The SPERRY UNIVAC Universal Terminal System 400 (UTS 400) is a microprocessor-based,
intelligent, general purpose display terminal for use in interactive data communica-
tions with a. central processor. The basic areas of application are:
Data entry and accessing
Control and monitoring operations
Offline operations
The UTS 400 consists of a master terminal, slave terminal, and a controller (figure
1-1). The system may be configured as a single master terminal, a master with
slaves (up to 3), or as a controller with up to 6 slaves. The system is designed to
support existing 7-bit interface devices such as the SPERRY UNIVAC Tape Cassette I
System (TCS), and 8-bit peripheral devices such as a freestanding diskette subsystem.
The system is also compatible with existing UNISCOPE display terminal software.

The master and slave terminals are designed to be placed on any flat surface (such
as a desk or table top) which affords the operator comfortable access to the console
and keyboard and provides good visibility of the display screen. Cable length
between the master ~~d slave terminals must also be considered. A minimum of 4
inches (10.2 cm) F~st be allowed to the right, left, and rear of the unit for
operation.
At lease 2 feet (61 cm) of clearance on all sides of the master and slave terminals
must be provided for maintenance; however, if the minimum clearance cannot be
provided, leave sufficient cable loop to allow the terminal to be moved to an area
with adequate work space.
Since an operator is not required for the controller, the controller may be located
in ~~ out-of-the-way place and moved (with cables attached) for maintenance access
if sufficient cable loop is provided.
At least 15 inches clearance above the controller must be provided for removal of
the top cover. A minimum of 5t inches clearance must be provided on all sides of
the controller.
*These tools are required for installation.

SECTION 2
INSTALLATION
2-1. INTRODUCTION
This section contains procedures for unpacking, installing and checking the SPERRY
UNIVAC Universal Terminal System 400 (UTS 400). The procedures are designed to
allow a Customer Engineer to install and set-up the terminal system in a minimum
amount of time.
2-2. EgUIPMENT PLACEMIlIT
The carrier is responsible for moving the equipment to its approximate location in
the prescribed area. The customer should be present while the carrier is unloading
the equipment to ensure that it is not handled roughly and that improper lifting
devices are not used.
CAUTION
Do not use a forklift to move equipment containers.
The terminal is packed in a polystrene container
which should be handled with care. The container
can be easily penetrated by forklift prongs, and
the terminal severely damaged.
The customer should instruct the carrier as to initial unit placement at the operat-
ing location. Correct placement at this time will avoid problems in unpacking
later. After the system is loaded and placed in the approximate operating location,
inspect the container or containers for signs of damage that may have occurred
during shipment.
If damage is found, or a portion of the shipment is missing, this must be noted on
the bill of lading. Also any equipment which was handled roughly or dropped during
unloading or placement should be so noted on the bill of lading, even though no
damage may be apparent. This aids in filing a claim if damage is discovered during
unpacking.

01'8 400
2-3. YNPACKING
It is recommended that two customer engineers be available for lifting the terminal
system during unpacking to avoid possible damage to the units. The procedures for
unpacking the master, slave, and the controller are contained in tables 2-1, 2-2,
and 2-3, respectively.
Information about the major electronic components of the terminal system can be
found in MP~087, SPERRY UNIVAC Universal Terminal System 400 Functional Analysis
and Servicing.
2-2
Step
NOTE
Be sure to save packing material, shipping
bags, and the two packing container halves
in the event that the system should require
shipment to a new location. The number of
sets o.r shipping material is to be deter-
mined by consultation with the customer.
The procedure for repacking the components
is provided in Section 4.
Table 2-1. Master Terminal Unpacking Procedure
Procedure
Remove master terminal container from cartun and
place on floor.
2 Cut bands holding container sections together and
remove
container top.
3 Remove bagged communication cable (if present) from
top of master terminal.
4 Remove and unpack master terminal and keyboard.
Check units for visible damage.
5 Remove tape securing power cord and front panel to
master terminal.
6 Remove exterior casework by rotating two turnlock
fastener studs at rear of unit, then sliding case-
work forward to clear the faceplate, and lifting
off.
7 Ensure that all L.E.D. indicators are securely in
place in their sockets.
8
9
Remove any internal packing material from module
cages
A1 and A5.
NOTE
Detailed inspection of printed circuit
modules, to include broken or missing
ROMs, is accomplished later in the
installation procedure.
Inventory the units and fill in the appropriate sec-
tions of the inventory and inspection report shipped
with each unit. (Use the referenced figures to assist
in inventory and inspection of the unit.) Notify
branch office of any damage or shortage.
