I’ve been a group member for quite some time, but very inactive for almost as long…at least a decade. I was installing some decoders the other day and ran into some hiccups and realized it was time to connect JMRI/Decoder Pro to my test track (layout under construction). I was planning to use my old iMac (from 2011 running OS 10.13.6) but it wouldn’t start up…so I just got a newer iMac just for the layout - 24” M1 from 2021.

I just installed OS 15.4.1, DP 5.10. and Java from Azul (zulu11.80.21…dmg). My test track uses a DCS50 (Zephyr) and ?Soundtraxx PTB-100 (booster). I’ve also got the test track wired so that it is either the main or programming track (DPDT switch to select the output from the Zephyr). The Serial interface is a LocoBuffer-USB (v2.03).

Alex,

Don't use screenshots for the System Console. ?Use the "Copy to clipboard" button and paste the text. ?Text is much easier to read.

The selected device is not correct for the LocoBuffer-USB.

You need to install the driver from?.?

Make sure that you select the ARM DMG download. ?

If you still have issues, follow the instructions at?

I don't have mail set up on that computer (running JMRI) so it was easiest to take a screen shot to transfer it to my main computer.

?

As for the driver, I thought that might be an issue and went to RR-Circuits and downloaded that file. When I tried to install it I received an error that the file was not in the expected place (wanted to be in the Applications folder, but said it was somewhere else). And didn't appear to install.

I just bought a new MacMini M4 and did not have to install any drivers. Why don’t you unplug the USB loconet connection and in terminal, ls -l /dev/cu* to list and save that to compare against the list after plugging back in. Just select that in JMRI and you should be fine.

?

Why don't I? ...because I don't know what that is or what it does?

?

When I type "ls -l /dev/cu*" in terminal it returns this:

crw-rw-rw-? 1 root? wheel? 0x9000005 May? 7 06:47 /dev/cu.Bluetooth-Incoming-Port

crw-rw-rw-? 1 root? wheel? 0x9000001 May? 7 06:59 /dev/cu.debug-console

crw-rw-rw-? 1 root? wheel? 0x9000003 May? 7 06:51 /dev/cu.wlan-debug

?

That's half of the 6 options available in DP.?

?

When I plug the LB-USB back in the same three show in the list.

?

I've tried all three and still get the timeout error message...

Try ls -l /dev/ttyA* or ls -l /dev/tty* and look for the device. I’m out of suggestions.

As a follow-up, I downloaded the driver file from your source (not RR-Circuits) and tried installing (installer in the Applications Folder). On the first attempt, despite allowing the permissions, the driver extensions didn't install. Deleted, restarted, tried again, failed. Third time...success. Correct USB option shows in Serial Port options, and it reads the engine on the track! Yay.

?

FWIW, yesterday I went through the JMRI debug page you cited and it was no help...

?

But, I'm up and running now, so it's back to the tutorials to remember how to use the programmer and other features!?

?

Thank you!
