 The red, green and brown wire coming out of the USB to RS485 cable are not used.
+== Note on bus termination ==
+RS485 networks are traditionally terminated at both ends with 120Ω terminators. This is not required if the cable length is short, but may be required for longer cable runs. The ET340 meter has a built in termination resistor that can be enabled by bridging terminals 7 and 9.
