SMBUS

The System Management Bus (SMBus) is a two-wire interface through which simple power-
related chips can communicate with rest of the system. It uses I2C as its backbone.

A system using the SMBus passes messages to and from devices instead of tripping individual
control lines.

With the SMBus, a device can provide manufacturer information, tell the system what its model/
part number is, save its state for a suspend event, report different types of errors, accept control
parameters, and return its status.

The SMBus may share the same host device and physical bus as ACCESS bus components provided
that an appropriate electrical bridge is provided between the internal SMB devices and external
ACCESS bus devices.

LCD

There are two LCD panel interfaces provided on the SBC-845D-VEA: TMDS and LVDS.

TV

Composite Video, S-video and Scart R/G/B interfaces are 3 kinds of TV outputs provided by this
system. Please refer to connector J30 for more details. Each time the system is on, the system
auto-detects one interface for outputting display information. A connection to different
interfaces will result in a particular impedance combination of signal lines. The selection will be
made based on the different impedances of each signal line.
