Hi Team,

My customer now want to use 949's Dout1 to connect with 926 in instead of Dout0, because of some PCB layout error...

But as customer's feedback, even they open the pass through, there is no link between 949 and 926.

When 949 connect with ALP, they can't detect 926.

So do we need to configure other things if 949's Dout1 connnected with 926 instead of Dout0 connected with 926?

Hello Amelie,

you need to select : 0x1E[1] select Port1

Hi Hamzeh,

Thanks for your reply.

Customer set 949 0x1E =0x05, which has select Port 1.

And also open the pass through in 949 and 926.

But when it read the 926 register,all of them are zero.

since 926 and 949 are connected successfully, why 926 can't be really successfully?

Hello Amelie,

I have checked this on my desk and I could see the same behavior you are describing.

I will discuss this internally with the team and come back to you.

Hello Amelie,

I have checked on my desk; you need to set register 0x1E=0x06, then it should work.
