Second Serial Port
The mainboard has a connector for an optional second serial port. You
can implement the second serial port by connecting an extension bracket
with a serial port to the onboard serial port connector COM2.
COM2
Note:
An second serial port may use some of the resources
required by an infrared port or a fax/modem card. If you have
more than one of these items installed, you may not be able to
use them at the same time. You can use the Peripherals page of
the setup utility to switch resources between an IR port and a
second serial port. See Chapter 3 for more information.
Digital Audio Extension Bracket
You can purchase an optional 24-bit digital audio extension bracket from
a third-party vendor. You can use the audio RCA jacks to connect to
digital audio devices. If your CD-ROM/DVD drive has digital audio
output, you can connect it to the input pins of the SPDIF connector.
On the mainboard, locate the digital audio connector SPDIF1. Connect
the cable from the digital audio extension bracket to SPDIF1. If you have
digital audio output from your CD-ROM/DVD drive, connect it to the
marked audio input pins.
