NOTE: There are three SIS commands you may find useful at this point:

LAN (Ethernet) Port

The rear panel LAN connector on the device can be connected to an Ethernet LAN or WAN.
Communication between the device and the controlling PC is via Telnet (a TCP socket
using port 23). The Telnet port can be changed, if necessary, via SIS or using the SMD 101
user interface. This connection makes SIS control of the device possible using a computer
connected to the same LAN or WAN. The SIS commands and behavior of the product are
common to the commands and behavior the product exhibits when communicating by
serial port or USB.
Ethernet Connection
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application (see figure 103).

Select Install the software automatically (Recommended) (see figure 102,
on the previous page).
NOTE: You do not need to insert an installation disc.
Click Next ( ).

The PC locates the driver and installs it.
When the Completed dialog opens, click Finish to close the wizard.
NOTE: The wizard opens only on the first occasion you connect the SMD 101 to a
USB port. The wizard reopens only if you connect the SMD 101 to a different USB
port or if you connect a different piece of equipment, requiring a different driver, to
the same USB port.
Configure the SMD 101 as required.

Pair Wires
A cable that is wired as TIA/EIA T568A at one
RJ-45
end and T568B at the other (Tx and Rx pairs
Connector
reversed) is a "crossover" cable.
