June 2026 | Kongto Technology | Compatibility Matrix
Overview
Okuma OSP (Okuma Sampling Path) CNC controls from the 1990s use proprietary CRT displays in 9-inch, 10.4-inch, and 12.1-inch sizes. The OSP 5000, 5020, and 7000 series are the most common models still in service. Okuma used custom 14-pin and 20-pin connectors that differ from both FANUC and Mitsubishi standards.
