The SUTRON SatLink 3 SL3-XMTR-1 Transmitter offers a reliable and low-cost method of adding GOES satellite transmission capability to almost any datalogger. SL3-XMTR transmits the buffer contents of a data logger to one of many Environmental Satellites for which it is certified. Different operating modes are available ranging from logger control of transmitter setup to scheduling the logger to send a buffer to the transmitter using RS-232 or USB connections. The Transmitter automatically selects the proper RF output power based on antenna selection made by the user. This Transmitter supports the NESDIS GOES 300 and 1200 bps formats as well as formats of other Environmental Satellites orbiting the globe. The Transmitter itself is built upon SUTRON’s 35-year legacy of rugged and reliable GOES Satellite Transmitters. The XMTR provides the user with the highest reliability and leading performance metrics coupled with very flexible programming including scheduled and alarm transmissions. Additionally the transmitter is NESDIS-certified from -40°C to 70°C for all extreme applications demanding long term survivability.
