SECTION I
GENERAL DESCRIPTION
This manual contains instructions and information for site preparation and installation of the DS990
Model I (DS990
/I) Intelligent Terminal System shown in figure 1-l. General descriptive
information
is provided in this section of the manual. The site preparation and installation
instructions are provided in Sections II, III and
IV of this manual under the following major
headings:
• Site preparation
• Unpacking
• Installation
The DS990/ I Intelligent Terminal System includes one DS990/ I terminal assembly and one
FD 1000 diskette drive assembly. Optional DS990/ I systems may include two FD 1000 assemblies.
Each
FD 1000 assembly has one or two FD 1000 double-sided, double-density (DSDD) diskette
drives. Therefore, a DS990/ 1 system may have from one to four
FD 1000 DSDD diskette drives.

1.2 EQUIPMENT DESCRIPTION
A rear view of the DS990/ I system is shown in figure 1-2. The terminal configuration chart located
on the rear
of the DS990/ I terminal assembly is marked to show the configuration ofthe equipment
that
is received. The terminal configuration charts for the U.S.A. and European systems are shown
in figure
1-3. Each entry on the configuration chart contains one or more blank spaces. If these
spaces are filled in or checked off, then
that particular option is installed. Where spaces are left
blank, that option
is not installed. The systems and communications equipment associated with the
different configurations are defined in tables
1-1 and 1-2. Table 1-3 describes the communications
equipment circuit cards. Table
1-4 describes the communications equipment interface cables. The
optional Model 810 printer
that is used with the DS990/ I system is shown in figure 1-4.

2.1 GENERAL
SECTION

SITE PREPARATION
Site preparation includes a detailed discussion of the power, space, environmental, special supply
and communications requirements for the DS990/ l system.
2.2 POWER REQUIREMENTS
The power requirements for each component in the DS990/ l system are given in table 2-l. These
power requirements list the load current for each voltage and frequency
that the components of the
DS990/ l system require.
CAUTION
To ensure a stable ac line voltage, do not operate heavy current
devices, such as air conditioners, fans, heaters, etc.,
on the same ac
power line with the DS990/ l system.
A suggested method of determining if the user's existing site ac input power line
is adequate for the
DS990/ l
is as follows:
l. Determine what voltage and frequency are available
at the site where the DS990/ 1system
is to be used.
2. Using the voltage and frequency determined in step l, refer to table 2-1 and calculate the
total load current the DS990/ l system requires.
3. Using standard testing techniques, load the site ac input power line to the total load
current calculated in step
2; then measure the voltage and frequency on this power line.
4. Compare the voltage and frequency measured in step 3 with the requirements listed in
table
2-1 for the FD 1000 diskette drive assembly that has the most stringent tolerances.
If the existing site ac input power line does not supply the required ac power for the DS990/ l system,
a new dedicated ac power circuit
is recommended. The user is advised to install the new dedicated ac
power circuit, when required, in accordance with the applicable national
and local electrical codes.
The site ac input power line should be available before the DS990/ l system
is received if the user
wishes to operate the system immediately.
The user should ensure
that the plug at the site ac input power line termination is compatible with the
applicable plugs provided on the components
of the DS990/ l system. Refer to table 2-1 and figures
2-1 through 2-3 for the ac power plug types provided.

2.3 SPACE REQUIREMENTS
Space requirements for the basic DS990/ l system must include ventilation, cabling, operator, and
service personnel space, in addition to space for the system components. Figures
2-4 and 2-5 show
the typical floor plan layouts
of the DS990/ 1 system with one or two FDlO00 assemblies. Table 2-1
lists the dimensions of each system component and the lengths of all associated cables. The
component dimensions and cable lengths should be used to plan the placement of the system
components
at each site. The component dimensions and cable lengths should also be used to plan
additional space for expansion
and growth of the DS990/ I system when applicable.
The basic DS990/ l system includes one FD 1000 assembly (part numbers 2267370-000I through
-0008), An optional DS990/ l system
is available with a second FD 1000 assembly (part numbers
2267370-0009
through -0016). When a second FD 1000 assembly is added to a basic DS990/ 1system,
the additional
FD 1000 assembly must be connected on the drive cable between the DS990/ l
terminal assembly
and the existing FD 1000 assembly. This equipment arrangement keeps the
FD 1000 diskette drive with the line termination at the end of the interface cable (i.e., the point most
remote from the FDlO00 controller on the interface cable).
Storage space
is also required for thermal printing paper and operating diskettes, depending on the
quantity
and size of the paper rolls and the diskette storage containers. To determine the required
storage space, refer
to table 2-2.

2.4 ENVIRONMENTAL REQUIREMENTS
The environmental requirements for the DS990/ I system, including the optional Model 810 printer,
are listed below. The components of the DS990/ I system are equipped with fans for air circulation.
Most air-conditioned sites with a reasonable amount
of room require no additional air conditioning.
If the DS990/ I system is located in a small enclosed office, verify that the ambient temperature and
relative humidity stay within the system operation range.
• System operating temperature -
l0°C (50°F) to 35°C (95°F)
• System operating humidity -
20 to 80% relative humidity without condensation
• System power dissipation -380 W without Model 810 printer, 580 with Model 810
printer
• System weight (one
FDIOO0 assembly)- 50 kg (110 lbs) without Model 810 printer, 75 kg
(165 lbs) with Model 810 printer
• System wieght (two FDIO00 assemblies) -
70 kg (155 lbs) without Model 810 printer, 95
kg (210 lbs) with Model 810 printer
• Electrostatic discharge -
To reduce the possibility of false or spurious electronic signals
caused by electrostatic discharges, it
is important to keep the relative humidity in the
equipment operating area within the system operating range. Electrostatic discharges may
also be reduced by using conductive floor mats that are grounded,
or carpets designed to
reduce the generation
of static electricity.
2.5 SPECIAL SUPPLIES
Special supplies required to operate the DS990/ 1 system are listed in table 2-2. These supplies
include:
• Thermal printing paper
• Diskettes
• Model 810 printer paper
• Model 8
IO printer ribbons
The quantity
of supplies required will depend on the size of the DS990/ I system and the amount of
system usage. It is recommended that the user have sufficient supplies on hand before the system
equipment
is received. For additional information the user should contact the nearest Texas
Instruments Incorporated Sales Office.
