how to connect 8 Analog output channel

[zhoulmnk]

I just bought PCI 6733 card which has 8 AO channels. The teminal block with this card is SCB-68 M Series Devices. From the Quick Reference Label on the terminal block, there are 2 AO channels. I am not sure where should I connect another 6 AO channels.If I connect to some PFI channel as AO channels, do I need specify the channel in my code? I am using VC++ to code.

Thanks!

the SCB-68 is a terminal block that is used for most of our 68-pin devices, but may not be fully labeled for an AO board like the 6733.  The numbers, however, should be correct.  Try looking at the device specific section of the daqmx help (start menu->national instruments->ni-daq->ni-daqmx help) and look for the section "NI-DAQmx Device Terminals Help"

HI,

I connect the PinOut for the AO3:7. But they didn't work. Should I do some physical connection on the SCB-68 terminal block? Such as connect the AO 3:7 ground to AO0:1 ground?

Be sure you set the switches on the SCB-68 to "direct feedthrough mode" (see attachment)

You should be able to connect AO+ to the AO2:7 pins as shown in the picture I originally posted and you can connect AO- to any AO Ground.  That should work.  How are you verifying that "they didn't work"?  Do you have a scope or something hooked up?

Thank you!

I connected the channel to the scope. But I didn't set the direct feedthrough mode. I will try it.
