Accessing all 40 DIFF inputs on USB-6225 using BNC

[jarjarvai]

Hi All, 

I'm trying to set up the USB-6225 such that all 40 DIFF inputs can be accessed through BNC breakout connectors. So far, I've identified the BNC 2090A for accessing 8 channels on port 0 and BNC 2115 for accessing 24 channels on port 1. However, this leaves 8 DIFF inputs on Port 1 inaccessible, since the BNC 2115 would be connected through this port. Is there perhaps a way to access these 8 channels via some other connection? Thanks in advance!

You might want to consider using the SCB-68 or SCB-68A instead of BNC to have access to all 40 Diff channels. Here are a couple of resources that might be helpful:

Hi Brian, thanks for your response! My application requires something more robust than bare wire connections, which is why I was looking at the BNC connectors. I guess the best option at this point is to go for another USB-6225.
