Ethernet (RJ-45) signal distribution module
Ethernet for Eurorack!
Well, not exactly... this is a passive module that uses an RJ-45 jack for distributing signals between two modular systems: across the table, across the room, or even across a stage (if you don't need precision). Put those old Ethernet cables back to work!
Ethernet cables carry 8 signals but this module uses pin 8 to provide a common ground between cases, so you get a total of 7 patch points.
