USB-6221 DIO: Active Drive or Open Collector?

[BjornDeb]

Hi,
I am planning to switch from the USB-6501 to the USB-6221.
 
With the USB-6501, the type of the output drive can be configured to "Active Drive" or to "Open Collector" (push-pull or open drain). Based on the data-sheets of the USB-6221, I cannot find this feature on the USB-6221.
 
Do you know if this feature exists for the USB-6221? If it doesn't exist, any idea what its fixed state is?
 
Thanks!

Hi Bjorn,
 
You are fully right. You can't do this with the USB-6221. You can find the spec of a the 622x devices in attachement.
