lesmar96 Posted November 11, 2019 Report Share Posted November 11, 2019 Hello, Just checking in what USB to serial converters you would recommend for connecting to Jazz. I have 2 Jazz processors here and I am unable to communicate with either of them. They are older models and only support serial via MJ20-PRG. I am using Unitronics serial cable p/n: MJ10-22-CS25. I get no errors in Device Manager when I plug in the USB-to-serial converter. It grabs Port 3. But if I set U90 ladder to Port 3, the communication still times out. I have several USB-to-Serial adapters that I have tried........I have several that are PL2303, but they all show up as "PHASED OUT SINCE 2012, PLEASE CONTACT YOUR SUPPLIER". The one I am using is a FTDI. Could that be making the difference? I believe I have read or heard that Unitronics doesn't like the FTDI even if the driver is installed and the device is working properly. If so, I need to work at getting updated USB-Serial converters. Please advise.........any good USB-serial converters that you recommend?
