20) SMBus Connector (5-1 pin SMB)
This connector allows you to connect SMBus (System Management Bus) de-
vices. SMBus devices communicate by means of the SMBus with an SMBus
host and/or other SMBus devices. SMBus is a specific implementation of an I

C
bus, which is a multi-device bus; that is, multiple chips can be connected to the
same bus and each one can act as a master by initiating data transfer.

21) Digital LCD Header (20-1 pin DFP) (optional)
This header requires a digital LCD cable connector. For the LCD model, the
individual serial cable with bracket is replaced with the LCD and serial combi-
nation cable with bracket (as shown here). Connect the digital LCD cable to the
LCD header and the serial cable to the COM2 header and mount the bracket to
the chassis on a free expansion slot. NOTE: If both CRT and digital LCD moni-
tors are used, the CRT will take precedent. This connector is for a digital LCD
panel; an analog LCD panel comes with a 15-pin VGA cable connector to be
used on the monitor connector. The connectors with bracket shown here are
provided with the LCD model.
