6537

[leosgb]

Hi,
 
I am trying to acquire some digital samples (2 x 16 bits in one PCIe 6537) using Burst handshake protocol. I have the cable adapter configured as follows:
 

6537 side          6533 side                  desc.
4                        4                                Clock
1                        6                                Ack
0                        2                                Req
 
Surprisingly nothing happens when I have my clock (in the VB .NET program) set to PFI4. But when I change it to PFI5 I get an ACK signal on my peripheral.
 
I noticed that nothing happens in the clock on the peripheral, though.
 
I wonder if I am supposed to change my cable adapter so that it connects PFI4 from my 6533 side (peripheral) to PFI5 in my 6537side. Is this right?
 
I have another thread treating of this issue but from the programming side at:

Thank you.

Hi leosgb:The 6537 doesn't support the clock on PFI4 for input (i.e. PFI4 as a clock is supported for only output).  It's not working because your not catching the configuration error or your code is ignoring the configuration error.Jeffleosgb wrote:
