Two-Way Packaged Rain Station

All the effectiveness of the standard ALERT rain station, built on the two-way 50388 Data Transmitter. Besides the ALERT/ALERT2 radio port, two standard serial ports (expandable to six) open multiple communication pathways — GOES on timed and random channels, two-way SCADA over ScadaLynx radios, and leased-line, dial-up, microwave or radio modems. 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)	5354/A2	The one-way sibling on the 50386 platform costs less — see the 5354
Joins an ALERT2 network and needs polling/control	5854/A2	Current NHWC standard plus a two-way return path
Joins a legacy ALERT network with SCADA needs	5854	Matches existing receivers; upgradeable to ALERT2 later
Needs GOES, modem or multi-path telemetry	5854 +OP4	Serial-port expansion opens up to six simultaneous pathways
