For end of the network terminators, I build up RJ-45 connectors that have an RJ-45 connector with a 120 ohm 1/8 watt resistor between pins 4 & 5, and a second 120 ohm 1/8 watt resistor between pins 1 & 2. The reason for the resistor on pins 1 & 2 is that one of these days I may end up doing something with DMX equipment and DMX uses pins 1 & 2 for the data. The termination plug plugs into the unused connector on the last controller. For the adapter end of the network, I have a RJ-45 jack (commonly called a biscuit) at the end of the cable going out into the yard. I terminate the the data pair in the jack and then have a short patch cable to the USB adapter.
