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.

General wiring standards
To achieve reliable operation of the UCC MMI-2 the following should be observed:
All signal cables MUST be screened and all cable screens should be connected electrically to the cable connector's metal shells.
It is recommended that cable screens should only be connected to the functional earth (via the connector shell) of the UCC MMI-2. To avoid
earth loops, cable screens should not be directly attached to the CMM's functional earth.
The grounding must be continuous between all equipment in the installation.
All cable connectors should be secured to the UCC MMI-2 by the connector jack screws (where present).
NOTE: The UCC MMI-2 electronics 0 V rail is connected to the system grounding scheme at a star point within the UCC MMI-2.

Scale interface ﴾3 × 15W HDD sockets﴿
UCC MMI-2 provides a digital interface for Renishaw digital incremental encoders.
UCC MMI-2 can also be used with compatible 3rd party encoders.
Connector details
The ports use 15-way high-density 'D' sockets. The connections for the sockets are shown in the table below.
NOTE: If the machine scale is of a different format (e.g. analogue, single-ended) then this will require an external adaptor.

+V scale can be adjusted independently for each scale interface port.
If the scale power sense wires are connected to the respective scale power supply signals at the readhead, the voltage will automatically adjust
to maintain +5 V at the readhead.
If the sense wires are open circuit then the voltage can be adjusted through the UCCsuite software. In both cases the scale supply voltage is
nominally +5 V and can be adjusted to a maximum of +7 V. The sense and supply signals should be connected as close to the encoder as
possible (see diagram below):
The scale inputs support a quadrature waveform with a minimum edge separation of 50 ns, which equates to 20 million counts per second
with an ideal waveform.

UCC MMI-2 scale error interface circuit
The UCC MMI-2 supports the error signal provided by Renishaw's digital incremental encoders. The UCC MMI-2 can also detect tri-state
conditions on the A and B signals. If the error signal is not integrated into the connected encoder, then the user should connect pin 3 (Error - )
to pin 7 ( +V scale).
UCC MMI-2 scale limit switch interface circuit
If scale limit switch signals are integrated into the the encoder being used then the following diagram should be referenced to ensure
compatibility with the UCC MMI-2.
