We are using the PCI-7830R FPGA RIO card though this same query applies
to other FPGA cards and indeed to other cards that use VHDCI
connectors. We need to find a cabling solution to link between the
VHDCI connectors on adjacent boards. The board pitch is 0.8" on both
PCI and PXI and so the same solution would be appropriate for both. We
are also trying to keep it low profile.
We have looked at using the IDC versions of the plugs but since this
uses 2 IDC cables any such jumper would no longer be 1:1 wiring,
something that we're reluctant to do except as a last resort.
Another option that we've considered is making a custom jumper PCB,
even though this is not ideal as it imposes mechanical strain on the
jumper PCB. Also we have not been able to find straight PCB mount
versions of the plug (only right angled plugs even though there are
straight versions of the receptacle).
Any suggestions welcomed.
