This is a guide to understanding what your provided Lightning - Mini-DIN does when it's connected to your Evermix MixBox. The cable is very expensive and needs to be looked after very carefully.
The cable is designed to allow audio data to be transferred from your MixBox to your device but not only that it draws power from your device to allow the MixBox to function.
Mini-DIN to Lightning port sends:
Pin 1 (Bottom-Right) - Common Ground
Pin 2 (Bottom-Left) - Receives Data
Pin 3 (Middle-Left) - Transmits Data
Pin 4 (Middle-Right) - Power Supply to MixBox
Pin 5 (Top-Right) - Power Supply
Pin 6 (Top-Middle) - Power Supply
Pin 7 (Top-Left) - Device Availability - This pin notices the device plugged in.
WHEN CONNECTING THE MINI-DIN TO LIGHTNING CABLE, ENSURE YOU LINE UP THE PINS CORRECTLY.
