Or, can I just configure the PCIII USB software to connect via serial port? Not getting any answers on the PC website as to the backwards compatibility of the later USB-version software.
EDIT!!! - DOH! I found it in their drop-down menu to select which version. Had to run as Admin to get it to work with Win10 Ultimate. Fingers crossed!
My understanding is that a Serial ported PCIII as preceded the USB ported PCIIIusb, needs the software of that era.
(keeping in mind that even the map file formats are different)
So, I'm very keen to hear how you make out!
Earlier this year, I got replacement PC3 software after my laptop fried.
So, it can still be had, but not by a self download from the PowerCommander website.
Instead, a PowerCommander office tech connects with your laptop, and gets the software file to your machine while remotely controlling your laptop.
They had me sorted out very quickly.
Also, the PCIIIusb software will convert a .map format map to the .djm format that the PCIIIusb uses.
The only way I found to convert .djm format maps to .map format for old Serial Port PCIIIs, was to manually build the map in .map format while using PC3 software to do so, plus also having to use it to do the map install into the PCIII unit.
