The incorporation of eight data lines is another advantage. All encoders provide at least one input line which is usually connected to a switch or contact. It is often advantageous to have multiple buttons or even a keypad matrix. Linx products incorporate eight data lines for maximum versatility. Next, the modules are optimized for certification. Linx encoders and decoders are designed to maintain a maximum 50% duty cycle across all possible packets. This makes certification easier and allows greater output power, resulting in better range and more reliability within that range. The Linx modules simplify true random addressing. CipherLinx® populates the key using true human randomness. Setup is a simple one-time task of pressing a button. This avoids having to set DIP switches or program key seeds in production. It also avoids the inconvenience and vulnerability of having to maintain a list of seed values. The key is completely unknown even to the manufacturer.
