Wayne CAT was 485. Wayne chose a TCP/IP to 485 converter for EMV to keep it simple.
You are converting a TCP/IP connection to RS-485 and sending it over 2 conductors between 2 devices.
Whatever protocol those conductors originally may have carried is irrelevant, they have been repurposed.
That said, RS-485 is pretty good at being electrically noisy and coupling that noise into adjacent conductors. The lower level of Gilbarco 20mA pump loop is going to make it more susceptible to induced noise than the Wayne 45mA current loop would be. If you use Wayne Connect with Gilbarco and CRIND and pump loops are sharing a conduit then it is quite possible that repurposing that CRIND loop to RS-485 may induce noise on the pump loop and cause random and intermittent pump communication issues.

Re: Wayne Connect with Gilbarco
Dover called it that because you took 485 communication off the catix and ran it through that box. You no longer use it for 485. There is no 485 connection on either end of the boxes. They didn’t market if “for any EMV conversion” because this box was used for media at the pump long before emv.
See bigbadjohns post. Rs232 vs 485 does not matter. Two wires go directly from the in store Wayne connect to the in dispenser Wayne connect unit. From there you would have an Ethernet cable go from the in store unit to your MNSP. The other end you would have an Ethernet cable from the in dispenser unit to wherever it would plug in on gilbarco.
While it may cause more noise. I wouldn’t think it would be anywhere near enough to cause issues on the pump side especially if they are using twisted pair.
It’s ok if you say you don’t know….

Re: Wayne Connect with Gilbarco
You're still suggesting that in order to perform conversion of 485 to IP, the device handling that frequency modulation is entirely capable of being swapped out for the purposes of modulating a 232 signal - with no additional changes elsewhere in the chain. This is fundamentally incorrect. But again, very open to anyone proving me wrong here with a working site.
