Configuring Powered Serial Ports - HP vc4820T - Thin Client Hardware Reference Manual

Configuring Powered Serial Ports

Three configurable, powered serial ports, COM 2, COM 3, and COM 4, are standard on the thin client.
COM 1 is a standard, non-powered serial port that cannot be configured. Some devices use a powered
serial port. If the serial port is configured as a powered port, devices that support a powered serial
interface do not require an external power source.
