For the controlCARD to operate, the controlCARD MCU must be powered. This can be done through the USB-connector on the controlCARD or by inputting 5 V through the HSEC connector by way of an accompanying baseboard. For example if using a TMDSHSECDOCK docking station baseboard, 5-V DC can be input into the docking station J1 or J17. Then, S1 on the docking station needs to be toggled to the appropriate position.
