5.4.2 DisplayPort (N011)
The DisplayPort transfers image and audio signal at the same time and is therefore suitable for connecting
panels or monitors to the Embedded PC.
Fig.8: DisplayPort X300.
Version 1.1a of the DisplayPort (DisplayPort++) is installed on the Embedded PC. Adapters from DisplayPort
to DVI-D or DisplayPort to HDMI can be used to connect monitors without DisplayPort to the Embedded PC.

5.4.3 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.
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.
