71M6513/71M6513H Demo Board User’s Manual
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.

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.
