Interfaces and Connectors
Lion (VL-EPMe-42) Reference Manual 30
DisplayPort
The two Displ+ (DP++) connections provided use two 20-pin mini DisplayPort connectors.
DisplayPort consists of three interfaces:

Main Link – transfers high-speed isochronous video and audio data.

Auxiliary channel – used for link management and device control; the EDID is read over
this interface.

Hot Plug Detect – indicates that a cable is plugged in.

Console Redirection
The Lion board can be configured for remote access by redirecting the console to a serial
communications port. The BIOS Setup utility and some operating systems (such as MS-DOS) can
use this console for user interaction.
The default settings for the redirected console are 115.2 kbps, 8 data bits, 1 stop bit, no parity,
and no flow control.
