When cabling over long distance, you have to take care of the twisted pairs. This means that along with the above cabling conventions, the emission (TX+/TX-) and reception (RX+/RX-) signals have to be connected on the same twisted pair:

TX+: pin3, TX-: pin6

Twisted pair 1

 

 

RX+: pin1, RX-: pin2

Twisted pair 2

 

 

Pins 4, 5, 7 and 8 do not have to be connected. The following picture shows the twisted pair connections:

If the eWON® is connected to a hub, it has to be connected like any other device, with a straight cable. Again, the wiring is as shown on the following picture, and care should be taken to keep the RX and TX signals on twisted pairs:
