1 About this manual
This user manual was written for professional specialists in electronics and electrical engineering. Its
purpose is to familiarize users with the CMC 430 test set hardware and its specifications.
This manual is supplemented by the "Safe use of the CMC 430" manual, on-site safety regulations
and existing national safety standards for accident prevention and environmental protection.
The CMC 430 test set requires a suitable control software or control device for operation. Please
consult the corresponding getting started manual or user documentation regarding the use of the
controlling software or device.
The "Safe use of the CMC 430" manual and the software manuals are supplied on CD/DVD
together with this user manual.
WARNING
Death or severe injury caused by high voltage possible.
► Operate the CMC 430 only after you have read and fully understood the "Safe use
of the CMC 430" manual.
Safety symbols used
In this manual, the following symbols indicate safety instructions for avoiding hazards.
WARNING
Death or severe injury can occur if the appropriate safety instructions are not observed.
NOTICE
Equipment damage or loss of data possible.

2 Device overview
The CMC 430 is a light-weight multipurpose test set with ultra low-drift signal generators and
measurement inputs. The CMC 430 reaches calibrator accuracy. All inputs and outputs can be
precisely synchronized to UTC using either the Precision Time Protocol (PTP) according to IEEE 1588
or the IRIG-B time code. Synchronization to GPS is possible using the CMGPS 588 accessory from
OMICRON.
The device has a very accurate time base with Stratum 3 specification and is thus able to provide very
high frequency accuracy even without external synchronization.
The CMC 430 is internally controlled by a very powerful digital processor platform that is responsible
for signal generation and measurement. It allows full support of the IEC 61850 protocol for signal
generation and measurement.
All interfaces and indicators of the CMC 430 are positioned on the front plate. Therefore, the CMC 430
can be operated in different positions according to the specific requirements of the application
environment.
The CMC 430 test set itself does not provide any control elements and requires a suitable control
software or control device for operation. The CMC 430 provides the following options for
communication with the controlling software or device:
• Ethernet
• USB
• Wi-Fi (requires a Wi-Fi adapter available from OMICRON)
Device overview

2.2 CONTROL INTERFACE section
All interfaces of this group are touch-safe and reinforced insulated against all other interfaces of the
device. The highest voltage provided is the 53 V Power over Ethernet (PoE) voltage available on the
Ethernet interfaces ETH1 and ETH2, and the accessory ports EXPANSION PORTS 1 ... 4.
2.2.1 Associate button ASC
The CMC 430 can be remotely controlled via an Ethernet or Wi-Fi network. Such
networks provide the possibility to connect more than just one CMC test set.
However, for safety reasons, the operator must be sure to control the test set in front
of him and not to accidentally control any other test set connected to the network.
Therefore, the controlling software will prompt the operator to press the Associate
(ASC) button in order to associate the test set to this computer, before the test set
can be used for the first time.
Please refer to the documentation of the controlling software for information on how
to perform an association.
Pressing the ASC button during the power-up sequence of the CMC 430 resets all
network settings of the CMC 430 (IP configuration, restrictions, Wi-Fi configuration,
etc.). Resetting the IP configuration of the Ethernet ports ETH1 and ETH2 to DHCP/
AutoIP can also be done in the controlling software without restarting the CMC 430.
2.2.2 Status LEDs
The LEDs indicate the system status of the CMC 430 as described below:
S1 (green) S2 (yellow) Status
OFF ON Normal operating state. The test set is ready for
operation and can be controlled by a suitable
software or device.
Blinking slowly OFF The test set is in recovery mode and waiting for a
firmware upload. Refer to the documentation of
the controlling software for information on how to
load a new firmware image to the CMC 430.
ON OFF The firmware upload to the CMC 430 is in
progress.
Blinking fast OFF The new firmware image uploaded before is
being written to the flash memory of the
CMC 430.
Do not turn off the CMC 430 during this state!

2.2.3 Ethernet interfaces
10/100/1000Base-TX Ethernet ports with Power over Ethernet (PoE) capability. The
port LEDs indicate the link speed and will blink in case of traffic:
Link speed LED behavior
10 Mbps Yellow LED active
100 Mbps Green LED active
1000 Mbps Yellow and green LED active
Technical data → Communication interfaces on page 38.
2.2.4 USB ports
The PC port (USB type B) connects the CMC 430 to the USB port of the controlling
computer.
The USB port (USB type A) is currently used for the USB Wi-Fi adapter only. The
USB Wi-Fi adapter is required for connecting the CMC 430 to a Wi-Fi network. Only
use the Wi-Fi adapter available from OMICRON or a Wi-Fi adapter that is certified to
work with the CMC 430.
With future software upgrades, this port could also support other USB devices like
USB memory sticks, for example.
Technical data → Communication interfaces on page 38.
For best EMC immunity, we strongly recommend to exclusively use the
original high-quality USB cable supplied by OMICRON.
2.2.5 External interface
The external interface provides four transistor outputs and two high-speed
counter inputs. The counter inputs are mainly used for meter testing using
different adapters. This interface also allows the connection of the CMIRIG-B
accessory.
Technical data and pin assignment → External interface on page 40.
2.2.6 Expansion ports
The expansion ports allow the connection of up to four external accessories.
Technical data → Communication interfaces on page 38.
