AiM two-port data hub with a 1.5m cable that connects two devices to your MyChron through one cable, for example a SmartyCam or a lambda controller. It also connects to the kart's battery to power the MyChron and whatever is plugged into it.
*Note: This requires battery power, if you have a 206, shifter, or any kart that does not feature an onboard battery, a 12V source would need to be added.
