2.1 Intended use
The CX9020 Embedded PC is a control system designed for installation on a DIN rail in a control cabinet or
terminal box. The Embedded PC series is used in conjunction with Bus Terminals for recording digital or
analog signals from sensors and transferring them to actuators or higher-level controllers.
The Embedded PC is designed for a working environment that meets the requirements of protection class
IP20. This involves finger protection and protection against solid foreign objects up to 12.5 mm, but not
protection against water. Operation of the devices in wet and dusty environments is not permitted, unless
specified otherwise. The specified limits for electrical and technical data must be adhered to.
Potentially explosive atmospheres
Device modification CX2900-0107 is mandatory for operation of the Embedded PC in potentially explosive
atmospheres, zone 2/22. The device modification includes a factory-installed retainer bracket for
mechanically securing the plug connectors.
The device modification is mandatory for operating the Embedded PC in the following potentially explosive
atmospheres:
1. For Zone 2 atmospheres in which gas is present as a combustible material. Zone 2 means that an ex-
plosive atmosphere does usually not occur during normal operation, or only for a short time.
2. For Zone 22 atmospheres in which dust is present as a combustible material. Zone 22 means that an
explosive atmosphere in the form of a cloud does usually not occur during normal operation, or only
for a short time.
The Embedded PC must be installed in a housing, which ensures protection class IP 54 for gas according to
EN 60079-15. A housing with protection class IP 54 is required for non-conductive dust. IP 6X is required for
conductive dust according to EN 60079-31.
Improper use
The Embedded PC is not suitable for operation in the following areas:
• In potentially explosive atmospheres, the Embedded PC may not be used in other zones except for
2/22 and not without a suitable housing.
• Areas with an aggressive environment, e.g. aggressive gases or chemicals.
• Living areas. In living areas, the relevant standards and guidelines for interference emissions must be
adhered to, and the devices must be installed in housings or control boxes with suitable attenuation of
shielding.

2.3 Safety instructions
The following safety instructions must be followed during installation and working with networks and the
software.
Explosion protection
Device modification CX2900-0107 is mandatory for operation of the Embedded PC in potentially explosive
atmospheres, zone 2/22. The device modification entails the modification and relocation of the device label
and a factory-fitted retainer bracket for mechanically securing the connectors.
WARNING
Operation without device modification
Without the CX2900-0107 device modification, the USB plug connectors may slip out of the USB ports due
to vibration, which may trigger a deflagration or explosion.
The Embedded PC must only be used with the device modification, and the USB plug connectors must be
secured to the retainer brackets with cable ties.
Tighten the screws of the DVI plug connector and, if present, also the screws of the fieldbus plug connectors,
in order to prevent the plug connectors slipping out. Only use RJ45 connectors with an intact latch. Use
cable ties to secure the USB plug connectors and RJ45 connectors to the retainer brackets.
The CXxxxx-N020 optional interface (audio interface) may not be used in potentially explosive atmospheres.
The Embedded PC must be installed in a housing, which ensures protection class IP54 for gas according to
EN 60079-15. A housing with protection class IP54 is required for non-conductive dust. IP6X is required for
conductive dust according to EN 60079-31.
Observe the temperature at the cable entry points into the housing. If the temperature during nominal
operation is higher than 70 °C at the entry points or higher than 80 °C at the wire branching points, cables
must be selected that are designed for these high temperatures and operation in potentially explosive
atmospheres.
Maintain the prescribed ambient temperature during operation. The permissible ambient temperature lies
within the range from 0 °C ... +60 °C.
Take measures to prevent the rated operating voltage exceeding 119 V through short-term interference
voltages.
Switch off the power supply and ensure that no explosive atmosphere occurs when:
• Bus Terminals are connected or removed,
• the Embedded PC is wired or cables are connected,
• the front flap is opened,
• the CFast card, MicroSD card or battery is replaced.
Mounting
• Never work on live equipment. Always switch off the power supply for the device before installation,
troubleshooting or maintenance. Protect the device against unintentional switching on.

5.2 Ethernet RJ45 (X000, X001)
Both Ethernet interfaces are switched and independent of each other. Please note the following points for an
Embedded PC with switched Ethernet interfaces:
• The Embedded PC may not be connected to a local network if at the same time EtherCAT is operated
via the second EtherNET interface. The EtherCAT telegrams (broadcast) disturb the local network, the
consequence being that the Embedded PC can no longer be reached via a host PC.
• No additional switch is required for a line topology.

A DVI-D to VGA adapter cannot be used
The DVI-D interface transfers digital data and is suitable for connecting a digital display. The resolution at the
display or the Beckhoff Control Panel depends on the distance from the display device. The maximum
distance is 5 m. Beckhoff offers various Panels with an integrated "DVI extension". These make a cable
length of up to 50 meters possible.

The Embedded PC also supports higher resolutions, based on the DVI standard. A maximum resolution of
2560 x 1440 pixels can be set on the Embedded PC. Whether this resolution is achieved depends on the
monitor, the cable quality and the cable length.

5.4 Optional interfaces
5.4.1 Audio interface (N020)
Two inputs are available: "LINE IN" (X300) and "MIC IN" (X301). The "LINE OUT" interface (X302) is
intended for audio signal output. The 3.5 mm sockets are designed for jack plugs. It can also be used for
connecting headphones with a maximum output of 200 mW.
Fig.9: Audio interface X300, X301, X302.
The audio interfaces are accessed via the operating system.
The audio interface operates in stereo mode as standard, using stereo outputs/inputs and a single-channel
input for the microphone. The inputs should be connected as indicated.
Line In / Line Out jack plugs
The left channel is transferred via the tip of the jack plug, the right channel via the first ring. The remainder of
the sleeve is used for earthing.
