The AL205E is a low-power ALERT2 encoder/transmitter with one radio output port for data transmission (TX only). With its two serial ports, input from several devices is possible—including from a data logger. Connection to a data logger enables the acquisition and transmission of hydrometeorological measurements. Local administration is possible through the micro USB console. The GPS functionality provides the required time synchronization needed for TDMA transmissions, and the LEDs offer status and activity indications. The AL205E is firmware-upgradeable.
