating each other is very small.
More Buttons: The MS Series supports up to 8 data lines that can be connected to buttons,
contacts or microcontroller lines. This offers more functionality than many similar parts.
Additionally, the outputs can be set as latched or momentary by setting the logic state of a
single pin.
Control Permissions: The MS Series can be configured so that certain encoders can only
activate certain outputs on the decoder. This allows the creation of user groups and
relationships rather than an all-or-nothing activation.
Receiver Power Control: The decoder can power the receiver on a 10% duty cycle.
This allows the receiver to stay asleep 90% of the time, conserving power consumption in
applications where power is critical. Likewise, the encoder can power on the transmitter only
when it is sending data.
Transmitter Identification: The decoder outputs a binary number identifying the encoder
that sent the transmission. This allows access attempts to be logged.
Low Power: The MS Series has extremely low power consumption, making it ideal for
applications with a limited power supply, such as a coin cell battery.
Development System: The MS Series Master Development System allows customers to
easily evaluate the performance and operation of the MS Series. The Development System
features an encoder paired with a Linx LR Series Transmitter on the sending side and a
decoder and paired with a Linx LR Series Receiver on the receive side. The boards are fully
assembled and feature a prototyping area with full access to all of the lines for the encoder
and decoder. This makes it very simple to interface the Development System to prototype
circuits to test operation.

Typical Application Circuits
When activated, the encoder encodes the current states of its inputs and its address into a packet and outputs a digital data
stream. This data can be sent to a decoder by RF modules, infrared link or even a wire. The decoder checks the received
packet to make sure there are no errors and that the received address has been learned. If everything is good, then the
decoder replicates the encoder’s input states on its outputs. These outputs are connected to whatever circuitry is required by
the application.
The circuits below show typical applications of the MS Series encoder and decoder.
