Connecting a CVx to a MIDI 1U
If you use the optional CVx expander module, you will need to connect it to both power and to the
MIDI 1U module.
1. Turn off power to your case.
2. Connect the supplied 10-pin-to-16-pin power cable between the CVx and one of your case’
16-pin power connectors (using the same technique discussed earlier in Connecting Power to
the MIDI 1U ).
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 the CVx . The connector is keyed, and will fit in only one direction.
5. Set both DIP switches on the back of the CVx to the down position.
In the following example, we’ve set both DIP switches to their down positions, which identifies
the CVx as “Expander 1” (important if you chain together multiple CVx modules, as described in
the next section ).
6. Power up your case.
