HS Compact Handheld Transmitter Master Development System User's Guide ! Warning Some customers may want Linx radio frequency “RF” products to control machinery or devices remotely, including machinery or devices that can cause death, bodily injuries, and/or property damage if improperly or inadvertently triggered, particularly in industrial settings or other applications implicating life-safety concerns “Life and Property Safety Situations” . NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY SITUATIONS. No OEM Linx Remote Control or Function Module should be modified for Life and Property Safety Situations. Such modification cannot provide sufficient safety and will void the product’s regulatory certification and warranty. Customers may use our non-Function Modules, Antenna and Connectors as part of other systems in Life Safety Situations, but only with necessary and industry appropriate redundancies and in compliance with applicable safety standards, including without limitation, ANSI and NFPA standards. It is solely the responsibility of any Linx customer who uses one or more of these products to incorporate appropriate redundancies and safety standards for the Life and Property Safety Situation application. Do not use this or any Linx product to trigger an action directly from the data line or RSSI lines without a protocol or encoder/ decoder to validate the data. Without validation, any signal from another unrelated transmitter in the environment received by the module could inadvertently trigger the action. All RF products are susceptible to RF interference that can prevent communication. RF products without frequency agility or hopping implemented are more subject to interference. This module does have a frequency hopping protocol built in, but the developer should still be aware of the risk of interference. Do not use any Linx product over the limits in this data guide. Excessive voltage or extended operation at the maximum voltage could cause product failure. Exceeding the reflow temperature profile could cause product failure which is not immediately evident. Do not make any physical or electrical modifications to any Linx product. This will void the warranty and regulatory and UL certifications and may cause product failure which is not immediately evident.

The encoder and decoder are set at the factory to work straight out of the box. To create a new operational setup, follow these steps: On the decoder board, press and hold the LEARN button and then press the CREATE_KEY button to enter Create Key Mode. Release the LEARN button and press the CREATE_KEY button ten times to generate the KEY. Press the GET_KEY button on the back of the transmitter to activate the IR receiver. Hold the back of the transmitter close to the decoder boards's IR key transfer area until the MODE_IND LED turns on. Set Control Permissions by pressing the LEARN button on the decoder board. While the decoder's MODE_IND line is flashing, press each button on the transmitter that is to be granted recognition permission. After all the desired data lines have been transmitted, press the LEARN button again, or wait until the 15 second time-out occurs. The permissions are now saved in the decoder. Transmit with one or all of the authorized data lines to confirm that the learn process was successful. Troubleshooting If the boards fail to work out of the box, then try the following: • Check the batteries to make sure they are not dead and that the antenna is connected. • Make sure the baud rate switch is set correctly on the decoder board. • Make sure the Encryption Key is set correctly. It is created by the decoder and must be sent to the encoder before they can communicate. • Make sure that the Control Permissions are set correctly. If the transmitter has not been set to use a particular line, then when a button on the transmitter is pressed, the MODE_IND LED on the decoder board lights up, but the data line LED does not light up.

By utilizing an advanced serial protocol for data, CipherLinx is able to offer superior noise immunity, greater range, and increased link reliability, all of which are key factors in a wireless system. CipherLinx never sends or accepts the same data twice, never loses sync, and changes codes with every packet, not just every button press. CipherLinx encryption is based on the Skipjack cipher developed by the U.S. National Security Agency NSA , and is widely considered one of the most secure ciphers available. There have been no known successful attacks on the full Skipjack algorithm. Skipjack is a block cipher that has 80-bit keys and 64-bit data blocks. Since each packet is longer that 64 bits, Skipjack is employed in an encryption mode. The particular encryption mode chosen for CipherLinx is based on the CMC encryption mode, so that the resulting cipher is a special kind of function known as a “strong PRP” sPRP . The encryption mode uses several invocations of Skipjack to encrypt the 128 bits in each message. The Skipjack algorithm used by Linx has been proven secure and is not modified to avoid any compromise of strength. CipherLinx is far more than just a Skipjack implementation. CipherLinx's patent-pending technology combines multiple calls to the encryption algorithm with a proprietary mixing algorithm. CipherLinx encryption, as implemented in the Linx HS Series, has been independently evaluated by Independent Security Evaluators ISE , a respected security firm that is widely recognized for its expertise in electronic security. They concluded that “the CipherLinx TM protocol in the HS Series is well-designed and is an excellent choice for applications requiring a secure unidirectional link.” ISE’s full evaluation report can be found at In summary, CipherLinx is a powerful, independently verified, secure encryption technology that is well-suited to a wide range of applications.
