NI-6581 FlexRIO adapter module - Can a single I/O port have some channel lines defined as inputs and some defined as outputs?

[EganM]

Hello,

I am using a 6581 Adapter module with 7965R FlexRIO FPGA module. The IO Module channel/Port CLIP allows for setting an entire port as either an input or an output, however I would like to set one channel line of a port as an output and the remaining seven channel lines as inputs, is it possible to do this ?

Thanks,

Maurice.

Hello Maurice,

The 6581 Adapter module can only change direction on a port basis (not on an individual line basis).  This can be seen in the specifications here.  There are other digital adapter modules that support per channel direction control like the NI 6583.  The NI 6583 35 single ended I/O, and LVDS (or mLVDS) I/O.
