Rs485 is in its design a different interface from rs232. There are multiple pinouts for rj45 connectors including straight through (t568a or t568b), crossover, rolled, t1, and loopback. Ideally the two ends of the cable will have a termination resistor connected across the two wires and two powered resistors to bias the lines apart. Figure 3 is an rs485 wiring diagram for rs485 pinout db9 connectors. Received waveforms are shown for examples of proper and improper cable termination.
Remember, each connection needs one of each. A pinout is a specific arrangement of wires that dictate how the connector is terminated. Please see product page, cart, and checkout for actual ship speed. Average Time to Ship 1-3 Days, extra ship charges may apply. The normal way to implement this is with a two wire system with differential signal levels. More Products From Fully Authorized Partners.
