I have no BC22Q cables so I can't check.
BC22Q
the newer DSSI connector is straight, and will match an SF200/SF7x.
the older DSSI connector is rt-angle to fit under the cover of an
E.G. uV 3400,3900.
I could use a good catalog or other URL to images of all the connector
types, but it sounds right. I call the newer DSSI connector, informally, a
"mini centronics" and the older a "mini-IDC", if that helps to
illustrate
at all.
