1.4 BLOCK DIAGRAM
Following is a basic functional block diagram for the MC145572EVK U-Interface Transceiver Evaluation
Kit (Figure 1-2). While the board is capable of activating Òstand-alone,Ó the user may decide to use a single
ASCII terminal to gain total control of the MC145572EVKÕs activities.

1.5 GETTING STARTED
This section is provided to facilitate the userÕs introduction to the MC145572EVK. To maximize efÞciency
when working with the MC145572EVK, it is recommended that the user become familiar with the
organization of this document as well as the MC145572 U-Interface Transceiver data sheet. To identify a
starting point, power up the board and activate the U-Interface immediately. The only equipment needed
is a 5 V, 250 mA power supply, a two-wire U-Interface cable, and the MC145572EVK.
NOTE
The board shipped from the factory was thoroughly tested and veriÞed to function properly
prior to shipment. If you experience any problems or difÞculties with the operation of the
MC145572EVK, do not hesitate to call the factory or your local Motorola representative for
assistance.
1. Remove the board from its conductive environment at a static-controlled station.
2. Examine the board and its components to make certain nothing was damaged during shipment of
the board.
3. Verify that the ICs are seated properly in the socket.
