I have programmed a single DR5033 after installation but not with several DR5033's connected.
Was just wondering from you post and have a few questions.
1. I assume you verified all the ID's of each Booster before installation.
2. After installation, did you do a test you could read a CV value on each Booster?
3. I am thinking you might have duplicated a ID# or one got changed.
Maybe someone else can chime in here.
