Beehive International B150 Series Operator's Manual page 4

SECTION I
INTRODUCTION
This manual provides a general equipment des-
cription and operating instruction for the Bee-
hive B100 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 terminals and a brief summary of
the differences between the B 150 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 B150 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 cur&or 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.

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 PLA 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 data to be transmitted with the
terminal's receiver input enabled for immediate
computer reply of the transmitted data [echo-
plexed] to verify proper receipt of the data) The
Input/Output and auxiliary 1/0 connectors will
interact with most standard se·rial RS232C external
devices. Data from the auxiliary port can be re-
ceived and transmitted at a baud rate separate
from that of the standard 1/0 Port. The baud
rate of the auxiliary port is strap selectable.
The CRT is a 12-incht30.5 cm (measured diagon-
ally}, digital type monitor which is formatted to
