Malfunctions of the USB2.0 connection if USB
cables longer than 5 m are used.

The maximum USB cable length of 5 m must not be exceeded for the USB2.0
cable!

The general function of non-specification-com‐
pliant USB devices can not be guaranteed,
even if they are working e. g. at the USB inter‐
face directly at the control cabinet PC.
NOTICE
Connect only USB devices that meet the USB specification. The USB devices
that e.g., do not have the specified response times are also commercially avail‐
able.
7.2.6 XSER Interfaces and XVID Interfaces
CDI Interface
The CDI interface is assigned to the two RJ45 female connectors XSER and
XVID. The connection between the control cabinet PC and the operator display
is established on these female connectors via two ready-made cables available
as accessory (see chapter 12.2.4 "Connecting Cable for CDI Interface" on page
73 ).
The CDI interface includes the data interface (XSER) as well as the screen
interface (XVID).
It is dangerous to plug and remove CDI cables
when voltage is applied without using a func‐
tional earth ground for both devices.
NOTICE
The functional earth ground (FE) is always to be used.
Defective screen output caused by exchanging
the VDP device in running operation if the ex‐
changed device has another screen resolution.
NOTICE
The identification of the display resolution is only active once after switching on
the control cabinet PC. That means that if a VDP is plugged and then removed
or if a VDP is connected when starting the control cabinet PC, only a VDP with
the same resolution can be connected again. Thus, it is ensured that the screen
output on the connected VDP is executed automatically without switching the
screen output to the VDP using the keyboard.
