Note 1

14 pin IEEE DCB to 14 pin DCB cable
one direction only -2 metres

Used for connecting two pieces of DCB equipment to each other. This cable is fine if the signal direction is always in the same direction - for example, where the sequencer always plays the synth.

For example, this cable allows an MD-8 to control a Juno-60.

This cable allows the signal to go from DCB device A to DCB device B. If you want the signal to go from device B to device A then you will need to unplug the cable and plug it in the other way round.

Note 2

14 pin IEEE DCB to 14 pin DCB cable
both directions -2 metres

Used for connecting two pieces of DCB equipment to each other - this cable is more convenient if you want the ability to change control signal direction without the need to swap the cable round.

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.

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
