3.2.1 DVI Extended input
The control panel has a DVI Extended input (X101) according to IP65. It is used to transmit the graphics
signal from the industrial PC to the control panel.
The graphics signal is transferred directly via a DVI cable over a distance of 50m max. Such a cable length
leads to strong distortion of the graphics signal on arrival at the control panel. A signal processor is used in
the control panel to fully restore the DVI signal. The industrial PC requires a conventional DVI output.

Setting the data transfer rate
If the distance between the PC and the control panel is large, the transfer rate for the DDC file must be
limited. The DDC file is transferred from the control panel to the PC to tell the PC the properties of the
display such as timing and resolution.
The VideoBIOS in the graphics card, or in case of on-board graphics the VideoBIOS in the motherboard,
contains the definition of the transfer rate for the DDC file. This value must be 50kHz or less. If this value is
too high, the image is either not displayed or only displayed after Windows starts.
Windows graphic drivers also contain a value for the transfer rate of the DDC file. If no image is displayed
under Windows, a graphic driver must be used that contains a value of 50 kHz or less for the DDC file
transfer.

The plug for the power supply is specified for 16A and can accommodate wire cross-sections of up to
0.75mm2. For long supply lines, use 0.75 mm2 cables to achieve a low voltage drop on the supply line.
There should be at least 22V at the power supply plug of the control panel, so that the control panel remains
switched on during voltage fluctuations. The plug is included in the delivery. You can obtain a replacement
plug from your Beckhoff Sales using the following ordering option:
• C9900-P916: power supply connector for CP79xx, round connector IP65 with strain relief for the
external supply cable
3.2.3 USB Extended 2.0 input
The control panel has a USB Extended 2.0 input (X103). The control panel is connected to the CU8801
USB-to-USB Extended converter box via the interface. The interface transmits USB 2.0 with 480Mbit/s.
To realize a distance of 50m without hubs, USB Extended 2.0 (USB-E 2.0) converts the USB signal so that
it can be transmitted via a 50m CAT-5 cable. In the control panel the signal is converted back to USB. This
is not an Ethernet connection. No Ethernet switch or hub can be integrated in the USB Extended 2.0 cable.

CP79xx-14xx18 Version: 1.0
4 Commissioning
To use the control panel, you must first put it into operation. The first step is to transport the device to is
operating location and unpack it. This is followed by mounting the device on the mounting arm, connecting
the cables and power supply, and finally switching on the control panel. Since the control panel does not
have its own power switch, switching the power supply on and off also switches the control panel on and off.
Operating the control panel
The control panel is operated via the touch screen.
NOTE
Damage to the touch screen
Operating the touch screen with unsuitable objects may damage the touch screen.
• Only operate the touch screen with your bare finger or with your finger using a suitable glove.
• If you use gloves, make sure that no hard particles such as metal shavings, glass splinters or similar ad-
here to the glove.
If you, as the user, require additional protection for the touch screen against dirt and scratching, for example
due to dirty hands, this can be achieved with a Beckhoff protective film. The film provides short-term
protection for a few days.
You can either order your device directly with the protective film applied or order a film individually and apply
it yourself. Please refer to the price list for the available protective films according to the display size of your
device.
Proceed as follows to attach the protective film to the touch screen:
1. Ensure that the environment is as dust-free as possible.
2. Thoroughly clean the surface of the device to be fitted with the film and remove all grease residues.
3. Detach the film from the backing at the short edge and place it on the surface.
4. Gradually remove the film from the backing. At the same time, use a doctor blade or other object with a
soft rubber or felt edge to apply the film.
5. Brush away air bubbles towards the edge with a doctor blade or other object with a soft rubber or felt
edge.
ðYou have mounted the protective film.
If you want to remove the protective film again, you must proceed with caution so as not to damage the
touch foil, which is located between the glass pane of the control panel and the applied protective film.
To remove the protective film, proceed as follows:
1. Carefully loosen one corner of the protective film.
2. Carefully pull the protective film off the control panel at the loosened corner at as flat an angle as
possible.
ðYou have removed the protective film.

4.1 Transport and unpacking
The specified storage conditions must be adhered to (see chapter 8 Technical data [}29]).
Despite the robust design of the unit, the components are sensitive to strong vibrations and impacts. During
transport the device must therefore be protected from mechanical stress. Appropriate packaging of the
control panel, in particular the original packaging, can improve the vibration resistance during transport.
NOTE
Hardware damage due to condensation
Unfavorable weather conditions during transport can cause damage to the device.
• Protect the device against moisture (condensation) during transport in cold weather or in case of ex-
treme temperature fluctuations.
• Do not put the device into operation until it has slowly adjusted to the room temperature.
• Should condensation occur, wait for about 12 hours before switching the device on.
Unpacking
Proceed as follows to unpack the device:
1. Check the packaging for transport damage.
2. Remove packaging.
3. Keep the packaging for possible future transport.
4. Check your delivery for completeness by comparing it with your order.
5. Check the contents for visible shipping damage.
6. In case of discrepancies between the package contents and the order, or in case of transport damage,
please inform Beckhoff Service (see Chapter 9.1 Service and Support [}30]).
