Hello,
I was trying to move my Indigo implementation over to a new server, an Xserve running on Monterey. However I am having problems getting the PowerLinc 2413U to work and am hearing the integrated FTDI Serial driver for Monterey is a DriverKit dext and it may not be compatible with the Xeon processors because DriverKit requires VT-D. While the Xserve supports VT-D, MacOS supposedly doesn't on these processors. So I was trying to try a different PLM and purchased an old PowerLinc 2412S on Ebay since these PLC's are hard to find now. I hooked it up to a USB Serial port and I am now getting Incompatible PowerLinc firmware version -- must be 8.5 or higher.
It appears to have 6.2 on it. Is there anyway to get this to work or remove the version check within Indigo to get it to work? Can these be upgraded? Surprised a firmware version would be enough on something this simple to break it. Any help would be great.
