4.1.5.1.5 USB In interface
The USB In interface is a USB 2.0 type B interface that is used to transfer USB data. It must be connected to a USB
interface on the output device (e.g. B&R industrial PC) if DVI operation or SDL operation with a USB type A/B cable
was chosen as the transfer method. For possible transfer methods, see section
"Connection options" on page 17
.
If the interface is connected to an output device (e.g. B&R industrial PC), then USB 2.0 transfer rates are possible
on the USB1 and USB2 interfaces.

4.1.5.1.6 Serial interface
The serial interface is only available for use with a single-touch display in DVI operation. It is used to transfer data
from the resistive touch screen and must be connected to a serial interface on the output device.

4.1.5.1.7 Brightness controls
The brightness controls can be used to set the brightness of the backlight
on the Automation Panel in DVI operation. Buttons have no function during
SDL operation; the brightness can be set via the B&R Control Center, for
example.
