Chapter 3: Motherboard Connections
HDMI Port
The HDMI (High-Definition Multimedia Interface) ports are used to display both high definition
video and digital sound through an HDMI-capable display, using the same cable.
Universal Serial Bus (USB) Ports
There are two USB 3.0 ports (JUSB1) on the I/O back panel. The motherboard has two
additional USB 2.0 connections via the JEIO1 header. J6 also provides two front panel USB
2.0 connections. The onboard headers can be used to provide front side USB access with a
cable. Two USB 2.0 cables for front panel support are included with the motherboard.
JDC
This is a DC jack that functions as the 12V power connector.
