Here's a quick reference to the ports on the back of your NEXT Hub necessary for connection.
Port 12 is where you will connect your power cable.
The ports in the red box are for connecting to your display. Connect an HDMI cable from HDMI OUT 1 to HDMI IN on your display. Then, connect the provided USB touch cable (USB A to USB B) from the TOUCH port on your NEXT Hub to the corresponding Touch port on your display.
The ports in the blue boxes are for connecting a PC. If you are connecting with USB C, plug your USB C to USB C cable into the USB C port on the far right, with the other end going into your PC. If you are connecting via HDMI, connect your HDMI cable to HDMI IN on the NEXT Hub, with the other end going into HDMI OUT on your PC. For touch, you will need to utilize the USB C to USB A cable that comes with your NEXT Hub. Plug the USB C end into the far right USB C port, then connect the USB A cable to your PC.
