What is the USB port on the oxygen concentrator used for?
Universal Serial Bus (USB) is an industry-standard that establishes specifications for cables, connectors, and protocols for connection, communication, and power supply (port) between computers, peripherals, and other computers.
USB was designed to standardize the connection of peripherals to personal computers, both to communicate with and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports and has become commonplace on a wide range of devices. Peripherals connected via USB include computer keyboards and mice, video cameras, printers, portable media players, mobile (portable) digital telephones, disk drives, and network adapters.
On stationary or portable oxygen concentrators, there is a USB port that is not easily found, because most users will not touch this port when using it.
So what is the function of setting such a USB port? In most maintenance manuals you will see the following prompt “The USB port is for service use only“. The USB port on the oxygen concentrator is mainly used to read the “error code” when repairing the equipment and to control the error program, but it needs to be connected to a debugging box dedicated to maintenance. The debugging box can be obtained from the manufacturer or an authorized service provider.
