5. Hardware Installation
Important: Switch off the computer and remove the power cable from the power supply be-
fore fitting the AEB.
1. Disconnect the power cable and all other cables from the computer.
2. Remove the PC housing; further information on how to do this can be obtained from your
computer´s instruction manual.
3. Neutralize the static build up by touching the PC metal-chassis before unpacking the AEB
from the protective bag.
4. Connect AEB and PCI-card using the supplied 3-wire cable. Plug one end into the connector
ST7
on the PCI-card, the other end into
ST7A
on the AEB.
5. Connect the AEB's
DIG OUT
and the PCI-card's
CD-IN/Sync-In
using the supplied 2-wire
cable. Watch out for correct polarity: The shield wire is black, and must be connected to the
pin marked
GND
on the PCI-card (the right one).
6. Connect power supply: The AEB uses a floppy power connector (3,5"). In case no such con-
nector is available use the supplied adapter cable to connect the AEB to any free 5 ¼" power
connector.
7. Insert the AEB into a free slot, press and fasten the screw. The AEB needs no slot on the
motherboard, but includes a stabilizing edge, which fits in both PCI and ISA slots.
8. Re-insert the PCI-card in a PCI slot and fasten the screw.
9. Re-place the PC housing and tighten the screws.
10. Re-connect the power cable and all other cables/connections.
