On November 10, 2006, Sealevel welcomed family, business associates, and friends to the Grand Opening of our 45,000 square foot facility. The occasion also celebrated Sealevel’s 20th anniversary of operations. Events started off with facility tours and then all visitors moved out to the front entrance to listen to speakers and witness the ribbon cutting ceremony.

Building Highlights

  • The new building is over 45,000 square feet
  • This is a 225% increase over our previous facility
  • 15,000 square feet of state-of-the-art ESD tiles were installed to prevent static-electricity damage to high-quality electronic equipment

The History of Sealevel Systems Incorporated

Sealevel Systems Inc. was founded in 1986 by Thomas B. O’Hanlan and Susan D. O’Hanlan, to provide the industry with a quality, well designed and reliable communication adapter for the IBM PC and compatibles. This continued a commitment originated by Tom O’Hanlan, President and CEO, who in 1984 designed the first RS-422/485 communication adapter for the IBM PC.  These types of adapters have found their way into many applications including:

  • The Woods Hole Oceanographic search (and subsequent find) of the Titanic.
  • Space Shuttle Discovery’s chase, capture and repair of the Hubbell Space Telescope.
  • Transmission and reception of encrypted tactical information by U.S. Special Operations forces using ruggedized laptop computers in the battlefield.
  • Downloading of GPS data from aircraft flown by the US Air Force, Navy, and Marines as well as NASA chase and test aircraft.
  • Use by an America’s Cup sailing team to record telemetry data captured during the design phase of a new hull.

Associate Spotlight-18 Years with Sealevel and Still Counting!

Of all Sealevel’s dedicated employees, Rudy Fulgham, has been with the company the longest. Currently Sealevel’s Manufacturing Manager, Rudy has worn many hats over the years including Technician, Design Engineer, and Technical Trainer.

Rudy, how did you become interested in electronics?
Growing up I had family members working with electronics and I’ve been interested in electronics as long as I can remember.  I repaired my first PCB at age 14!

How did you come to work at Sealevel?
I was working for NCR and was introduced to Tom through a mutual acquaintance in the spring of 1988.  I took a part time position repairing PCBs with Sealevel as a second job and loved the work so much that I soon left NCR to come to Sealevel full time.  

What is your favorite customer application you’ve worked with over the years?
That’s a hard one, but I’d have to say working with NASA astronaut Jim Newman who used one of our serial cards on the mission to repair the Hubbell Telescope.  I also really enjoyed working with a engineer turned dairy-farmer on an automated feeding system that measured each animal’s weight and adjusted their feed mix accordingly to maximize milk output.

What makes you most proud of working for Sealevel?
That’s easy.  The reputation we’ve built over the years for not only building the best I/O products available, but also Sealevel’s total commitment to customer satisfaction.

Sealevel Systems is proud to turn the spotlight on Rudy and say, “Thanks for Your Dedication and Hard Work!”
