Note
Before you select a LAN speed and duplex mode, find out from your
network administrator what speed and duplex mode are supported
by the switch to which your system is connected.
❑ Select LAN Port—The ViewStation supports a LAN port and a
PC port:
• The LAN Port option represents the LAN port on the back
of your system. This port is used to directly connect your
system to your LAN network.
• The other port, the PC Port, can be used to connect a device
to the LAN network through your system (which, in this
case, acts as a hub), or to directly connect a device such as a
PC to a system not on the LAN network.
❑ LAN Speed—This option can be set to Auto, 10 MBps, or 100
MBps (megabits per second).
•Auto: When this option is selected, the network switch to
which the system is connected automatically negotiates the
LAN speed and duplex mode.
• 10 MBps or 100 MBps: When one of these LAN speeds is
selected, a duplex mode must be selected (see Duplex
Mode below).
❑ Duplex Mode—This option can be set to Auto, Full, or Half.
•Auto: When this option is selected, the network switch to
which the system is connected automatically negotiates the
duplex mode.
•Full: This duplex mode allows for bi-directional,
simultaneous, two-way communications.
•Half: This duplex mode allows for bi-directional data
transmission, but not at the same time.
