2-2 INSTALLATION PROCEDURE
2-2. I Receipt and Unpacking of Equipment
The Display Terminal is shipped completely as sembled and ready for
operation.
The display terminal interface connection is provided by an
(1/0)
input
I
output cable which must either be fabricated locally or ordered from
the Raytheon Company.
This cable is used to couple data and control signals
between the Display Terminal and the connected device.
Upon receipt of the Display Terminal, unpack the shipping crates as
follows:
a.
Carefully open the shipping crate(s) and check the contents against
the shipping list to verify the arrival of all ordered equipment (such
as spare parts, cables).
b.
Remove the Display Terminal from its shipping crate and place it on
a convenient work bench or table.
c.
Carefully examine the exterior of the Display Terminal for any
damage which may have occurred during shipment.
Report any
damage noted immediately.
2-2.2 Cable Requirements
The
110
cable used for connecting the Display Terminal to the interfacing
device can be any good quality shielded 4-twisted pair cable and an MS-3106AI45-
55 connector.
The maximum allowable length between the Display Terminal and
the connected interface device is 50 feet.
2-2.3 Cable Fabrication
If specifically requested, a cable precut to customer requirements is sup-'
plied with the Display Terminal.
If the cable is not ordered, it may be locally
fabricated using the cable and connectors described in the preceding paragraph.
When planning the installation, make sure that the cable length does not exceed
the maximum limit of 50 feet.
Use standard cable assembly techniques to fabri-
cate the cable, taking care when soldering each connection to prevent shorts be-
tween connector pins.
Raytheon Drawing No. 425116 (Chapter 7) illustrates dis-
play terminal signal connections to and from the connected interface device.
