Tech Lowdown – What sets Sealevel USB serial adapters above the competition?

Sealevel leveraged our military communications experience to develop a rugged USB serial adapter perfect for commercial and industrial environments. We designed the 2105R to operate over wide temperature ranges using the highest quality components and solder alloys. This ensures that the serial signal levels operate in spec over a variety of data rates. The board is mated to a shielded cable and enclosed in a tough, rubberized enclosure, which protects the 2105R from RF and EMI interference. Our SeaCOM suite of drivers and diagnostic utilities provide features beyond the standard serial driver included with your OS. Every unit is 100% quality tested prior to shipping and backed by a lifetime warranty and technical support. If the military trusts our technology in battlefield conditions, you can trust our technology in your application.
