Two-Way Packaged Weather Station

The full weather-station sensor suite on the two-way 50388 Data Transmitter. On-site data analysis processes readings before transmission — averages, maximums, minimums and computed values go over the air instead of raw sample streams, and outside the ALERT protocol the 50388 reports in engineering units with base sets. Commands over the return path are protected by the ALERT2 protocol's encryption and authentication — how two-way networks stay secure →

Which variant do I need?

If your site…	Order	Why
Only needs to report in (one-way)	5381/A2	The one-way sibling on the 50386 platform — see the 5381
Needs polling, remote reconfiguration or control	5881/A2	Two-way SCADA on the current ALERT2 standard
Joins a legacy ALERT network with SCADA needs	5881	Matches existing receivers; upgradeable later
Needs fire-weather or ET data products	5881/A2 +4015	Add solar radiation and let the 50388 compute on site
