Installing a DTIC Card
The procedure to install a DTIC is as follows:
.
For a new installation, configure the SLOTS Table for the DTIC card before the card is installed.
1. Put on antistatic wrist strap. Connect it to an unpainted portion of the cabinet.
For a first-time installation, the DTIC–E1 kit must be installed. Follow steps 2 and 3, then follow the
steps for either a 75-ohm or 120–ohm DTIC-E1 adapter installation. If this is not a new installation,
go to step 5.
2. Remove two jack screws and washers securing the connector marked J2 (for the Octel Overture 200)
or J4 (for the Octel Overture 300) to the I/O panel on the back of the system. Refer to Figure 9-11 for
the Octel Overture 200 or Figure 9-12 for the Octel Overture 300.
3. Using two new jack screws provided with the kit and washers just removed, attach the grounding
strip where shown in Figure 9-11 for the Octel Overture 200 or Figure 9-12 for the Octel Overture
300.

Connect the 75-ohm DTIC–E1 adapter, to the amphenol connector on the I/O panel
corresponding to the DTIC card slot in the system card cage. Secure the velcro strap. Make sure
that the adapter is completely seated.
Secure the grounding screw on the top of the adapter to the grounding strip.
Attach the customer-provided 75-ohm transmit and receive coax cables to the appropriate coax
connectors on the adapter where shown in Figure 9-13. Go to step 5.
Prepare the customer-provided I/O cable as follows:
Cut the cable jacket so that the conductors protrude approximately 25mm (1 inch) from the
-
end of the jacket.
Strip approximately 6mm (.25 inch) of insulation from the end of each conductor.
-
Cut the shield so that a 13 mm (.5 inch) length of shield foil or braid can be pulled back
-
over the cable jacket.
To pass regulatory requirmenets, shielded cable must be used.
Connect the conductors from the I/O cable to teh 120-ohm adapter s shown in Figure 9-14.
Secure the jacket of the cable to the adapter using the clamp provided or remove the clamp and
secure with a tie-wrap through 2 small rectangular cutouts. Make sure the clamp or tie wrap
clamp-down around the shield that has been folded back around the cable jacket.
Connect the adapter to the amphenol connector on the I/O pannel corresponding to the DTIC-E1
card slot in the system card cage. Secure the velcro strap. Make sure the adapter is completely
seated.
Secure the gorunding screw on the top of the adapter to the grounding strip. Go to step 5.
