LICAL-XXX-HS001 YYWWNNN HS Series Encrypted Remote Control Encoder and Decoder The HS Series is an ideal encoder and decoder for one-way remote control and Remote Keyless Entry (RKE) applications requiring the highest level of security. The series uses CipherLinx-encrypted remote control technology, which is based on a core algorithm developed by the United States National Security Agency (NSA). This provides a highly secure remote control link while offering numerous innovative features. 0.309 The protocol was evaluated by Independent Security Evaluators (ISE) and they (7.85) 0.026 0.207 (5.25) concluded that the CipherLinx protocol in the HS Series is well-designed and (0.65) is an excellent choice for applications requiring a secure unidirectional link. High Security: The HS Series uses the CipherLinx algorithm, which is based 0.284 (7.20) 0.013 on Skipjack, a cipher designed by the U.S. National Security Agency (NSA). The (0.32) CipherLinx algorithm uses Skipjack in a provably secure authenticated encryption mode both to encrypt 8 bits of button states, a 40-bit counter and 80 bits of integrity protection with an 80-bit key. It never sends or accepts the same packet twice, never loses sync and changes codes with every packet, not just every button press. 0.007 0.030 (0.18) (0.75) Secure Key Generation: The key used by the HS Series is created by the end user through a series of button presses in a truly random fashion. There are no seed values to be programmed into the parts and no list of keys that could be compromised. Everything is held Specifications in the parts. Operating Voltage 2.0 to 5.5VDC Supply Current 370A Robust Protocol: The HS Series uses a robust serial protocol that is far more immune to Power Down Current 0.1A noise and the jitter caused by low cost radios. This equates to a much longer range and better performance within that range than comparable devices. Response Time 67ms Operating 40 to +85C Temperature Range Encoder/Decoder Configuration: The HS Series is configured by connecting pins to supply or ground. There is no software or programming required. Applications More Buttons: The HS Series supports up to 8 data lines that can be connected to buttons, Door and Gate Openers contacts or microcontroller lines. This offers more functionality than many similar parts. Remote Device Control Call Systems Control Permissions: The HS Series can be configured so that certain encoders can only Home / Industrial Automation activate certain outputs on the decoder. This allows the creation of user groups and Remote Status Monitoring relationships rather than an all-or-nothing activation. Lighting Control Encoder PIN: The encoder can be configured with an optional PIN. This 4-button combination must be entered before the encoder will respond to button presses. This adds a layer of security to the physical transmitter as well as having a highly secure transmission. 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 HS Series has extremely low power consumption, making it ideal for applications with a limited power supply, such as a coin cell battery. Revised 4/3/2015Typical Application Circuits When activated, the encoder encrypts 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 decrypts the data. If everything is good, then the decoder replicates the encoders 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 HS Series encoder and decoder. 100k 100k 1 20 LICAL-ENC-HS001 D6 D5 100k 100k 2 19 D7 D4 100k 3 18 SEL BAUD D3 100k 4 17 SEL TIMER D2 5 16 GND VCC 6 15 GND VCC 100k 7 14 From Key Input Port KEY IN D1 100k 8 13 To Transmitter PDN TX CNTL D0 9 12 220 To Transmitter DATA OUT SEND 100k 220 10 11 MODE IND CREATE PIN 100k HS Series encoder 1 20 LICAL-DEC-HS001 D6 D5 10k 2.2k 2 19 D7 D4 3 18 SEL BAUD D3 4 17 SEND COPY D2 100k 5 16 GND VCC 6 15 GND VCC 7 14 From Copy Input Port COPY IN D1 8 13 CREATE KEY D0 100k 9 12 To Key Output Port From Receiver KEY OUT DATA IN 220 10 11 MODE IND LEARN 100k HS Series decoder Ordering Information Part Number Description LICAL-ENC-HS001 HS Series Encoder LICAL-DEC-HS001 HS Series Decoder MDEV-LICAL-HS HS Series Master Development System with LR Series Modules 159 Ort Lane, Merlin, OR, US 97532 Phone: +1 541 471 6256 Fax: +1 541 471 6251 HS Series Encrypted Remote Control Encoder and Decoder www.linxtechnologies.com
