Connecting Multiple CVx Modules to a MIDI 1U
You can connect up to four CVx modules to a single MIDI 1U module — creating an expansive and
powerful MIDI-to-CV controller for your eurorack system. Each CVx has two I2C jacks, allowing
them to be chained together, with their dip switches each set to a different address. Specifically:
1. Turn off power to your case.
2. Connect the 10-pin power connector on each CVx to your power supply using the included
10-pin-to-16-pin power cable.
3. Connect one end of the supplied 6-pin to 6-pin ribbon cable to the 6-pin I2C connector on the
MIDI 1U module. The connector is keyed, and will fit in only one direction.
4. Connect the other end of the supplied 6-pin-to-6-pin ribbon cable to either one of the 6-pin I2C
connectors on CVx #1 . The connector is keyed, and will fit in only one direction.
5. Set the dip switches on the back of the CVx to give it a unique ID.
You can connect up to four CVx units to your
MIDI 1U — each of which requires its own ID
(1-4) as set with the dip switches on the CVx’
back panel.
6. Connect the remaining I2C-2 connector on CVx #1 to either I2C connector on CVx #2, and set
CVx #2’s dip switches to a different ID than you used for CVx #1.
7. In the following example, CVx #1 has both dip switches to their down positions, identifying it as
“Expander 1,” while CVx #2 has the “1 switch” in the up position, identifying it as Expander 2.”
8. Continue chaining additional CVx modules as needed; setting each CVx’ dip switches to a
different ID.
9. Power up your case.
