The AL200 is an ALERT2 intelligent network device (IND) developed by Campbell Scientific, Inc. Portions of embedded code were developed and copyrighted by Blue Water Design LLC and are used under license. It is an encoder, modulator, and sensor interface designed for use both as a stand-alone device and as a peripheral to a Campbell Scientific datalogger or third-party Data Collection Platform (DCP). This device uses the Automated Local Evaluation Real Time Protocol version 2 (ALERT2) and can operate as both a remote ALERT2 transmitter and as an ALERT to ALERT2 concentrator and repeater.
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 datalogger provides enhanced sensor support, user-defined logic and control, and datalogging capabilities.Read More
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 or High/Low State).

A standalone AL200 can measure:
A software utility used to configure the ALERT210 and AL200.
Current AL200 ALERT2 operating system. Requires the Device Configuration Utility to update the operating system in the AL200.
AL200 USB Drivers for the Windows operating system. 32 and 64 bit support for Windows 8, Windows 7, Windows Vista and Windows XP.
Note: Drivers should be loaded before plugging the AL200 into the computer.
