I recently got a Renishaw MP7 IR probe from eBay. Has there been any further success with reverse engineering the interface? According to the manual that came with my probe it is turned on/off by briefly spinning it at 500 rpm to actuate an internal centrifugal switch. It uses a standard 9v battery. The recommended interface box is an MI7 + OMM. There are reasonably priced MI7 on eBay but the OMM listing are about $1000!
