EVAL-AD2S1200/05SDZ BASIC HARDWARE SETUP
The E VA L -AD2S1200/05SDZ board connects to the EVA L -
SDP-CB1Z system demonstration platform board. The
EVA L-SDP-CB1Z board is the controller board, which is the
communication link between the PC and the main evaluation
board. Figure 2 shows a photograph of the connections made
between the EVA L -AD2S1200/05SDZ daughter board and the
EVA L-SDP-CB1Z board.
A resolver or resolver simulator should be connected to the
EVA L-AD2S1200/05SDZ board as outlined in Table 6. The
primary windings, R1 and R2, are connected to the buffered
excitation ouputs from the evaluation board. The resolver
stator outputs should be connected to the corresponding
EVA L-AD2S1200/05SDZ board inputs.

The gain stage for the excitation buffer can be controlled via
Link LK7 and Link LK8. These should be configured to provide
the necessary gain to allow the resolver inputs to lie within the
required specification. See Table 2 for the link options.
Before connecting power, connect the EVA L -AD2S1200/05SDZ
board to Connector A on the EVAL -SDP-CB1Z board. Nylon
screws are included in the E VA L -AD2S1200/05SDZ kit and can
be used to ensure that the EVA L -AD2S1200/05SDZ and EVA L-
SDP-CB1Z boards are connected firmly together.
After the EVAL -AD2S1200/05SDZ board and the EVA L -SDP-
CB1Z board are connected securely, connect the power to the
EVA L-AD2S1200/05SDZ board. The EVA L-AD2S1200/05SDZ
board requires an external power supply adapter, which is
included in the evaluation board kit. Connect this power supply
to Connector J702 on the EVA L -AD2S1200/05SDZ board. For
further details on the required power supply connections and
options, see the Power Supplies section.
Before connecting the E VA L -SDP-CB1Z board to your PC,
ensure that the E VA L -AD2S1200/05SDZ software has been
installed from the enclosed CD. The full software installation
procedure is detailed in the Evaluation Board Software section.
Finally, connect the EVA L-SDP-CB1Z board to the PC via the
USB cable enclosed in the EVA L -SDP-CB1Z kit. If using a
Windows XP platform, you may need to search for the E VA L -
SDP-CB1Z drivers. Choose to automatically search for the
drivers for the EVAL -SDP-CB1Z board if prompted by the
operating system.
