UCC MMI-2 introduction
The UCC MMI-2 controller provides a USB based interface for manual CMMs. The UCC MMI-2 interfaces to the Renishaw digital range of scale readheads, or electrically compatible OEM versions, and to TP20 or similar touch-trigger probes. The UCC MMI-2 controls the collection of scales data, and latches the scales positions when a touch-trigger event is detected. The UCC MMI-2 also supports limited 24 V machine IO signalling, and can interface to a manual head if required.
