Comprehensive Software Solutions and Support
Our full array of hardware is backed by powerful software that makes implementation easy. Each Sealevel product ships with a comprehensive software suite providing drivers, setup files, samples, and application notes. Most popular operating systems are supported including Windows 95/98/ME/NT/2000/XP, QNX, and Linux. For help installing serial products, diagnostic software is supplied such as loopback tests, bit error rate testing (BERT), and throughput monitoring. All of Sealevel’s digital I/O products are now supported through our OPC driver, making connection to a variety of third-party software packages simple.


Long-Term Availability
Sealevel is committed to providing long-term availability of all of our products. In fact, we still produce a variety of boards that date back to the 1980s. We work closely with our vendors to insure component availability and in instances that a component becomes obsolete we strive to design a “form, fit, and function” replacement that works transparently to the customer.
