Configuring Power To A Serial Port - HP Rp3000 - Point of Sale System Hardware Reference Manual

Configuring Power to a Serial Port

The serial ports on the HP Point of Sale System computer can be configured as standard (non-powered)
serial ports or powered serial ports. Some Point of Sale 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.
NOTE: The computer ships with all serial ports configured in standard serial mode by default unless
the powered serial port AV numbers are ordered.
The serial port jumpers on the system board are located as shown in the following illustration:
