The 900 MHz Optex EchoStream EN1941 One-Way Binary RF Module from Invonics is designed to be easily interfaced with your electronic remote application controller (RAC). The RF module allows assimilation of any user-specific application into an EchoStream system. Once integrated with existing products, it provides you with complete EchoStream functionality. The EN1941 one-way binary RF module is an end-device that uses a logic-level connection to interface with your RAC. It can be used in either one-way or two-way EchoStream systems, and features 2 alarm input pins, allowing the use of dual inputs.
The module measures battery voltage every 3.5 hours, and when the battery measures 2.4V, a serial message is sent indicating a low battery condition. It also has an on-board voltage regulator.
