1 GETTING STARTED
1.1 GENERAL
The TERIDIAN Semiconductor Corporation (TSC) 71M6513/71M6513H Demo Board is a demonstration board
for evaluating the 71M6513/71M6513H device for 3-phase electronic power metering applications. It in-
corporates a 71M6513 or 71M6513H integrated circuit, peripheral circuitry such as a serial EEPROM, emulator
port, and on board power supply as well as a companion Debug Board that allows a connection to a PC through
a RS232 port. The demo board allows the evaluation of the 71M6513 or 71M6513H energy meter chip for
measurement accuracy and overall system use.
The board is pre-programmed with a Demo Program (file name 6513_demo.hex) in the FLASH memory of the
71M6513/6513H IC. This embedded application is developed to exercise all low-level function calls to directly
manage the peripherals, flash programming, and CPU (clock, timing, power savings, etc.).
The 71M6513/6513H IC on the Demo Board is pre-programmed with default calibration factors.
1.2 SAFETY AND ESD NOTES
Connecting live voltages to the demo board system will result in potentially hazardous voltages on the demo
board.
BEFORE OPERATING THE DEMO BOARD, THE JUMPERS ON JP2 AND JP3 (IF IN-
STALLED) SHOULD BE REMOVED! IT IS RECOMMENDED TO OPERATE THE
DEBUG BOARD WITH ITS OWN POWER SUPPLY.
THE DEMO SYSTEM IS ESD SENSITIVE! ESD PRECAUTIONS SHOULD BE TAKEN
WHEN HANDLING THE DEMO BOARD!
EXTREME CAUTION SHOULD BE TAKEN WHEN HANDLING THE DEMO BOARD
ONCE IT IS CONNECTED TO LIVE VOLTAGES!

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.

1.7.1 POWER SUPPLY SETUP
There are several choices for meter power supply:
• Internal (using phase A of the AC line voltage). The internal power supply is only suitable when phase A
exceeds 220V RMS.
• External 5VDC connector (J1) on the Demo Board
• External 5VDC connector (J1) on the Debug Board.
The three power supply jumpers, JP1, JP2, and JP3 (JP2/JP3 is only provided on the D6513T3B2
Demo Board), must be consistent with the power supply choice. JP1 connects the AC line voltage to
the internal power supply. This jumper should usually be left in place. JP2 and JP3 should be left
open (unconnected).
1.7.2 CABLE FOR SERIAL CONNECTION (DEBUG BOARD)
For connection of the DB9 serial port to a PC, either a straight or a so-called “null-modem” cable may be used.
JP1 and JP2 are plugged in for the straight cable, and JP3/JP4 are empty. The jumper configuration is reversed
for the null-modem cable, as shown in Table 1-1.
Jumpers on Debug Board
Cable
Configuration Mode JP1 JP2 JP3 JP4
Straight Cable Default Installed Installed -- --
Null-Modem Cable Alternative -- -- Installed Installed
Table 1-1: Jumper settings on Debug Board
JP1 through JP4 can also be used to alter the connection when the PC is not configured as a DCE device.
Table 1-2 shows the connections necessary for the straight DB9 cable and the pin definitions.

1.8 USING THE DEMO BOARD
The 71M6513/6513H Demo Board is a ready-to-use meter prepared for use with an external current trans-
former.
Using the Demo Board involves communicating with the Demo Code via the command line interface (CLI). The
CLI allows all sorts of manipulations to the metering parameters, access to the EEPROM, initiation of auto-cal
sequences, selection of the displayed parameters, changing calibration factors and many more operations.
Before evaluating the 71M6513/6513H on the Demo Board, users should get familiar with the commands and
responses of the CLI. A complete description of the CLI is provided in section 1.8.1.

Commands for CE Data Access:
] CE DATA ACCESS
Description: Allows user to read from and write to CE data space.
Usage: ] [Starting CE Data Address] [option]…[option]
Command
combinations:
]A??? Read consecutive 16-bit words in Decimal, starting at
address A
]A$$$ Read consecutive 16-bit words in Hex, starting at address A
]A=n=n Write consecutive memory values, starting at address A
]U Update default version of CE Data in flash memory
Example: ]40$$$ Reads CE data words 0x40, 0x41 and 0x42.
]7E=12345678=9876ABCD Writes two words starting @ 0x7E
CE data space is the address range for the CE DRAM (0x1000 to 0x13FF). All CE data words are in 4-byte (32-
bit) format. The offset of 0x1000 does not have to be entered when using the ] command, thus typing ]A? will
access the 32-bit word located at the byte address 0x1000 + 4 * A = 0x1028.
