CHAPTER

Introduction
The PCM-4898 is an enhanced, all-in-one single board 486 compuer
with an on-board Ethernet interface, local-bus SVGA controller. The
PCM-4898 offers all the functions of an AT-compatible industrial
computer on a single board, but it fits in the space of a 5¼" floppy
drive(only5.75" x 8"). For maximumperformance,thePCM-4898
also supports 2nd level cache sizes from 128 KB to 512 KB (32 KB x
8,64KBx8,or128KBx8).
On-board features include four serial ports (RS-232 and RS-232/
422/485), one parallel port, an enhanced IDE hard-drive controller
(for up to two drives), a floppy-drive controller and a keyboard/PS/
2 mouse interface. The PCM-4898 is also fitted with a composite
video output connector allowing for easy access to your television.
The board's watchdog timer can automatically reset the system or
generate an interrupt if it stops due to a program bug or EMI
problem.
The PCM-4898 also complies with the "Green Function" standard
and supports three types of power saving features: Doze mode,
Standby mode, and Suspend mode.
All display and Ethernet configuration is done through software. A
single Flash chip holds the system BIOS, VGA BIOS and the
network boot ROM function. This minimizes the number of chips
and eases configuration. You can change the display BIOS or
install a boot ROM simply by programming the Flash chip.

LVDS Introduction
LowVoltageDifferentialSignaling is a low noise,low power,lowamplitude
method for high-speed (gigabits per second) data transmission over
copper wire.
LVDS differs from normal input/output (I/O) in a few ways:
Normal digital I/O works with 5 volts as a high (binary 1) and 0 volts as a
low (binary 0). When you use a differential, you add a third option (-5
volts), which provides an extra level with which to encode and results in a
highermaximumdatatranferrate.
A higher data transfer rate means fewer wires are required, as in UW (Ultra
Wide) and UW-2/3 SCSI harddrive, which use only 68 wires. These
devices require a high transfer rate over short distances. Using standard I/
O transfer, SCSI hard drives would require a lot more than 68 wires.
Low voltage means that the standard 5 volts is replaced by either 3.3 volts
or 1.5 volts.
LVDS uses a dual wire system, running 180 degrees of each other. This
enables noise to travel at the same level, which in turn can get filtered
more easily and effectively.
With standard I/0 signaling, data storage is contingent upon the actual
voltage level. Voltage level can be affected by wire length (longer wires
increase resistance, which lowers voltage). But with LVDS, data storage is
distinguished only by positive and negative voltage values, not the
voltage level. Therefore, data can travel over greater lengths of wire while
maintaining a clear and consistent data stream.
