Hi ogj,
I hope you are doing well today! We need to start from the base and build up. Do you have another Linux machine lying around? If so, try on there. Do you have another 6009 so you can try getting an output on that? Are you able to read inputs on the device? Also, how are you reading the outputs? Are you using a voltmeter? What version of NI-DAQmx Base are you using? NI-DAQmx Base 2.1.0f0 for Linux software for the Intel x86 architecture requires one of the following distributions: Red Hat Enterprise Linux WS 3, Red Hat Enterprise Linux WS 4, Mandrakelinux 10.1 Official, Mandriva Linux 2006, SUSE Linux 10.0, SUSE Linux 10.1. If you are not able to resolve the initial questions, I won't be able to help you much just because NI-DAQmx Base does not support Slackware's Linux distribution.
