5. Click Next.
The PC locates the driver and installs it.
6. When the Completed dialog opens, click Finish to close the wizard.
NOTE: The wizard opens only on the first occasion you connect the SMP351 to
a USB port. The wizard reopens only if you connect the SMP351 to a different
USB port or if you connect a different piece of equipment, requiring a different
driver, to the same USB port.
7. Configure the SMP351 as required.
Ethernet (LAN) Port
The rear panel LAN connector on the device can be connected to an Ethernet LAN or
WAN. Communication between the device and the control PC is via Telnet (a TCP socket
using port 23). The Telnet port can be changed, if necessary, via SIS or using the SMP351
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.
• Crossover cable — Direct connection between the computer and the SMP351.
• Patch (straight) cable — Connection of the SMP351 to an Ethernet LAN.

Pins:
A cable that is wired as TIA/EIA T568A at one
end and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable wired the same at both ends is called
a "straight-through" cable because no pin/pair
assignments are swapped.

To establish a network connection to the SMP351:
1. Open a TCP socket to port 23 using the SMP351 IP address.
NOTE: If the local system administrators have not changed the value, the
factory-specified default, 192.168.254.254, is the correct value for this field.
2. The SMP351 responds with a copyright message including the name of the product,
firmware version, part number, and the current date/time.
a. If the SMP351 is not password-protected, the device is ready to accept SIS
commands immediately after it sends the copyright message.
b. If the SMP351 is password-protected, a password prompt appears below the
copyright message. Proceed to step 3.
