Cirris Roots

Over thirty years ago, Marlin Shelley had grown tired of cables failing in his dot-matrix printers. He wanted a way to guarantee that cables functioned before connecting them. Marlin braided wires together and connected them to a box. He named his invention the Signature 1000 Cable Tester. When Marlin plugged his dot-matrix printer cables into the Signature 1000, the cable tester confirmed whether the cables would work or not.

Word spread of Marlin’s invention and soon other companies wanted cable testers. So Marlin built more Signature 1000s. He left the printer industry and started selling his cable testers. He called his business “Cirris Systems Corp.” and thirty years later Cirris still builds cable testers.

Now as an employee-owned company, Cirris still undertakes Marlin Shelley’s goal of guaranteeing quality cable and harness assemblies. Since the Signature 1000 in 1984 to the easy-wire CH2 today, Cirris has played a role in ensuring the progression of technology.

A 30 Year Company

Cirris founder Marlin Shelley invented the Signature 1000 Cable Tester in 1984. Three decades later customers are still using that original Signature 1000 to test their cables. For these 30 years, Cirris staff and customers have worked together to create cable testers with higher voltages and more capabilities. Ambition and a desire to serve customers have placed over 35,000 cable testers in the hands of more than 7,000 customers on every continent (including Antarctica). People all over the world rely on Cirris when they test cables that help drive cars, heal patients, defend soldiers, even launch satellites. Cirris is proud of our part in helping the world progress toward safety and discovery.

Cirris thanks all past, present, and future customers for the opportunity to serve you. We look forward to 30 more years of providing you with the best cable testing products available.
