+ | |||
+ | RS485 networks are traditionally terminated at both ends with 120Ω terminators. This is not required if the cable length is short and you are using the Victron supplied RS485 to USB lengths, but may be required if they are extended for longer cable runs. The ET340 meter has a built in termination resistor that can be enabled by bridging terminals 7 and 9. | ||
