FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does part number 779973-04 use SCSI signal connectors?

NI lists 779973-04 as a screw-terminal USB-6225. SCSI connectors belong to the mass-termination version, so the legacy connector description should not be used to select accessories for this part number.

How many differential analog inputs are supported?

The USB-6225 supports up to 40 differential inputs, or up to 80 single-ended inputs.
