192 I/O Guide30
Hardware Setup Changes
After Adding a Card
The additional inputs and/or outputs provided
by the new card will appear in the Hardware
Setup dialog, with the same controls and param-
eters as for the original card of the same type.
For example, if you add an Analog Input card to
the original three cards, a second Analog Input
tab will appear in the Hardware Setup dialog.
You can route these new inputs (which will in
this case be called Analog Inputs 9–16) with the
same controls and parameters as the factory-in-
stalled version of the card.
Troubleshooting
If the power ring does not turn from orange to
green when you boot the computer, make sure
you reconnected the DigiLink cable to the Pri-
mary port on the rear of the unit. If the DigiLink
cable is securely fastened and the other end is
plugged into an HD Core or Process card in a
computer that is booted, you may have inad-
vertently disconnected another 50-pin cable
when installing the card.
Removing an I/O Card
In the event of a problem with one of the cards
in your 192 I/O, you can remove the card and
send it to Digidesign for repair.
The modular nature of the HD system allows
you to simply return the specific card, instead of
the entire 192 I/O. Your HD system will con-
tinue to function while missing a single card. It
will not function if more than one of the fac-
tory-installed cards is removed, or if the wrong
card is in any of the first three bays.
To remove an I/O card from the 192 I/O:
1 Power off and disconnect the 192 I/O from
your HD system.
2 Make sure that the equipment is properly
grounded.
3 Remove the top cover of the 192 I/O by ex-
tracting the 16 small Phillips-head screws
around the edges of the top cover, and lift it off.
Put the screws in a safe place.
4 Remove the five screws on the front plate of
the card to be removed.
5 Gently pull the 50-pin connector off of the
edge of the card.
Whenever a card is added or removed from
an HD I/O, the routing in the Hardware
Setup dialog will revert to default assign-
ments. If you have complex routing and or
mirroring in place, please note the assign-
ments and reassign the inputs and outputs
after the new card has been properly identi-
fied.
Before handling any of the cards or internal
components of 192 I/O, discharge any static
electricity by touching the outer casing of the
power supply.
