how can i write a pattern to a output port of NI PCI 6503 with Traditional NI DAQ 7.0 and Visual Basic 6.0?

[feder15]

Hello, i'm using a NI PCI-6503 (with CB50LP accesory) to write digital patterns to one of the output ports. Can i do it directly from NIDAQ7.0?

I know  some Visual Basic 6.0 functions to configure a par as output and to write a pattern to a port, but i don't know how run it.

I've read some examples from "Help" (C:\Program Files\National Instruments\NI-DAQ\Examples\VBasic\Do) but I can't measuring TTL levels on my CB50LP accesory.

                Thanks!!
