RENISHAW RMM2 Radio machine module is an antenna that receives the radio signals from the RMP2 and passes the signals through a cable to the MI16 interface.

Two RMM units are supplied with each probe system. This system can be used with a single RMM, but can be vulnerable to 'dead spots' where reflections can cancel out some or all of the radio signals. Each RMM is supplied with 10 metres of coaxial cable to enable the unit to be connected to the MI16 machine interface. An additional antenna extension cable is available in 10 metre lengths. 

The base of each RMM2 incorporates five permanent magnets to allow the unit to be temporarily mounted on a suitable metal surface. Three M4 clearance holes are provided within the base to allow permanent fixing if required.
