( SCIENTIFIC e WHEN MEASUREMENTS MATTER s Overview The AL200 is an ALERT2 encoder and modulator that supports ALERT2 and ALERT-concentration services. It meets the ALERT2 standards maintained by National Hydrologic Warning Council (NHWC) and ALERT Users Group (AUG). ALERT2 improves the accuracy and performance of flood warning systems and software, by providing you with faster data transfer, forward error correction, and a TDMA architecture. Benefits and Features ) Easily configurable with graphical, point-and-click software ) Integrated sensor inputs for greatly reduced station cost ) Onboard measurement of supply voltage, clock/GPS quality ) Event or schedule driven reports for battery, clock, tipping bucket, voltage, current, SDI-12, high/low state Detailed Description Channels Available and Their Functions ) P1:Tipping Bucket / Switch Closure Count Accumulator ) SE1:Single-ended Analog Input, millivolt or milliamp ) C1: Digital for limited SDI-12 ) SW12: Switched power for powering sensors / PRODUCT AL200 ALERT2 Ready Improved accuracy and performance for flood warning systems With integrated sensor inputs, the AL200 allows you to create a minimal ALERT2 transmitter/station, decreasing the cost of a typical flood warning system. Combining the AL200 with a Campbell Scientific data logger provides enhanced sensor support, user-defined logic and control, and data logging capabilities. ) Screw terminals for power, radio, and sensors for easy cabling ) Easy access test features for transmission, radio power, and alignment ) Support of encrypted ALERT2 messages; support of 250- millisecond slots ) G: Ground ALERT2 Reporting When used standalone, the AL200 can generate time and event driven reports for Battery, Clock Status, Tipping Bucket, Analog Input (mV or mA), Digital (SDI-12).
