HS Long-Range Handheld Transmitter Master Development System Rapidly develop hardware and software with the HS long-range handheld transmitter master development system. It comes with two remotes and a development board for testing and prototyping. The board is populated with an HS Series decoder and LR Series receiver. A large prototyping area gives you a place to develop circuitry or use a different RF module. To help you get started, the system also includes an antenna, extra modules, connectors, demonstration software and a USB interface for connecting to a PC. When used together, HS long-range handheld transmitters work with HS Series decoders and compatible Linx RF modules to let you trigger discrete actions with button presses from up to 1,000 feet away. The HS Series provides a very high level of security. It lets you send commands from multiple transmitters to distinct receivers in the same vicinity with state-of-the-art protection against intentional security threats. The remote contains an HS Series encoder and an LR Series transmitter. It can be used with a combination of an HS Series decoder and an LT Series or LR Series RF module. The encoder uses input from up to eight 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 eight devices such as microprocessors, LEDs, motors or relays. Security The HS Series uses CipherLinx®, an extremely secure protocol that received a glowing review from the Independent Security Evaluators. It protects against intentional security threats such as the following: Code scanning: trying every possible address. CipherLinx® uses an 80-bit key that makes code scanning impractical. At eight keys per second, it would take about 4,789 trillion years to try every one. Code grabbing: recording a transmission to replay later. With CipherLinx®, every transmission is unique. Old transmissions are not accepted, so code grabbing doesn’t work. Copy-paste attack: recording a transmission, then modifying the data and sending it again. CipherLinx® makes sure the data was received intact with an 80-bit integrity check. If the data was compromised, it ignores the transmission. Encryption attack: cracking the encryption algorithm. CipherLinx® uses Skipjack, a highly secure algorithm with no known vulnerabilities combined with a certified mixing algorithm to create a 128-bit cipher. Theft: stealing the remote control. An optional keypad PIN keeps stolen devices from being used. Uniqueness and Identification The decoder will only accept transmissions from compatible encoders with keys that match its own. The HS Series has over a million billion billion (280) possible keys, which makes accidental conflicts nearly impossible. Key generation can be configured with button presses.
