To connect a 12 Step to an iPhone or iPad you will need to plug a USB cable from the port labeled 'USB' into an official Apple Camera Connection Kit.

In addition you will need to power your 12 Step externally. One way to do this is by plugging a USB-Mini cable from the port labeled 'Expand' into a powered USB port, such as on a USB power supply. The alternative way to power the 12 Step is by using a powered USB hub.
