Sealevel Systems, Inc.
WE LISTEN. THINK. AND CREATE.
In 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.
Our force is using in-house engineering skills to create standard and custom solutions..PRODUCT LINES.
