Universal Serial Bus; Serial Ports - NCR 7448 Hardware User's Manual

1-10 Chapter 1: Product Overview
The wireless networks operate at maximum speed of 11 Mb/s with 2 percent
packet loss typical. The application developer must be aware of the
performance limitations and design applications that are acceptable to the
customer when run over the slower network.
Remote Wakeup over the wireless network is not possible because the cards do
not support it. An alternative is to use the system real-time clock wake up at a
scheduled time.
The wired Ethernet connection is not certified for use in configurations where a
wireless adapter is installed.

Universal Serial Bus

Two USB Type A ports are provided on the workstation. USB Host Controller
support is provided in hardware on the processor board.

Serial Ports

The workstation supports six RS-232 ports. Six 9 pin D-shell connectors are
provided. Those RS-232 ports are used to connect the optional module such as a
scanner and have +12V DC power on one pin. You can disconnect power by
BIOS menu setting if not needed by the device on the RS-232 port. Program
also can directly control the power setting on the pin.
