Hello,

We see that the RevPi Flat has two RS-485 inputs, yet only one of them supports direct field wiring. The other one appears to accept only an RJ12 connection? This adds a lot of complexity for us. How do we convert bare comms wires from our field devices into an RJ12 connection? Do you have an adapter?

Hi jdalbora,

the RJ12 interface is ment to directly connect certain devices without having to wire anything. In order to use it with direct field wiring you can use a terminal block and a rj12 wire where you strip one end and attach it to the terminal block. The pinout is as following:

Code: Select all

1: NC  (Not connected)
2: GND (Ground)
3: N   (Negative)
4: P   (Positive)
5: GND (Ground)
6: NC  (Not connected)
