NI9264

[john_69]

Is it possible to serialize the NI9264 outputs ? (common ground or not) ?

Hi John!

Here's a few resources that may answer your question. 

Different Types of Isolation: Channel-to-Channel, Bank (Channel-to-Bus), and Channel-to-Earth Ground Isolation

Looking at the manual for the 9264, it appears that the 9264 is not channel-to-channel isolated, and only Channel-To-Earth Ground Isolated. The channel-to-earth ground isolation only protects the channel grounds from the ground on other background processes, such as the power supply. Thus, the 9264 AO channels do share a common ground only to each other.
