OPERATING WITH THE EVAL-BOARD
CONTROLLER
The evaluation board can be operated in a stand-alone mode
or operated in conjunction with the EVAL-BOARD CON-
TROLLER. The EVAL-BOARD CONTROLLER is avail-
able from Analog Devices under the order entry
"EVAL-BOARD CONTROLLER". When operated with
this control board, all supplies and control signals to operate
the AD7899 are provided by the EVAL-BOARD CON-
TROLLER. Software to communicate with the Control
Board and AD7899 is provided with the AD7899 evaluation
board package. This EVAL-BOARD CONTROLLER will
also operate with all Analog Devices evaluation boards which
end with the letters CB in their title.
The 96-way connector on the EVAL-AD7899CB plugs
directly into the 96-way connector on the EVAL-BOARD
CONTROLLER. The EVAL-BOARD CONTROLLER
provides all the supplies for the evaluation board. Itis
powered from a 12VAV transformer. Suitable transformers
are available from Analog Devices as an accessory under the
following part numbers:
EVAL-110VAC-US:
For use in the U.S. or Japan
EVAL-220VAC-UK:
For use in the U.K.
EVAL-220VAC-EU:
For use in Europe
These transformers are also available for other suppliers
including Digikey (U.S.) and Campbell Collins (U.K.).
Connection between the EVAL-BOARD CONTROLLER
and the serial port of a PC is via a standard Centronics printer
port cable which is provided as part the EVAL-BOARD
CONTROLLER package. Please refer to the manual which
accompanies the EVAL-BOARD CONTROLLER for more
details on the EVAL-BOARD CONTROLLER package.
