The 4:1 Smart Jumper Block can ONLY be used with the Gen V Battery Rack Battery Rack - it is used to connect an existing PRO Lower Junction Box (PRO 2/CinemaHD/Cinelive) to the Gen V Battery Rack. It is NOT compatible with older PRO Battery Racks as the pin spacing is different.
Please find more information about our Smart Jumper Blocks here and feel free to reach out with any additional questions!
