3.5.6 Multimedia Port
The multimedia (sound) port is a Dsub9 female with key pin connector. The
multimedia port on the computer provides stereo connections for line input,
microphone input, and line output, which is used for external amplified speakers.
The sound components of the 8570 Vehicle-Mount Computer enable you to record,
compress, as well as play back voices, sound and music. Volume control can be
achieved onscreen through the built-in mixer. See the Windows 98 on-line help for
more information about the volume control.
The heart of the sound system is the AudioDrive ESS Solo-1 chip from ESS
Technology. This chip (the ES1938S) gives you 16-bit stereo audio, and it consists
of an embedded microprocessor, 16-bit stereo A/D and D/A, ESFM music
synthesizer, DMA control, and advanced power management logic. The AudioDrive
is compatible with SoundBlaster, SoundBlaster Pro, and Microsoft Windows Sound
System.
3.5.7 USB Ports
The two USB ports have standard USB 1.1 Amp (total output) connectors. These
ports are used to connect any USB-compatible external devices, such as printers,
floppy drives, etc.
Warning: The USB and ethernet ports are not to be used for typical end user
applications and installations. These ports are designed to be used
for maintenance and setup purposes only. They should only be used
for temporary service connections required for file transfers, set up,
configuration, etc.
3.5.8 PC Card Slots
The 8570 contains a dual PCMCIA interface port compatible with the PCMCIA
version 2.1 standard. It is located behind the cover located on the top right side of
the computer (see Figure 3.5 on page 31). This interface will support:
• two TYPE II cards or,
• one TYPE III card.
The PC card interface is a fully-integrated Cirrus Logic PCMCIA 2.1, 16-bit
controller. Third party PC cards are, for the most part, user-installable.
