FF answer for Register ID PXI 6509

[chat-relotte]

Hi All,

I am using register level programming to program my PXI 6509. I am using a chassis with a PXI 8106 controller.

I manage to initialize the device, to read the manufacturer ID and the model. But when I reads the ID Register, I always get the answer "FF". Moreover, when I configure the P0 port for output and tries to update the value of the port to 1, the outputs are not at the value 5V.

I have linked my C code (I am using CVI).

Do you have any idea why I am getting the answer "FF"? Why are the values of the outputs not changing?

Many thanks in advance for your help,

Charlotte
