General Description

The HydroLynx Model 50388/A2 ALERT2 Data Transmitter uses the HydroLynx ALERT2 Encoder to transmit ALERT2 data reports, implementing the design goals of ALERT2: increased data throughput and flexibility while eliminating erroneous data reports. ALERT2 combines a high baud rate, advanced data encryption with Forward Error Correction (FEC), and Time Division Multiple Access (TDMA) communications.

High baud rate transmissions allow the ALERT2 data packet to include more information than standard ALERT, and FEC ensures reliable RF delivery. TDMA eliminates data report collisions, requiring a GPS antenna/receiver to keep the transmitter clock within its allocated time slot. The GPS time-sync state can itself be transmitted as a data value.

The 50388/A2 uses the same program logic as the proven 50386SLB across ALERT1, ALERT2, and ScadaLynx protocols. It is programmable with the ScadaLynx Toolbox software. Sensor values can be reported in engineering units as unsigned integer, signed integer, single- and double-precision floating point. The ALERT2 Station ID range is 1 to 65,534, with individual Sensor Numbers (0–254) per station. The unit includes a battery-backed RTC and memory, 4 COM ports, USB-A, USB-B, micro SD, and Ethernet. ALERT2 technology has been licensed from Blue Water Design LLC.
