RJ45 8-pin (2-Wire)
If an 8-pin Rj45 connector is being used the pins will shift one position:
| Pin | Position |
|---|---|
| Pin 1 | – (minus) signal |
| Pin 2 | N/A |
| Pin 3 | GND |
| Pin 4 | + (plus)signal |
| Pin 5 | Other+ (plus) signal |
| Pin 6 | SGND |
| Pin 7 | Not used |
| Pin 8 | Not used |
You may also need to enable the 4th switch of the DIP switch (up position) to enable termination for the RS-485 line.
Set termination as necessary. The always keep transmitter enabled setting should be enabled if you are using an external 4-wire to 2-wire converter.
