This had fixed, protruding female receptacles (huh? What the heck is that?) as if one would screw the device onto the connector. First the connector came with fixed and reserve attachment: old SCSI/parallel connectors had recessed ports with screws so you could screw the male end into the female lock on the device. Dumb design, poor documentation, driver on obsolete mini-CD, no info or drivers on questionable website.
