Renishaw OMI and OMM Interfaces and Receivers
OMI, OMI-2 and OMI-2T are optical receivers that transmit signals between the probe and CNC control. These interfaces differ from the OMM as they include machine interface circuitry that eliminates the MI12 interface. All three systems offer visual indicators of probe status, start signal status, battery condition and error condition.
OMI is compatible with all Renishaw optical transmission systems including the new OMP60, OMP40 and OMP400 when configured for Legacy transmission (does not work with the OTS).
Part number: A-2115-0001
OMI-2 offers increased resistance to light interference and is exclusively compatible with Renishaw optical transmission systems operating in Modulated transmission mode (OMP60, OMP40, OMP400 or OLP40).
Part number: A-5191-0049 (8 m cable)
Part number: A-5191-0050 (15 m cable)
OMI-2T is identical to the OMI-2 and is the exclusive interface supporting the twin probe system. OMI-2T is capable of communicating with multiple optical probes. CNC must have supporting M codes. This interface should be used when combining an OTS with an OMP60, OMP40 or OMP400.

Part number: A-5439-0050 (15 m cable)
OMM optical machine module
The OMM receiver is required for use with Renishaw optical probes using Legacy transmission. The OMM works exclusively with the MI12 interface.
Part number: A-2033-0576 (25 m cable)
OMM-2 optical machine module
The OMM-2 receiver is required for use with Renishaw optical probes using Modulated transmission. The OMM-2 works exclusively with the OSI. OMM‑2 is capable of communicating with multiple optical probes.
Part number: A-5492-0051 (25 m cable)
RMI radio machine interface
The RMI interface is required for use with Renishaw’s radio transmission probes. The RMI converts RF signals into an acceptable form for the CNC machine control. The RMI has solid state relay output.
Part number: A-4113-0050
