QUICK START GUIDE
To begin using the
EVAL-AD7761FMCZ
evaluation board, take
the following steps:
1.
Ensure that the
EVAL-SDP-CH1Z
board is disconnected
from the USB port of the PC. Install the evaluation board
software from the CD included in the evaluation board kit.
Restart the PC after the software installation is complete.
(For complete software installation instructions, see the
Software Installation Procedures section.)
2.
Connect the
EVAL-SDP-CH1Z
board to the
EVAL-
AD7761FMCZ
evaluation board (unpowered). Figure 1
illustrates the connection: J4 of the
EVAL-SDP-CH1Z
board adapts to the receiving socket on the
EVAL-
AD7761FMCZ
printed circuit board (PCB).
3.
Ensure that the boards are connected firmly together.
4.
Apply power to the
EVAL-AD7761FMCZ
evaluation board
via the supplied 9 V dc adapter at J1 (LK1 in Position B).
Alternatively, supply an external voltage in the range of 7 V
to 9 V from a bench top power supply using the J3 connector
(LK1 in Position A).
5.
Connect the 12 V dc supply to the
EVAL-SDP-CH1Z
board, and then connect to the PC using the supplied USB
cable. For Windows® XP, the PC may need to search for the
