How can I generate serial data (or a custom digital signal) output using USB-6008

[Bessam]

I'm trying to use the USB-6008 to generate/simulate serial data output on P0.0, basicly I need to create a digital signal profile with zeros and ones. each bit has a time length of 8.192ms the pattern of these zeros and ones repeats every 163 bits. i don't know where to start? please help

thank you

To add to the above, I'm using Labview 7.1 student version

A simple way would be to wire a Boolean array through a for loop with a DAQmx Write inside.

I hope your 8.192 ms is an approximate rate. The 6008 is software timed and with a windows OS, you will see considerable jitter.

Thank you for replying, with regards to the bit time of 8.192ms i do have an older DAQCard-512 with NI-DAQ 6.9.3 would this be able to achieve this timing?

I'm not familiar with that card. If you have the specs, see if the digital I/O is hardware timed.

I applogise the correct model number for the card is DAQCard-516 not DAQCard-512

The manual is here. It seems the digital I/O is software timed.
