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.

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.
