6.3 Serial and Parallel Interface Ports
This system comes equipped with two serial ports and one
parallel port. Both types of interface ports will be explained in
this chapter.
The Serial Interface: COM/ COM2
The serial interface port is sometimes referred to as an RS-232
port or an asynchronous communication port. Mice, printers,
modems and other peripheral devices can be connected to a
serial port. The serial port can also be used to connect your
computer with another computer system.
Parallel Interface Port: PRT
Unlike the serial ports, parallel interface port has been
standardized and should not present any difficulty interfacing
peripherals to your system. Sometimes called centronics port,
the parallel port is almost exclusively used with printers. The
parallel port on your system has a 25-pin, DB25 connector.
6.4 Game Port Connector: SOUND
This connector allows you to connect a joystick or game pad for
playing computer games. Also, you may play or edit professional
music by connecting MIDI devices.
6.5 Audio Port Connectors
1. Speaker Out is used to connect speakers or headphones for audio output.
2. Line In
can be connected to the external CD player, Tape player or other audio
devices for audio input.
3. Mic In is used to connect a microphone, which allows you to input sounds and
voices.
