To enhance the USB compatibility it is possible to reduce the speed of the USB 3.1 Gen 2 ports in the BIOS Setup
Advanced>USB Configuration>USB 3.1 Gen 2 Speed.
The default setting of 10 Gbits/s, can be reduced to 5 Gbits/s to be in-line with the USB 3.1 Gen 1 specified data rates.
For the port’s pin assignment, see Chapter 12.3: USB 3.1 Gen 1 and USB 3.1 Gen 2 ( Type A) Port.
4.2.1.4.
USB 3.1 Gen 1 Type A Ports (blue)
The USB 3.1 Gen 1 ports are backwards compatible enabling the connection of USB 3.1/3.0/2.0 compatible devices. The
USB 3.1 Gen 1 specified data rate is up to 5 Gbit/s. For the port’s pin assignment, see Chapter 12.3: USB 3.1 Gen 1 and
USB 3.1 Gen 2 ( Type A) Port.
4.2.1.5.
USB 3.1 Gen 2 Type C Port (cyan)
The USB 3.1 Gen 2 ports are backwards compatible enabling the connection of USB 3.1/3.0/2.0 compatible devices.
For the port’s pin assignment, see Chapter 12.4: USB 3.1 Gen 2 (Type C) Port.
4.2.1.6.
USB 2.0 Ports
The USB 2.0 port (green) supports the USB BIOS flashback function (Figure 17, pos. 7 ). The USB strorage device is
inserted into the USB 2.0 port (green) to update the BIOS, see Chapter 13.3: Using the BIOS Flashback Button. The
second USB port enables the connection of USB 2.0 compatible devices. For the port’s pin assignment, see Chapter
12.2: USB 2.0 Port.
4.2.1.7.
LAN Ports
The dual LAN ports are IEEE1588 capable and enable the connection of Gigabit Ethernet (10/100/1000 Mb/s) devices.
The RJ45 connectors including two status LEDs indicating speed and link activity. For the port’s pin assignment , see
Chapter 12.5: Ethernet Connector.
4.2.1.8.
Audio I/O Ports
The audio barrel connectors are color-coded and enable the connection of High Definition (HD) devices or legacy
devices to be connected to the system. Legacy audio signals are selectable in the BIOS setup menus. The 8-channel
audio port supports audio configurations for 2-channels (headset), 4-channels, 5.1-channels or 7.1-channels
connections. For the correct cabling configuration, see Chapter 12.6: Audio 8-Channel (2, 4, 5.1, or 7.1 Channel
configurations).
4.2.1.9.
S/PDIF Ouput Port
The S/PDIF output is a digital audio optical output for the transfer of high quality audio signals. The signal is
transferred digitally from device to device thus maintaining the quality of the signal as not converted to analogue
before being transferred.
The S/PDIF output is a digital audio optical output. S/PDIF enables high-quality audio signals by transferring the audio
signal digitally from device to device, thus maintaining signal quality as no conversion to an analogue signal is
required before transfer.
To achieve high quality data transfer, Kontron recommends the use of optical cables.
