DS90UH948-Q1: Pairing with UB947

Part Number: DS90UH948-Q1
Other Parts Discussed in Thread: ALP

Team,

My customer was using UB947+UB948 before and the panel could work. Due to UB948 shortage, they use UH948, but the panel couldn't be lighten up. 

I use ALP and check the UB947-Q1 and UH948-Q1 is locked.

Could you let me know the how could I check the issue? Is it possible that UB947 old version couldnt support pairing with UH device? 

System setup is showing as below.
