1.
Set the
card cage power switch to
OFF (Figure 2-2).
2.
Assemble a DB-15 connector from the accessory
package to one end of a dual twisted-pair cable at
the
CPU end of the cable. Refer to
Figure 2-8 and Table 2-6.
3. Connect the DB-15 cable connector to the
RECEIVER connector J4 or
on the rear panel of
the
Refer to Figure 2-2.
4 .
Route the cables to the appropriate devices (distri-
bution line controls and/or receivers). Connect
each cable to its device.
5.
Continue routing cables from device to device until
all distribution line controls and receivers are
connected.

TIME/DATE/
TITLE (TDT) CPU
This CPU module controls the placement of
information on the monitors via four 34-pin connectors
J4). The shielded ribbon cables take titles, com-
mands, and addresses to the
master
modules the
Time/Date/Title card
cages. Refer to Figure 2-9. Video
the Matrix 44
switch banks is routed to the
card cage.
Titler modules merge titles with the video signals.
These signals are then muted to the monitors. Refer to
the V
Instruction Manual, X554.
2.4.3.1
CPU to
Master Module Cabling
The TDT CPU module
or -E)
communicates with the
TDT master
Module over a
ribbon cable. The cable
length should not exceed 10 feet.
CAUTION:
The TDT CPU must be powered
A
OFF whenever ribbon cables are connected
to or disconnected from the CPU modules.
Failure to observe this can cause damage to
the modules from static electricity.
CAUTION:
The TDT CPU communicates with
A
the TDT card cage over a shielded parallel
cable to meet FCC
regulations. To
avoid damaging circuits, make sure that the
cable connectors are inserted properly.
Refer to Figure 2-9.
1.
Set the
card cage power switch to
(Figure 2-2).
2. Identify the appropriate panel connector on the
CPU card cage (Figure 2-9). The
connectors are labeled J4. Refer
2-7
for connectors and corresponding monitor
addresses.
CAUTION:
DO NOT FORCE THE CABLE
CONNECTOR ONTO THE PANEL
CONNECTOR!
Forcing the connectors to-
gether can cause a connector spring to fly
loose. Instead, tighten the thumbscrew a
few
turns
then press the cable connector
partly onto the panel connector. Alternate
between tightening the thumbscrew and mat-
ing the connectors until the cable connector
seats completely
on
the panel connector.

5.
Plug the mating
connector on one end of a
34-conductor ribbon cable into the appropriate
connector (Jl-J4) on the
CPU. Refer
to Figure 2-9.
Route the ribbon cable to the
master module. Make sure there are no sharp
bends in the cable.
Set the
power switch to OFF. The
power switch is mounted on the rear panel of the
TDT card cage.
