NI PCI-6225 RTSI

[Dave]

I am using comedi version 0.7.76 on Ubuntu 10.04 with kernel 2.6.32. I
have two NI PCI-6225 DAQ cards. Both of these are recognized by comedi
and I am able to acquire samples on each of them.

I have an RTSI cable installed, but comedi does not list an RTSI
subdevice ( ID = 10 ) for either board. Do I need to configure comedi
to recognize the RTSI?

Thanks for the help.

It should appear as a DIO subdevice (although you can't actually read or
write any meaningful data from/to the channels). It responds to various
INSN_CONFIG instructions to set/query the directions, clock sources and
routing. Comedilib has some demo programs called dio, choose_clock, and
choose_routing to configure this stuff. (The CVS version of comedilib
also has some wrapper functions around the INSN_CONFIG instructions to
configure this stuff.)
