I look forward to getting home and trying this, though I am not at this point optimistic. ?Meantime, I looked, and those two drivers I had earlier installed seem to be missing, but there is a?SiLabsUSBDriver.kext in the Library/Extensions folder; nothing SiLabby in the System tree. ?shrugs. ?I will delete the one and follow your instructions, se where they lead.
The installer should put a new one in "
Library/Extensions". It doesn't always clear out the old ones.
No harm in removing everything SiLabs and doing a clean reinstall of the latest correct (for your OS version) drivers from <>..
Any opinion on those jumpers, given the specs I put in my initial Question on this topic?
Not an opinion, just the facts. There's no way your current configuration (all jumpers off and 19,200 baud) will ever work. There's a baud rate mismatch between the USB part (set by JMRI) and the onboard microprocessor (set by the jumpers).
There are only two valid setting combinations for a Power Cab:
1) All jumpers OFF and 9600 baud in JMRI.
2) All jumpers ON and 19200 baud in JMRI. (Jumper 1 is ignored so it's setting doesn't matter).
Setting (1) is the base level setting that will work with any combination of NCE USB (V6 or V7) and any Power Cab version.
Setting (2) will only work with NCE USB V7. and and Power Cab V1.65 or greater (V1.65B preferred). Enables some extra features but can be a bit more fiddly to set up.
Don't attempt setting (2) until you get setting (1) working reliably (and then only if you have the right firmware versions).
