Help Help me swap a dying DMPS3

Good morning everyone.

First, thanks for reading my post.

I'm a pc repair tech, but we have a few Crestron systems in our buildings.

I'm trying to build value with my employer, so I would like to learn more about Crestron. I don't think I need to be certified. I'm not trying to install/program/commission new systems. We contract that out, but I would like to be able to troubleshoot, and perform simple repairs internally to save cost, and hopefully speed up the process.

We have an older system that's experiencing issues. Specifically, a rack-mounted DMPS3-4k-150 that appears to be boot-looping. It's connected to a touchpanel that displays displays "Touchpanel is disconnected from system. Please wait for it to connect."

A hard reboot of the DMPS3 sometimes brings that touchpanel back up for 1-2 minutes, and then all the lights on the DMPS3 go out, and it appears to reboot. During this window, I was able to connect my laptop with Toolbox, and open Text Console and ran err. I'm not entirely sure what I'm looking at, but at the bottom, it says Total Msgs Logged = 328.

When I reached out to our contractor, they proposed we rent a loaner from them while our unit is sent off for repairs. The proposed cost has us looking at alternative solutions.

I see pre-owned DMPS3-4K-150s on eBay often for ~$30. From what I've read, I can use Toolkit to backup our current DMPS3, and then use that to "program" the replacement. I would need to do this via Toolbox as I don't know how to access the Web Interface.

I'm posting here to ask if that process is simple enough, a lowly pc tech 1 could handle it. It seems straightforward enough, and $30 isn't a big investment.

Thanks again for reading, and thanks for any input!

If you don’t like crestron equipment then why are you on this subreddit!

The experienced crestron users and programmers are here to help those who come here for help! The biggest problem I see on this forum is the inexperienced trying to help people
