The default configuration of the PLC line coupling targets the G3-PLC (ITU G.9903) and PRIME (ITU G.9904) CENELEC A-band protocol standards. With a few BOM modifications, the STCOMET development kit can be adjusted to fit other narrow-band PLC protocols in CENELEC A-band or FCC band (e. g.: S-FSK IEC61334-5-1, IEEE 1901.2, G3-PLC FCC, METERS AND MORE).
