DBS 16 USER'S MANUAL
SECTION 1
DBS 16 SYSTEM OVERVIEW
1.1 IITBODOCTIO.
Section 1 is a detailed overview of the DBS 16 ,,syst.em. It
describes the basic physical characteristics, functional aspects,
and additional capabilities of the system, and also oqtlines the
applicable operating systems (software) that c.ontrol all DES 16
operations. -,' ": " ,~.~
1.2 SISTEK DESCRIPrIOI
The DBS 16 is a 16-bit, multi-user, mUlti~ta~king~ mUlt:i~pro.6e'~sor
microcomputer system. The two basic components of'tbe :b~'s 16
system are:
1. AVideo Display Terminal with keyboard
2. The Desktop Unit
The Desktop
Un! t houses the system electronics and two disk
drives.
An optional third component is the Expansion Box. The Expansion
Box can be added to your basic system when you need to install
five or more display terminals, or if yo~ want to install multibus
boards for advanced computer performance. When in use, the
Expansion Box is connected to the Desktop Unit to form the stack
(see Figure 1-1).
The Intel 80186 microprocessor used in the DBS 16 enables 16-bit
operation. The Desktop Unit and Expansion Box can be used for
single-user and multi-user operations. An operating system makes
the DBS 16 system multi-tasking, allowing you to perform several
operations concurrently at one terminal. The number of operations
that can be performed depends on the amount of memory available
for the operation. The Expansion Box, when installed to form the
Stack, makes the DBS 16 amul ti-processor system, because it
allows for additional microprocessors.

You have a choice of any of three system configurations, to easily
conform the DBS 16 to your business needs.
Iou can start with the Single-User system configuration, and when
more terminals are needed, expand to the Multi-User system. When
more users and increased processing speed are needed, you can
easily expand the configuration to the Multi-Processor Stack
system.
The advanced technology and performance capability of the DBS 16
are clearly represented in eaoh system configuration. This, as
well as the versatility of the system, becomes more evident as you
expand
the. system from one configuration to another.

DBS 16 USER'S MANUAL
DBS 16 SYSTEM OVERVIEW
1.2.1 The Single-User S7ste.
The two basic DBS 16 components are used in the Single-User system
configuration. Only one display terminal can be connected to the
Desktop Unit (see Figure 1-2). Either of two operating systems,
CP/M-86 or MS-DOS, can be used in single-user operation. Refer to
the PBS 16 CP/M-56 System Reference Manual and the PBS 16 MS-POS
System Reference Manual for detailed information on each. .

DBS 16 SYSTEM OVERVIEW
1.2.2 The Mu1ti-User Systea
The basic DBS 16 components are also used in the Multi-User system
configuration. This configuration allows you to connect up to
four display terminals to the Desktop Unit (see Figure 1-3). The
MP/M-86 operating system is required when operating more than one
display terminal. The operating system allows for multiple
terminals to be added in this expanded system. Although MP/M-86
is required for mul ti-user operation, it can still be used in
single-user operation. Refer to the PBS 16 MP/M-86 and DBS-Net
Systems Reference Manual for detailed information.

1.2.3 The Hulti-Proceaaor Stack Syste.
The Expansion Box is used with the basic DBS 16 components in the
Multi-Processor Stack system configuration. In this setup, the
Desktop Unit can no longer be used for connecting display
terminals. Those terminals must be connected to the Expansion
Box. This configuration allows you to connect a maximum 16
terminals (see Figure 1-4). The Expansion Box contains six
multibus card slots. Any of the six slots can be reserved for
DBSI Slave CPU boards or mul tibus boards. Iou can connect from
one
to four display terminals to each Slave CPU board for a total
of up to 16 terminals in the system.

DBS 16 SYSTEM OVERVIEW
The ~~/~r86 and DBS=Net operatir~ systems are required to operate
in the Multi-Processor Stack system configuration. This is the
same MP/M-86 operating system used in the Multi-User system.
However, it must be run concurrently with DBS-Net. Refer to the
PBS 16 MP/M-86 and PBS-Net Systems Reference Manual for detailed
information on both operating systems.
1.3 DBS 16 COIIPORaT DESCBIPTIOBS
The following paragraphs describe the physical aspects of all the
DBS 16 system components.
1.3.1 The Video Displa~ Tera1Da1
The Video Display Terminal basically consists of a CRT screen and
typewri ter-style keyboard with alphanumeric keys. Refer to the
Terminal Guide in Appendix B at the back of this manual for a
detailed description of the DS 81 Video Display Terminal. Consult
your computer dealer if you will be using a different model
display terminal.
1.3.2 The Desktop Unit
The Desktop Unit (part of the Stack) is available in two disk
drive models: either two floppy drives, or one Winchester
drive/one floppy. Also contained within this unit are the Master

DBS 16 USER'S MANU AL
DBS 16 SYSTEM OVERVIEW
1.11 OPBIArDG SIsrBII SOFTVUE
An operating system is composed of agroup of correlative computer
programs,
commonly referred to as software, that control system
opera tions. These programs enable the user to perform certain
operations on the system (i. e., read, create, edit, and delete
files) •
There
are four operating systems that run on the DBS 16. Each is
contained on a diskette. They are as tollows:
1. CP/M-86
2. MS-DOS
3. MP/M-86
4. MP/M-86 and DB8-Net
There is a special configuration program that each operating
system automatically executes the first time that you power-up the
system. This program makes the operating system compatible with
the type of system you are using.
CP/M-86 and MP/M-86 were originally designed by Digital Research.
DBSI has enhanced them to run on the DBS 16.
MS-DOS was originally designed by Microsoft Inc. It too has been
enhanced
by DBSI to run on the DBS 16.
DB8-Net was designed by DBSI to run concurrently with MP /M-86 on
the DBS 16, when DBSI Slave CPU boards are used.
CP/M-86 is the standard operating system provided with the DBS 16.
You can obtain any of the other operating systems (in addition to
CP/M-56) from your computer dealer. Refer to the specific DBS 16
System Reference manual for a detailed description of the
operating system you are using.

Find a stand, table or desk for the display terminal(s). If
desired, place the Desktop Unit and the Expansion Box
(optional) on the floor.
2. Clean EnviroDllent?
Make sure the area is clear of any of the following items, to
ensure adequate ventilation for the system, and to prevent
accidental spillage or damage to the system.

3. Buaidity?
Heavy dust
smoke
Food
Drink
Foreign objects (e.g., staples, paper clips)
The humidi ty level should be wi thin the acceptable range of
20% to 90%.

•
Too much humidity interferes with system
operation.
Too little humidity creates static, which also
interferes with system operation.
Talk with your computer dealer to determine the
acceptable humidity level for the area in which
your system will be installed.
_. Interrerence?
Make sure the system is at least 15 feet from any of the
following sources of interference:
•
•
Strong radio frequency
Magnetic fields; e.g., an office copier, a magnetic
paper clip dispenser, or eqUipment with large motors

DBS 16 USER'S MANU AL
INSTALLATION
After finding the best location for the DBS 16, you'll want to
decide on a convenient physical arrangement for your system. For
instance, in an office environment the display terminal could be
placed on a table or desk, with the Desktop Unit set to the left
or right side of the display terminal (see Figure 2-1). There is
no required arrangement for these two components of the DBS 16.
If the display terminal must be si tuated farther than 250 feet
from the Desktop Uni t or Expansion Box, you may need a modem
eliminator or serial communication line driver.
As previously stated, the humidity level should be maintained
within an acceptable range. Although the DBS 16 operates
satisfactorily at lower humidity levels, static (i.e., from
walking over the carpet) can cause interference when you touch the
system. Precautionary measures, such as placing anti-static mats
under
each operator's table and chair, can reduce or eliminate
this type of interference.
When you have finished setting up your system, set the appropriate
line vol tage wi th the correct fuse for your locale by using the
Line Voltage Setting Chart in the following paragraph.

DBS 16 USER'S MANUAL
INSTALLATION
2.3.2 Setting the Line Voltage
The DBS 16 requires a steady supply of 115 Vac, 60 Hertz
(domestic)
at 1.5 Amps or 230 Vac, 50 Hertz (international) at
0.75 Amps. Incorrect or fluctuating line voltages can cause disk
read or write errors and damage to the components. If you have
any doubts about
the line voltages at your location, contact your
computer
dealer before proceeding with the installation.
The two-position line voltage select switches at the rear of the
Desktop Unit (see Figure 2-3), and at the rear of the Expansion
Box (see Figure 2-4) are used for setting the line voltage for the
entire DBS 16 system. Note that both line voltage .switches must
be
in the same position to receive the appropriate line voltage.
