Using Communications Devices - HP Compaq tc1100 Reference Manual

Using the Tablet PC Docking Station and Screen Protector
A USB hub is a connecting device that can be powered or
unpowered. Powered hubs must be connected to external power.
Unpowered hubs must be connected either to a USB connector
on the Docking Station or to a powered hub. USB hubs can be
connected to a USB connector on the Docking Station or to other
USB devices. Hubs support varying numbers of USB devices and
are used to increase the number of USB devices in the system.
Some USB devices may require additional support software,
which is usually included with the device. For software
information about a specific device, refer to the documentation
included with the device.

Using Communications Devices

To connect the system to a network when the tablet PC is docked
to the Docking Station, insert the network cable into the RJ-45
network jack on the back of the Docking Station and not into the
RJ-45 network jack on the tablet PC.
Ä
CAUTION: Simultaneously connecting network cables into jacks on the
tablet PC and Docking Station will cause degraded network access or
may cause network access failure.
Wired network connectivity and activity are indicated by the
Local Area Network (LAN) connection lights on the top of
the tablet PC (when the tablet PC is in the portrait position) or
on the left side of the tablet PC (when the tablet PC is in the
landscape position), even if the network cable is plugged into
the Docking Station RJ-45 network jack. Wireless network
connectivity and activity are indicated by the wireless LAN
activity light on the front of the tablet PC. Refer to the Hardware
Guide on the Documentation Library Tablet PC Series CD for
more information.
To use the tablet PC internal modem while docked, use the
tablet PC RJ-11 telephone jack located on the lower side of
the tablet PC.
