Are terminating resistors required on my RS-485 network? |

Not generally, and most of the time they generate more problems on the network. Our recommendation is to setup your RS-485 network without terminating resistors initially. If communication problems are seen which can be attributed to signal echoes or reflections, then a 120 OHM terminating resistor may be required on the RS-485 line. |

I have a device that expects power to be provided through a serial or Ethernet connection. Do ProSoft communciations solutions provide such power?
