Pin assignment of the multipin cable
Pin assignment of the multipin cable
The 40 lead multipin cable is used for the additional digital inputs
(on analog acquisition boards only) or additional digital outputs (on
analog generation boards only) as well as for the digital I/O or pat-
tern generator boards.
The flat ribbon cable is shipped with the boards that are equipped
with one or more of the above mentioned options. The cable ends
are assembled with two standard 20 pole IDC socket connector so
you can easily make connections to your type of equipment or DUT
(device under test).
The pin assignment is given in the table in the according chapter of
the appendix.
IDC footprints
The 20 pole IDC connectors have the following footprints. For easy usage
in your PCB the cable footprint as well as the PCB top footprint are shown
here. Please note that the PCB footprint is given as top view.
The following table shows the relation between the card connector pin and the IDC pin:t
