DockLink
The most reliable and secure two-way radio transmission system.

Dockmate® uses its proprietary DockLink™ communication protocol. DockLink™ is an infinitely superior, state-of-the-art 2-way Frequency Hopping Spread Spectrum (FHSS) communication with handshake, and GFSK (FM) modulation on the 433 MHz frequency band that provides superior range of 165 feet (50 meters).

Dockmate® operates in the 433 MHz FM frequency band that has 72 communication channels. FHSS means every Dockmate® uses a unique set of 6 channels in the entire band of 72 channels, and then hops from one frequency to another. This FHSS rolling code changes 6x per second over 6 different channels, virtually eliminating any possible chance of interference. 

Three alarms in each handheld remote control Transmitter in the unlikely event that the two-way communication signal with the Receiver is ever lost: Audio (beeping), Vibration, and Visual (flashing LED light).
