12 Introduction
1 Introduction
The purpose of this chapter is to describe the UCC2 (universal CMM controller) and the available options.
1.1 Overview
The UCC2 is a further development in Renishaw’s CMM controller product range. Building on the UCC1
platform introduced over five years ago, the UCC2 offers additional capability and system performance.
The UCC2 further optimises measurement performance through closer probe integration and is suitable
for original equipment and retrofit installations.
With ever tighter tolerances, more complex components and increasing pressures on lead times, the
ability to acquire large volumes of measurement data, both accurately and rapidly, is key to manufacturing
competitiveness. The new UCC2 controller offers advanced adaptive scanning, allowing accurate known
part scanning at velocities limited only by the dynamic performance of the CMM. Speeds of over
500 mm/sec (20 in/sec) can be achieved.
UCC2 offers true multi-sensor integration, giving benefits for original equipment manufacturers (OEMs),
retrofit/re-builders and end-users requiring system upgrades. The controller is supplied configured for
touch-trigger operation and UCCserver™(I++DME) as standard. It can be upgraded to conventional 3axes scanning, Renscan3™, or 5-axis scanning, Renscan5™, by keying in a 16 digit code.
The complete range of Renishaw probe systems is supported; conventional contact, strain-gauge and
analogue scanning sensors, manual and motorised probe heads, probe and stylus changers, and the
latest developments in servo positioning systems. Other optical and video sensors can also be supported.
A key benefit of UCC2 is the simple integration of complex probe systems, for existing systems and future
developments, and is central to Renishaw’s future plans for sensor innovation. Future products will be
easily integrated via plug-in daughtercards, and because the UCC control software is downloaded from
the PC each time the system is switched on, software upgrades for new products are easily integrated.
The UCC2 comprises of a mains-powered controller in a rack-mountable enclosure with a micro-processor
based computer system. It is coupled to the CMM’s host computer by a network link, and to the CMM by
external cable interface connectors.
Introduction 13
The UCC2 CMM controller has the capability of:
• Controlling four axes of a CMM (accepting digital readhead signals and generating four axes drive
motor control signals)
• Accepting input signals from emergency stop, air pressure, crash detector, contactor feedback,
amplifier faults and all axis inner and outer travel limit switches
• Generating seven uncommitted general purpose output signals
• Accepting six uncommitted general purpose input signals
• Providing a +24 V supply for use by the CMM switches
• Directly supporting the TP2, TP6, TP20, TP200 touch-trigger probes, also the SP25M and SP600
analogue scanning probes
• Other Renishaw probes can be integrated into the UCC2 system using plug-in daughtercards
• Directly supporting the Renishaw MCU1 joystick
• Directly supporting the Renishaw SPA2, SPAlite or SPA1 servo power amplifiers
1.2 Literature
A number of other manuals are available to assist with the installation of the UCC2 system and are
included on the UCC software CD ROM. Some of the more relevant ones are listed below:
Part number Title Description
H-1000-5068 SPA1 installation guide System connection details
H-1000-5234 SPA2 installation guide System connection details
H-1000-5058 Renicis installation guide System set-up and testing
H-1000-5057 UCC1 programmers guide Programming
H-1000-5222 Command set Programming
H-1000-5107 SPAlite user’s guide Operation
1.3 CMM host computer
For the installation of a UCC2 controller, the CMM’s host computer must use Windows NT (service pack 6
or later), Windows 2000 or Windows XP Pro as an operating system; a CD-ROM drive, and a hard disc
drive. The storage requirements of the UCC system are less than 500 Mbytes. The processor speed and
RAM requirements are not excessive, if the PC is supporting the operating system and application
software, it will almost certainly support the UCC controller operation.
The PC must have one free dedicated network (Ethernet) connection port available for the UCC2
communication. It is recommended that this NOT a USB plug-in adapter because of the reduction in
speed of operation these devices normally produce.

The power supply has a universal a.c. input circuit. See safety statement at the start of this document.
2.4.2 Output
The UCC2 PSU provides protected low voltage d.c. supplies of +15 V, +5 V and –15 V for external
devices such as scale readheads, the SP600 probe etc.
These supplies share a common 0 V return which is connected at a star point within the UCC2 to the
protective ground of the AC supply and the UCC2 case.
The UCC2 also provides a +24 Vdc supply available for use by the CMM to power the status switches etc.
The return line of this 24 Vdc supply (which should be wired separately from the returns of the +15 V, +5 V
and –15 V supplies) is also connected to the a.c. supply protective ground at a star point within the UCC2.

3 Connecting the UCC2 to the host PC
The following sections detail how to connect and configure the communication link between the UCC2 and
the host PC that is running either the UCC utilities or metrology application software.
3.1 Hardware connection
The host PC must have a dedicated Ethernet connection to the UCC2. It is recommended that this NOT a
USB plug-in adapter because of the reduction in speed of operation these devices normally produce.
If the host PC is also to be connected to a network, it is necessary to install additional hardware within the
host PC to permit a dedicated connection to be available for UCC2 communication. For details on how to
install additional hardware into the host PC, please refer to the PC’s installation / users guide.
The UCC2 is capable of using both 10 and 100 Mbps Ethernet, the selection being determined by the
capability of the network adapter to which it is connected. We recommend that you use a 100 Mbps
network adaptor.
A 5 m Ethernet cable is provided for this link as part of the UCC2 kit and is a Cat 5e, cross-over type.
Other lengths may be used, the maximum being is governed by the generic specification for Ethernet
connections (i.e. a hundred metres), which is sufficient for any CMM installation. It must be a cross-over
type for a single installation.
If you are concerned about EMC disruption due to your environment, or the routing of the cable, then the
use a shielded cross-over cable is recommended.
We suggest that you label your cross-over cable as a cross-over cable as it looks identical to a normal,
not-crossed-over, cable.
3.2 Software installation
The UCC software must be installed on the host PC, prior to connection of the UCC2.
The UCC software disc (A-1333-0080), version 6.0 and later, supports UCC2 installations.
After the software has been installed, one of the utility programs available is “IP Configurer”; which is used
to give the UCC2 an IP address, and establishes the pairing of the PC and the UCC2.
Another software utility that is installed is “Renicis”. It is important that for UCC2 installations you use
Renicis version 6.0, provided on the UCC software version 6.0 CD-ROM, or later versions.

3.3 Configuration of IP addresses
This section describes the steps needed to connect your UCC2 to the host PC and configure the Ethernet
communication link.
NOTE: The examples used in this section are for Windows XP Professional and will vary for other
operating systems.
3.3.1 IP addressing
You have to decide what IP address to give to the UCC2. The key to this is to choose an IP address for
the UCC2 and an IP address for the PC’s network adaptor that are of the same network. What does this
mean? Well, firstly we must introduce sets of networks called network classes which are defined by their
IP address ranges:
class A 1.0.0.1 – 126.255.255.254
class B 128.0.0.1 – 191.255.255.254
class C 192.0.0.1 – 223.255.255.254
For class A networks, a network is defined by the first number.
For class B networks, a network is defined by the first two numbers.
For class C networks, a network is defined by the first three numbers.
If you choose to use IP addresses that belong to the class A network class, then you must be sure that the
first numbers are identical, e.g. 10.0.0.1 and 10.123.4.17. If you choose to use IP addresses that belong to
the class B network class, then you must be sure that the first two numbers are identical, e.g. 155.23.0.1
and 155.23.86.207. If you choose to use IP addresses that belong to the class C network class, then you
must be sure that the first three numbers are identical, e.g. 192.168.32.1 and 192.168.32.2.
A rule that always works is to choose ‘adjacent’ IP addresses from the ranges given above (by adjacent
we mean that the last numbers differ only by 1, e.g. 172.16.40.1 and 172.16.40.2).
NOTE: The last number must not be 0 or 255.
22 Connecting the UCC2 to a CMM
If there is more than one network connection in your PC, choose a network class for the UCC2-PC
connection that is not currently in use to keep the connections clearly separate. To find out which IP
address, and hence which network class your other network interfaces use, type “ipconfig” at a command
prompt. Its output will look similar to this:
Here the UCC2-PC network interface had its cable removed, so shows up as “Media disconnected”. The
other connection was the corporate one, and is seen to be a class B network. Hence the UCC2-PC
network is best chosen to be a class A or a class C one.
3.3.2 Setting the IP address of the PC
The network adapter in the PC to which the UCC2 is connected needs an IP address. See section 3.3.1,
“IP addressing” for a discussion of the choice. How to set the address in the PC varies with each version
of Windows, but the basic idea is the same. Here is the process using Windows XP Professional. You
need administrator rights in order to perform this operation.
a) Select Start → Settings → Control Panel → Network Connections to give:
Connecting the UCC2 to a CMM 23
b) Right-click the appropriate Local Area Connection and select Properties from the resultant popup menu
box to give:
c) Select ‘Internet Protocol (TCP/IP)’ and click Properties to give:
24 Connecting the UCC2 to a CMM
d) If not already selected select ‘Use the following IP address’ and type in the IP address that you want to
use for the PC end of the comms link. Now click in the Subnet mask field. On Windows XP the Subnet
mask will be filled in for you. If you have to fill it in for yourself, here are the values:
Class of network IP address belongs to Subnet mask to use
A 255.0.0.0
B 255.255.0.0
C 255.255.255.0
Leave the Default gateway field blank.
Example:
e) Click OK and then OK again. Whether or not this setting has taken effect depends on the version of
Windows that you are running. On earlier versions you will need to reboot the PC. To be absolutely
sure, reboot your PC anyway.
3.3.3 Setting the IP address of the UCC2
The UCC2 is not intended to be used on a corporate network. It is extremely important that this setting of
the IP address of the UCC2 is on a dedicated connection. It is also important that the connection is not
“firewalled” at the PC end. You need administrator rights in order to perform this operation.
When it is first installed the UCC2 does not have any IP address. Turn the UCC2 on and wait for it to boot
up. It will enter its IP configuration state, shown by the Error LED flashing rapidly. (Please be patient; this
will take about 15 seconds.)
Now start the UCC IP configuration software on the PC.
