The DataStation is an always on radio base station that allows you to remotely collect and store data from multiple Em5R data loggers. The Data Station, being always on, receives and saves data from Em5R loggers operating in transmit mode. Data can then be downloaded directly from the Data Station to your computer at your convenience. DataStation data can be graphed and analyzed using ECH₂O DataTrac software.

Features:
• External antenna connector
• RS232 serial cable connectivity
• Storage for over 36,000 broadcast packets
• Flexible 9-24V AC/DC power
• Battery-backed solar power (coming soon)

The Rm1 is a radio modem for communication with the ECH₂O Logger. The Rm1 can be used to query the ECH₂O Logger or as a data relay for extending the range of radio telemetry between the logger and DataStation.
