4.1 Model 8200 ACU:
Legacy-compatible vs. Standard
- The standard Model 8200 ACU is designed to work with the Model 8250 drive cabinet from Radeus Labs. It requires fewer connections and has simpler cabling than legacy systems.
- The legacy-compatible version of the Model 8200 ACU works with a site’s existing GD (Vertex) 7150 drive cabinet and can serve as a drop-in replacement for a GD 7200 unit.
