The serial port on the rear panel is designated COMA. The COM port designation
is a conventional way to tell your software which I/O (input/output) address to use
in order to send and receive data. These I/O addresses are defined by IBM in their
Technical Reference manuals, and are understood by all popular software
manufacturers.
Audio Sources and Output
Devices
The built-in audio features of your TREK 2 let you record and play back sound
from a variety of sources. These features include:
•
PCI stereo sound that supports Microsoft Windows, Microsoft Sound
System, and most programs that use the SoundBlaster Pro standard.
•
The ability to perform real-time recording with compression and
decompression.
•
Scalable sampling rate (from 4 to 48KHz) and compression ratios that give
complete control of record time to required storage ratio.
•
3-D positional audio DirectX™.
•
Digitally controlled volume with muting.
•
Auxiliary line-in and speaker line-out for maximum flexibility.
•
Built-in microphone and speaker to enhance portability.
To adjust the volume of your internal speakers or speakers attached to the stereo
speaker port, use the volume controls found in your application or in the Windows
Volume Control accessory.
Your computer comes with several software utilities and programs already
installed. Among these is a group of programs which let you control the
computer’s various audio capabilities.
Port Replicator
You may optionally purchase a port replicator for your TREK 2 computer. Rather
than having to detach all your devices every time you take your TREK 2 computer
with you, and then reattach them when you come back, all the devices connect to
the port replicator, which you then connect to your computer through a single port.
Call Micron for more information about the optional port replicator.
You may optionally purchase a USB (Universal Serial Bus) device for your TREK
2 computer. USB devices such as mice, keyboards, and monitors are becoming
more widespread throughout the computer industry.
