SECTION 10
CRT KEYBOARD CONSOLE
This section describes the functions, character
stics, operating procedures, programming con
siderations, and normal operator maintenance of
the DKU9101 CRT Keyboard Console (see Figure
10-1).
FUNCTIONAL DESCRIPTION
The DKU9101 consists of a CRT display unit
with a detachable keyboard unit permitting flex
ibility of operation and placement. The CRT
interfaces with the Level 6 processor by means of
a single Multiple Device Controller (MDC91 0 1)
and a CRT Device-Pac (KCM9101).
Manually entered data and processor-generated
inquiries and responses are displayed on a 12-inch
cathode ray tube. With a display of up to 960
characters (12 lines, 80 characters per line) and a
60 frame-per-second refresh rate, the display
projects clear, bright, easily-read information.
The console keyboard utilizes solid state, high
reliability switches as keys. The keyboard permits
the entry of variable data and program param
eters. The 60 keys can generate 128 characters of
the ASCII code set (see Figure 10-2). The
characters include 26 alphabetic, 10 numeric, and
32 special symbols. Also included are 12 control
keys.
A special entry marker (cursor) appears on the
console display screen to indicate the location of
