I'm in the same boat as Captain1313, don't have a dcc meter.  I will fiddle with the consist idea.  I'm still uncertain about changing individual cv values.  Nervous about it also.

I think there is something related to the Pro Box as The captin suggests.  That pin connection looks fragile and prone to bending or breakage.  I wonder if that causes unhappy bit and byte transfer....

You wouldn't happen to be running the "Pro" version of the Dynamis system, would you?

So here's the thing.  I ran both the proto2000 F7A&B with QSi decoder and the MTH locomotives on the track with Dynamis Pro at the same time with no IR signal issues at all.  They ran perfectly and there was no problem with the IR signal. 

Then I ran the proto2000 F7A&B again on Dynamis Pro by themselves and they ran great for a few minutes but I then encountered the IR signal issue again.  Then I separated the A&B units reprogrammed them and both ran separately with no IR signal issue.  I put them in a consist and they didn't run at all.  Took them out of consist and the IR signal problem occurred again intermittently.  Took the Pro box off (converted it back to regular Dynamis) and they seemed to run fine again with no signal loss. 

I think there is something going on with the Pro Box and the QSi decoder. How do we get Dynamis to work with QSi to troubleshoot?

Does it have a QSi decoder?  I have a proto2000 with similar issues using Dynamis pro.

I got the same response.  The classic hardware, software conflict and no one's fault.  Just the customer's problem because neither wants to spend the time and money resolving the conflict.

I agree with him in that it can't be the wireless handset.  It's somewhere between the decoder and the controller. But it's odd that the problem manifests itself when a new input is transmitted to the receiver from the handset.  Must be a bits and bytes conflict between the controller and the Qsi decoder.  I will try the other loco and removing the Pro box and see what that does and report back. 

Kevin,

That's a good tip.  I will try it without the Pro attachment. I will also try my MTH Dreyfus Hudson dcc on it again to eliminate the handset hardware as the problem.  You may want to alert Norm Stenzel of QSi solutions (http://www.amhobby.com/) because he hadn't heard of the problem until I reached out to them on their website yesterday.  His email is [email protected] and it will be good for him to become aware of others having similar problems with the QSi chip.  My proto2000 was a QSI chipped decoder as well!

I am experiencing a signal issue when using the Dynamis pro with a proto2000 HO F7a/b.  when I accelerate, the signal goes dead, then comes on intermittently, then goes to STOP mode.  The system works fine on my N gauge dcc track.  Any ideas on how to get this sorted out?
