PCIe-1473R camera link frame grabber using I/O ports

[cychang0829]

Hi, dear all,

We are using PCIe-1473R to capture camera link camera at high speed and do computation in the FPGA. After the computation, we need to output I/Os signals to commnicate/comtrol other components. I have searched the documnets and manuals as many as I can find. The possible I/Os I can access is listed as follow:

We have:

1 x "I/O Extension Board Connected": can be assigned only read

3 x "ISO in": can be assigned only read

3 x "ISO out": can be assigned both read or write

2 x "QE phase": can be assigned only read

8 x "RTSI": can be assigned both read or write

9 x "TTL": can be assigned both read or write

I know the RTSI is used for the board-to-board communication and others are used for the 50-pin I/O extension board. However, Basically they should be just normal I/O ports from FPGA, right? I might be able to use them as normal I/Os and pull them out directly from 1473R no matter what their names are (ISO, QE...etc).  Or Does NI have special circut and speed design for them individually?

If they are the same, it means I have 20 I/O ports which can be assigned both read or write. Does anyone know the exact pin assignment for these ports?

I can only find the RTSI pin assignmenrt: (http://digital.ni.com/public.nsf/allkb/392DEFA8A72CA693862572E300651A9F)

Thanks in advance.

Best.
