"Single-ended" does not mean that the adapter only has a cable
going out from it in one direction.  It means that of each pair
of bus lines, one is signal and one is ground.  This is as
opposed to "differential" which uses positive/negative pairs
of lines to carry signals.  Or something like that.

As someone else said, you can plug any of the connectors of
a regular SCSI cable into the adapter, assuming the termination
options allow it.  (I.e., end of cable -> terminated; middle of
cable -> unterminated.)
