2 AWS-842TPB/SPB User's Manual
1.1 Description
The AWS-842 series workstations take advantage of modern
flat-panel displays for minimum size. They can be ordered with
either a color TFT LCD or DSTN LCD display. The AWS-842
offers two types of passive backplane, 3 PCI / 4 ISA / 1 CPU
(PCA-6108P3) and 8 ISA (PCA-6108) slots, 260 watt power
supply, data-entry/function-key keypads, a slim floppy drive,
and two spaces for a hard drive and a slim CD-ROM. A
high-quality steel frame gives security and environmental
protection that meets the toughest industrial standards.
Versatile backplane supply
The backplanes were formed by four-layer PCBs with ground
and power planes for reduced noise and lower power-supply
impedence. They have LED power indicators for +5 V, +12 V,
-5 V and -12 V. The PCA-6108P3 contains three PCI-compati-
ble slots, four PC/AT-compatible (ISA-bus) slots and one
dedicated slot for the CPU card. The PICMG standard and three
power connectors were obtained by PCA-6108P3.
Sealed-membrane tactile-response keypad
You can enter data with the workstation’s two convenient
sealed-membrane keypads, one with 60 data keys, the other
with 20 function keys. An external keyboard can be attached
through a connector on the front panel. A built-in keyboard
interface module merges keyboard and keypad signals into a
single output signal that acts like a standard IBM AT keyboard.
No special software or I/O ports are needed. (Refer to
Chapter 4 page 36 for a detailed description.)
