INTRODUCTION
This manual provides a general
equipment
des
cription
and
operating
instruction
for
the
Bee
hive
8150
series
video
terminals.
Included
are
sufficient
diagrams,
tables
and
descriptive
text
to
provide an understanding of
the
operational
characteristics
of
the
equipment.
A brief equip
ment
description/option list, installation with
setup
procedures,
and
operating
instructions
are
included
in
three
general
sections.
Section I provides a brief description of
the
8150
series
ternriinals
and
a
brief
summary
of
the
differences
between
the
8150
series
termi
nal
models.
Section
II
describes
the
installation
and
initial
checkout
of
the
terminal.
Section
111
describes
the
operational
character
istics
and
functions
of
the
terminal.
The
Beehive 8150 series
units
(see Figure 1-1)
are
low-cost
multi-feature
remote
video
display
terminals.
The
terminals
are
self-contained,
operator oriented, and computer accessible.
The
Beehive
8150
series
are
attractively
styled
sophisticated electronic packages, designed for
use in serially transmitting information
to
and
receiving information from an interconnected
data
source.
The
terminals
are
fast,
with
an
operational exchange of data at any
of
several
preselected transmission rates —75 to 19200
baud.
Other
features
include
cursor
control,
lower
case
descender
characters,
and
an
auxil
iary interface. In addition. Block Send, Aux
iliary Send, editing, formatting, blinking, and
16 special function keys are some of
the
fea
tures
available in
upper
level
terminal
con
figurations.
1-1
The 8150 and 8157 terminals are packaged in a
single-piece housing; the 8152 features a two-
piece
housing,
allowing
the
keyboard
to be
removed.
The
8157 capabilities have been
expanded
to
provide
a
programmable
keyboard
and
Pl-A
program
changes,
making
it capable of
communicating and operating with most time-
share
systems.
The
Beehive
8150
series
are
controlled
by an
operator-designed
keyboard
employing
N-key
rollover feature. When a key is held down for
longer
than
half
a
second,
it automatically
repeats
at a
rate
of 15
characters
per
second.
Autorepeat on some keys is inhibited where not
meaningful. Keyboard features include an
11-key
numeric
pad
for
convenient
entering
of
numbers; cursor up, down, right and left con
trols;
and
optional
function
keys
with
edit
and
data
transmit
keys.
Interfacing,
baud
rate
selection,
half
and
full
duplex
switching,
and
video
controls are
conven
iently
arranged
on the
rear
panel.
(Full
duplex
operation
allows
datato be
transmitted
with
the
terminal'sreceiverinput enabled for immediate
computer
reply
ofthe
transmitted
data
[echo-
plexed]
to
verify
proper
receipt
ofthe
data)
The
Input/Output
and
auxiliary
I/O
connectors
will
interact with most standard
serial
RS232C
external
devices. Data from
the
auxiliary port can be re
ceived
and
transmitted
at
a
baud
rate
separate
from that of the standard
I/O
Port. The baud
rate of the auxiliary port is strap selectable.
The
CRT
is a 12-inch/30.5 cm {measureddiagon
ally),
digital
type
monitor
which
is
formatted
to
display 24 lines with
80
characters
on each line,
for a total page
memory
of 1920 characters. Each
character
is
generated
from
a 5 x 7
dot
matrix,
with
two-dot
spacing
between
adjoining
characters
and a one-scan spacing between
adjacent
lines.
The
standard
character
set
consists
of
95
display-
able
characters.
The
character
set
includes
lower
case
character
descenders
(e.9.,
y, g,
etc.).
Each
terminal

SECTION
OPERATION
3.1
INTRODUCTION
This
section
provides
basic
operating
instructions
for
the
B150
series
computer
terminals.
To
operate
these
terminals
efficiently,
the
operator
should
be
familiar
with
instructions
contained
in
this
section.
The
B150 series
terminals
should
be
properly
in
stalled in
accordance
with
procedures
outlined
in
Section
II
of
this
manual.
3.2
OPERATOR
CONTROLS
The
keyboard
and key explanations
are
shown in
Figures 3-1
and
3-2
Operation
of
any
key
on
the
keyboard
causes
either
character
codes,
control
codes,
or
escape sequences
to
be generated.
The
type
of
code
selected
by
the
operator
is
deter
mined
by
the
key
or
sequence
of
the
keys
which
have
been
depressed.
There
are
three
keys
that
are
used
in a
sequence
with
any
alphanumeric
key:
To
perform
an Escape
operation,
depress
and
release
the
BSC key,
followed
by
the
desig
nated
alphanumeric
key
(see Figure 3-2).
To
perform
a
Control
function,
depress
the
CTRL
key
and
hold
this
key
down
while
simultaneously
typing
the
alphanumeric
key.
If
the
upper/lower
case
option
is selected,
the
SHI
FT
key
is
used
to
generate
upper
case
codes
and
is
operated
the-
same
as a
type
writer
shift
key.
Some
Control codes, generated by depressing a
Function key,
produce
a single 8-bit
code
which
is
acted
upon
but
not
transmitted,
e.g.,
cursor
move
3-1
ment
controls,
SEND,
CHARACTER
DELETE,
etc. The Escape or Control codes generated by de
pressing
the
ESCor CTRL keys and an alpha
numeric
key
produce
two
7-bit
codes
which
are
acted
upon
and
also
transmitted,
e.g., ESC-A,
etc.
