ES Series RF Transmitter and Receiver Modules Master Development System Rapidly develop hardware and software based on the ES Series transmitter and receiver along with the MS Series encoder and decoder using the ES Series master development system. It comes with two development boards for benchmarking and prototyping, each of which is populated with a transmitter or receiver and encoder or decoder. A large prototyping area gives you a place to develop circuitry. To help you get started, the system also includes antennas, extra modules, connectors, demonstration software and a USB or RS-232 interface for connecting to a PC. When used together, ES Series transmitters and receivers work with MS Series encoders and decoders to let you trigger discrete actions with button presses or contact closures. The ES Series sends or receives digital and analog data including audio at 869MHz or 916MHz. Compared to 2.4GHz modules, narrowband modules from Linx provide longer range and lower current consumption at a more cost-effective price. The MS Series provides a medium level of security. It lets you send commands from multiple transmitters to distinct receivers in the same vicinity through digital addressing. Benefits Benchmark performance: evaluation area lets you test the module in your application environment Develop quickly: prototyping area and PC interface allow rapid development of hardware and software Get help easily: call Linx for free technical support Be creative: send or receive analog and digital data with few legal restrictions 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 System Includes 2 fully assembled development boards 2 ES Series transmitters, including one on the transmitter board 2 ES Series receivers, including one on the receiver board 1 MS Series encoder on the transmitter board 1 MS Series decoder on the receiver board 1 QS Series USB or RS-232 interface module on a daughter board 2 CW Series antennas 4 RP-SMA connectors, including one on each board 1 9V battery 2 AAA batteries Demonstration software with documentation Master development system user’s guide ES Series documentation FCC Part 2 and Part 15 regulations Free technical support
