KH2 Series RF Transmitter/Encoder and Receiver/Decoder Modules Evaluation Kit Test the performance of the KH2 Series transmitter/encoder and receiver/decoder modules against your own design with the KH2 Series evaluation kit. It comes with two evaluation boards for benchmarking and prototyping, each of which is populated with a transmitter/encoder or receiver/decoder module. A small prototyping area gives you a place to develop circuitry. To help you get started, the kit also includes antennas, extra modules and connectors. KH2 Series transmitter/encoder and receiver/decoder modules let you trigger discrete actions with button presses or contact closures. They contain Holtek chips and LR Series RF modules. The KH2 Series provides a low level of security. It lets you send commands from multiple transmitters to distinct receivers in the same vicinity through physical addressing. Use KH2 Series modules together or with compatible Linx components for reliable one-way wireless communication at 315MHz, 418MHz or 433MHz. Compared to 2.4GHz modules, narrowband modules from Linx provide longer range and lower current consumption at a more cost-effective price. Security The decoder will only accept transmissions from compatible encoders with addresses that match its own. The KH2 Series allows manual addressing through 10 tri-state pins. Because the address is visible in hardware, the KH2 Series is not as secure as the MS Series and HS Series, which use digital addressing. Additionally, because the KH2 Series does not use encryption or rolling code, it does not protect against intentional security threats. Benefits Benchmark performance: evaluation area lets you test the module in your application environment Develop quickly: prototyping area allows rapid hardware development Get help easily: call Linx for free technical support Reduce component count: combined transmitter/encoder and receiver/decoder form a complete module solution with only two parts Integrate with ease: simple hardware configuration lets you transfer raw data without protocol constraints or the need for user programming Save power: low current consumption compared to competing modules extends battery life Avoid accidental conflicts: 310 addresses help prevent identification mistakes Kit Includes 2 fully assembled evaluation boards 2 KH2 Series transmitter/encoder modules, including one on the transmitter board 2 KH2 Series receiver/decoder modules, including one on the receiver board 2 HD Series antennas in the 315MHz kit 2 CW Series antennas in the 418MHz and 433MHz kits 4 RP-SMA connectors, including one on each board 1 CR2032 battery 2 AAA batteries Evaluation kit user’s guide KH2 Series documentation FCC Part 2 and Part 15 regulations Free technical support
