The cable connection to the head uses a standard 15-way high-density D connector. The cable should be connected and terminated as detailed below. It is mandatory that the Renishaw universal machine cable is used.

Various lengths of cable are available and include pre-crimped options for ease of installation.

The following image shows the pin numbers for each connector end view of the Renishaw universal machine cable.
