These panels can be supplied in a standard wall mounted electrical box. Physical installation is outlined here. To understand how to set up the software refer to the Artist Help.
The panel is supplied with a 5Volt DC power supply which is connected to the panel via the terminal block. It interfaces to a computer via the COM ports (RS232). You can add as many panels as you have free COM ports.
Great care must be taken in making this connection as reversing the polarity of the power supply will result in damage to the control panel electronics.
