Re: DP timing out talking to Command Station


 

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?

Hi folks-
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).

DP starts and appears to run OK, except that in trying to read from the decoder to set up a new loco I get timeouts (See first image). I¡¯ve tried each of the 6 different port options (second image) in both Programming Track and Programming on the main options - all with the same timeout.?

I thought the issue might be the LB-USB, but the green LEDs are on and on the DP window at the bottom it says LocoNet is online. I also tested the cable I¡¯m using to connect the LB-USB to the Zephyr and it is good.

So I¡¯m stumped. Any thoughts on why the connection is timing out?
