This cable allows the signal to go from DCB device A to DCB device B and also from device B to device A. You don't need to swap cable ends when you want to send the signal the other way.
For example - this allows an MD-8 to control a Juno-60 AND the Juno-60 to control an MD-8, with no need to swap the ends of the cable round.
A 14-pin DCB plug on each side.
