Please, I need information about this integration. Here in Brazil, we know that in the USA, the NEC approved with Micros, but I doubt if we will use RS232 (DB9 side OPERA with N24) serial or IP (RJ45 side OPERA with FIAS) interface.

- Integration - UM8000 x OPERA (not ok)

To convert RS-232 to IP, you can use this:
