Hello Christopher,
Actually yes, there is the
PR68-68F cable that connects to non-latching E Series DAQCads and directly to 68-pin accessories. This cable would go with your card.
There's also a different cable called the
SHC68-68-EP that goes with the newer latching DAQCards. These are good because you don't have to worry about the cable falling out so much.
