1.7 DEMO BOARD TEST SETUP
Figure 1-1 shows the basic connections of the Demo Board plus Debug Board with the external equipment for
desktop testing, i.e. without live power applied. For desktop testing, both the Demo and Debug board may be
powered with just the 5VDC power supplies.

Figure 1-1: TERIDIAN D6513T3B2 Demo Board with Debug Board: Basic Connections
The D6513/T3B2 Demo Board block diagram is shown in Figure 1-2. It 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 LED, and internal power supply. The Debug Board, when using a separate
power supply, is optically isolated from the meter and interfaces to a PC through a 9 pin serial port. For serial
communication between the PC and the TERIDIAN 71M6513/71M6513H, the Debug Board needs to be
plugged with its connector J3 into connector J2 of the Demo Board.
The D6513/T3C1 Demo Board System is shown in Figure 1-3. It is almost identical to the D6513T3B2, except
that the neutral current input is added and the optional power and ground connections from the Demo Board to
the Debug Board were removed.
Connections to the external signals to be measured, i.e. scaled AC voltages and current signals derived from
shunt resistors or 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.
