Installing the AIEB1 I/O Expansion Board
The optional AIEB1 Input/Output expansion board adds digital I/O (both optical and
coaxial formats) and six assignable outputs to the A3000. For information about the
board’s connectors and general board setup, refer to information elsewhere in this manual
(☞22 to 26).
Important
Before performing the installation, please read precautions “Handling and Installation
of Options,” found at the beginning of this manual.
Procedure
1.
Be sure that you have the following at hand before starting the installation.
• A3000 main unit
• AIEB1 I/O expansion board
Confirm that there are 3 cables extending from the board.
• Phillips screwdriver
Magnetic-tipped screwdriver is recommended.
• Workbench
Please carry out all work on a stable workbench or table. Spreading a cloth over the
work surface will help prevent scratching.
• Gloves: Be sure to wear gloves so that your hands are not scratched by the metal
cover or other metal parts.
2.
Switch off the A3000 power, and unplug the power cord from the wall outlet.
3.
Remove the screws holding the A3000 top cover in place.
Set the A3000 upside down on the workbench and unscrew the 6 screws along the sides
of the bottom (see drawing). Then turn the A3000 right side up again and unscrew the 3
screws along the top. Then unscrew the 5 screws holding the cover to the rear panel.
