General wiring standards
To achieve reliable operation of the UCC MMI and the CMM host computer, the following should be observed:
Scale readhead signals, reference marks and error signals should comply with EIA RS-422A. It is recommended that each readhead
has its own screened cable and that these cables are kept well away from electrically noisy wiring.
All opto-isolated inputs and outputs should be separate from other connections to the UCC MMI controller, so that the CMM electrical
system is kept isolated from the circuitry within the controller, with the exception of the 0 V reference and protective grounding.
All signal cables MUST be screened and all cable screens should be connected electrically to the cable connector's metal shells. Cable
screens should only be connected to the protective earth (via the connector shell) at the UCC MMI end, and not directly connected to the
CMM protective earth. This is to avoid earth loops. However, the protective grounding must be continuous between the controller and all
other equipment in the installation. All cable connectors should be secured to the UCC MMI by the connector jack screws.
See also the installation instructions supplied with other Renishaw components in the system, i.e. probes or probe heads etc. Particular
attention should be paid to the screening and earthing methods of the cables carrying signals from probes.
NOTE: The UCC MMI electronics 0 V rail is connected to the overall ground plane at a star point within the UCC MMI.
Preparations
Before beginning the installation of the UCC MMI check the following items:
Ensure that all connecting cables, test equipment and software are available
Ensure that the CMM measuring scales / readheads are correctly installed and are functioning
Ensure that all the CMM status and limit switches etc. are correctly installed and have been function checked
Ensure that all power has been removed from the CMM and the host computer

Introduction
The UCC MMI is an interface for use on manual CMMs to interface and connect encoder and probe signals to the PC. The complete range
of Renishaw 2-wire kinematic touch-trigger probes are supported.
The UCC MMI is housed in a 1U 19 inch rack-mountable enclosure. It is coupled to the CMM host computer by a USB 1.1 link and to the
CMM by external cable interface connectors. A rack mounting kit is available as an optional extra.
The UCC MMI has the capability to:
Control three axes of a CMM
Accept input signals from air pressure, contactor feedback and all axis inner and outer travel limit switches
Accept two uncommitted general purpose input signals and generate one uncommitted general purpose output signal
Directly support the TP1, TP2, TP6, TP20 touch-trigger probes
Indirectly support the TP200 via an external PI 200-3 interface
Provide a +24 V supply for use by the CMM if required.

Error
UCC MMI power switched ON
Power on LED is on.
If switch-on is successful the UCC MMI proceeds to the initialisation / test sequence.
Initialisation / test
If the initialisation tests fail, then after about 15 seconds several of the above error LED configurations will indicate the reason for the failure.
NOTE: The normal state after switching the unit on is for the power LED to be lit with all other LEDs off. It only indicates failure if it
remains for more than 15 seconds.
Try switching the controller off, waiting about 10 seconds, then turning it on again. If the problem persists, the unit needs attention.
If the initialisation tests are successful then the power on LED will remain lit and the error LED will start flashing. The controller is now ready
for the system file to be downloaded. System file download occurs via the software connect and configure process in UCCserver.
System file downloading
During system file downloading, the 'power on' LED is on and the 'error' LED is slowly flashing.
If the system file download fails then the 'power on', 'error' and 'system ready' (flashing) LEDs will be on. In this condition, the UCC MMI waits
for a system restart. Switch the controller off and wait approximately 10 seconds to switch it on again.
After a successful download, the system is ready for use and the 'power on' and 'system ready' LEDs will be on.

When the probe is deflected the 'probe seated' LED is off.

Connecting the UCC MMI to a CMM
Switched inputs
Air pressure
The controller monitors the input and will signal to the software if it goes open circuit or high. If not required the input should be connected to
the 24 V return line. See 'Generic UCC I/O connector details'.
NOTE: The polarity of this input can be inverted by the UCCassist set up utility. The default condition is a normally closed circuit,
opening on the event.
Input blanking
Switching polarity can be adjusted in the software or by using hardware. In UCCassist-2 all inputs can have polarity set to normally open or
normally closed.
Pins 13, 14 and 19 - 36 are switchable inputs that are normally open and need to be set to normally closed.
There are two methods for doing this:
1. Connect each pin to pin 37.
2. Switch the polarity of inputs using UCCassist-2 commissioning software.

CMM readhead input connections
TheX,YandZaxismeasuringscalereadheadinputconnectorsarehighdensity15way‘D'sockets.
The X, Y and Z-axis scale readheads of the CMM must be connected to the relevant socket on the rear panel of the UCC MMI enclosure.
Suggestion: Label all readhead connectors to avoid cross connection if removed and replaced in the future.
The three CMM readhead sockets are wired identically, suitable for direct connection to Renishaw RGH2, RGH4 and TONiC ranges of
scale.
NOTE: Other manufacturers' readheads and interpolators may require an external adapter to enable them to use the Renishaw
standard readhead connector wiring. They may also not produce an error signal to the RS-422 specification.
The UCC MMI supplies the 5.25 Vdc power supply for the readheads. If standard Renishaw readhead cables are used, the recommended
cable sizes are 3 m of head cable and 15 m of extension cable, or an equivalent combination. The head cable has 5 times the resistance of
the extension cable.
CAUTION: The connection of the cabling should be such that the CMM movements, as reported by the UCC MMI, are of the correct
polarity i.e. machine movement in a positive direction along any axis should give positive change of position as reported to the host
computer by the UCC MMI controller. Adjust this, if required, by reversing the inputs of the scale readhead signal (change over +A with
+B and -A with -B) or switching polarity in UCCassist-2 commissioning software.
These connectors are supplied pre-blanked for use with UCC MMI.
These are RS422 compatible scale inputs for each of the machine axes through the 15-way HDD connectors.
NOTE: If the machine scale is of a different format (e.g. analogue, single ended) then this will require an external adaptor.

Switched outputs
The UCC MMI has the following uncommitted switched output.
Pin 6 is the uncommitted output available on the UCC MMI I/O connector. The UCC MMI does not directly control the operation of this
output,asitiscontrolledfromtheapplicationsoftwarepackagevia‘command318,Writetocontrollerport'.

when activated. There is an excess voltage protective diode fitted internally to the controller. This output is suitable for driving inputs in the
range 5 V to 24 V.
If the output is not connected to the installation then it should be left open circuit.

USB connection
The host PC is recommended to have a dedicated USB connection to the UCC MMI. Connection to the UCC MMI through a USB hub
causes a reduction in communication speed.
The UCC MMI uses the USB1.1 specification communication link. A 5 m USB cable is provided for this link as part of the UCC MMI kit.
Other lengths may be used; the maximum being 5 m which is governed by the generic specification for USB connections.
When the UCC MMI is connected to the PC and power applied to the unit, Windows will automatically detect the new hardware and start the
Windows hardware installation wizard.
The Windows hardware installation wizard will automatically identify the correct driver for the UCC MMI. This driver is located on the UCC
software installation CD in the drivers' directory.
This is a standard USB type B connector providing the communication connection between the UCC MMI and the PC hosting the
application software.
