5.4 Hardware Description

PLCOUP006 board is a PLC coupling driver board with double branch design which only differ on the filtering stage. It has good performance in terms of transmitted channel power over a range of load impedance values complying with the FCC standard as the current carrier system.

PLCOUP006 is equipped with four test points (VDD volts, 3.3 volts, ground and PLC signal) and two orange LEDs for transmission branch indication.

Take into account that, when PLCOUP006 is set over PL360MB, VDD voltage must be 12 volts to avoid damaging the coupling board; therefore, the jumper in J16 must be set (see section Power Supply System).
