Trigger discrete actions with button presses by using the MS keyfob transmitter with a compatible receiver and MS Series decoder. The MS Series provides a medium level of security. It lets you send commands from multiple transmitters to distinct receivers in the same vicinity through digital addressing. The remote contains an MS Series encoder and an LR Series transmitter. It can be used with a combination of an MT Series transcoder or MS Series decoder and an LT Series or LR Series RF module.

The encoder uses input from up to five buttons to encode a digital signal, then passes the signal to a transmitter for sending. A receiver picks up the signal and passes it to a decoder. If the signal is accepted, the decoder replicates the encoder’s inputs on its outputs. The outputs can be connected to up to five devices such as microprocessors, LEDs, motors or relays.

Security

The decoder will only accept transmissions from compatible encoders with addresses that match its own. The MS Series has 16,777,216 (224) possible addresses, which makes accidental conflicts very unlikely. Addresses can be configured with button presses.

The MS Series also sends the encoder ID, making it easy to allow or deny access to specific outputs based on which encoder is doing the sending. However, because the MS Series does not use encryption or rolling code, it does not protect against intentional security threats.

Certification

For applications in the United States and Canada, the MS keyfob transmitter is certified at 315 MHz, 418 MHz and 433 MHz by the FCC and Industry Canada. For applications in the European Union, it is CE certified at 433 MHz. That means that as long as the rest of your application is legal, you do not need to certify the remote.

Customization

If you want to customize the appearance of the remote, Linx can accommodate you. Linx offers custom colors (black, gray, white and red), labels, button configurations and cases. Once you tell us what the remote should look like, we need only four to six weeks to send samples and six to eight weeks for production after you approve the samples. Contact Linx for more information about customization.

Benefits

  • Integrate with ease: set up simple remote control systems without a microcontroller or the need for user programming
  • Avoid red tape: no certification needed in the US, Canada or EU as long as the rest of the application is legal
  • Customize appearance: custom colors, labels, button configurations and cases are available
  • Carry conveniently: case hole allows key ring attachment
  • Avoid accidental conflicts: 24-bit address helps prevent identification mistakes
  • Control access to specific outputs: accept or reject certain commands based on the encoder ID
