PRODUCT
DESCRIPTION
The SUPER BEE Computer Terminal shown
1 Figure 1-1,
is
a self-contained, operator controlled
~mote
display terminal
with
a detached ANSI key-
oard.
The
terminal
is
designed
for
use
in serially
·ansmitting
information
to, and receiving
information
·om,
an
interconnected data source. The terminal
will
perate
to
exchange data
at
any
of
several preselected
ransmission rates;
9600
baud
maximum.
The SUPER BEE employs a 12-inch (measured
liagonally) rectangular television
type
monitor
which
s implemented
to
display up
to
25 lines
with
80
charac-
:ers.
Each character
is
generated
from
a 5-
by
7
-dot
natrix
with
two-dot
spacing between adjoining characters.
The
SUPER BEE Terminal
has
a detached key-
board interfaced
to
the display
unit
by
means
of
a flex-
ible
4-foot
cable. The keyboard employs the N-key roll-
over feature. When any alphanumeric key
is
held down
for
longer than
half
a second,
it
automatically
repeats
at a rate
of
approximately
25 characters per second.
Some
of
the
control
keys also
auto
repeat, however auto
repeat
has
been
inhibited
where
not
meaningful.
Interfacing
is
accomplished via the rear panel
connectors. The
Input/Output
and
Printer
connectors
are connected in parallel and
will
interface most standard
serial ASCII printers. The
printer
data
can
be
transmitted
at
a separate baud rate
from
that
of
the terminal and may
1 - 1
be
adjusted
from
110
to
9600
baud. A Video connector
is
provided
for
connection
to
a remote display
monitor.
The
output
from
this connector
is
a composite video signal
capable
of
driving
1000
feet
of
50-ohm coaxial cable.

Modes
of
Communication
Half-Duplex/Full-Duplex
Transmission
The SUPER BEE Terminal may
be
operated
off-line
or on-line. A rear panel switch allows the
operator
to
select either half-duplex
(HDX)
or
full-
duplex (FOX) communications. Reset key must
be
depressed
following
FDX/HDX
selection. Full-duplex
operation allows data
to
be
transmitted
with
each
key-
board
entry
wherein the terminal's receiver
input
is
enabled
for
immediate
computer
reply
of
the trans-
mitted
data (echoplex)
to
verify
proper receipt
of
data.
Half-duplex data transfer
is
generally
used
for
sending
precomposed
messages,
either a
few
lines at a
time
(block
mode)
or
an
entire
memory
dump
at a
time
(page mode). While
transmitting
data in either the
page
or
block modes,
both
the keyboard and the
receiver inputs
are
disabled. Operation in the
off-line
mode allows the operator
to
edit
the
message
before
block transmission
of
the data. Operation in the
on-line mode enables the
transmitter
and the receiver.
Synchronous
or
Asynchronous Transmission
The SUPER BEE Terminal allows the selection
of
either serial synchronous
or
serial asynchronous
transmission. During synchronous operation, the
word
structure consists
of
eight bits;
seven
data bits
and a
parity
bit.
Synchronization
is
accomplished
by
receiving and
identifying
two
or
more sync codes
at
the
beginning
of
a transmission; synchronous
operation
is
not
possible during conversational
type
transmission (character
by
character). The asynchro-
nous
word
structure consists
of
a start
bit,
severi data
bits, a
parity
bit,
and one
or
two
stop bits (One
stop
bit
