Installing I/O Cards
Attention: For technical reasons, certain card combinations are not supported.
Before installing any cards, check the Yamaha web site (see page 6) to see
whether your card is compatible.

Also check the total number of cards that can be installed in the unit. Installing cards that are
not endorsed by Yamaha may cause electrical shock, fire, or damage to the unit.
This section explains how to install I/O Cards.
1 Turn off the DM2000.
Undo the two fixing screws and remove the slot cover, as shown below.
2
Keep the cover and fixing screws in a safe place for future use.
3 Insert the card between the guide rails and slide it all the way into the slot,
as shown below. You may have to push firmly to plug the card into the inter-
nal connector.
4 Secure the card using the attached thumbscrews. Do not leave them loose,
as the card will not be grounded correctly, which may cause the DM2000 to
malfunction.
You can check which I/O Cards are installed on the Word Clock Select page (see page 51).
