Installing a DTIC Card

The

procedure to install a DTIC is as follows:



For a new installation, configure the SLOTS T

able for the DTIC card before the card is installed.

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.

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 9-1

1 for

the Octel Overture 200 or Figure 9-12 for the Octel Overture 300.

Using two new jack screws provided with the kit and washers just removed, attach the grounding

strip where shown in Figure 9-1

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.

For 120-ohm DTIC-E1 installations:

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.

 T

o 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.

Check that the DTIC’s SW1 adn SW2 switches at the bottom right-hand corner of the card are set to

the correct positions; 75-ohm or 120-ohm. these switches and their settings are marked on the card.

While holding top and bottom edges of the card, slide the DTIC into the card cage.
