Our Story

n 1984, Tom O'Hanlan designed the first RS-422/485 communication adapter for the IBM PC. From that moment of inspiration, Tom and his wife Susan saw an ever-growing industry-wide need - and began work to fulfill it. In 1986, they formed Sealevel Systems, Inc. committed to providing reliable, well-designed communication adapters for the IBM PC and compatibles. Why the name Sealevel? Tom wanted a name that didn't sound like a computer company. After listening to music (his other passion), the word Sealevel came to Tom's mind. In a serendipitous coincidence, the jazz/blues/rock band that had once backed The Allman Brothers Band, released their self-titled debut album in 1977. Their name? Sea Level. In 1986 Sealevel the company was born. Today, Sea Level bandleader and acclaimed keyboardist, Chuck Leavell, is the celebrity spokesperson for Sealevel Systems, Inc. and Tom's trusted friend. More than 20 years later, Sealevel continues to provide innovative, reliable hardware and software products to enable computer connectivity and control.
