1.7 DEMO BOARD TEST SETUP
The 71M6533-DB Demo Board block diagram is shown in Figure 1-1. The configuration consists of a stand-
alone (round) meter Demo Board and an optional Debug Board. The Demo Board contains all circuits
necessary for operation as a meter, including display, calibration LEDs, and internal power supply. The optional
Debug Board, uses a separate power supply, and is optically isolated from the Demo Board. It interfaces to a
PC through a 9 pin serial port connector. For serial communication between the PC and the 71M6533, the
Debug Board needs to be plugged with its connector J3 into connector J2 of the Demo Board.
The USB-Serial Adapter allows communication between the 71M6533-DB Demo Board and a PC via its USB
port.
Connections to the external signals to be measured, i.e. scaled AC voltages and current signals derived from
shunt resistors or from current transformers, are provided on the rear side of the demo board.
Caution: It is recommended to set up the demo board with no live AC voltage
connected, and to connect live AC voltages only after the user is familiar with
the demo system.
All input signals are referenced to the V3P3A (3.3V power supply to the chip).
