USER MANUAL
Web Server Introduction
The SB3M has a built in webserver to give you the ability to setup, troubleshoot, and control your system. To
access the webserver all you need to do is type in the IP address of the unit into your preferred web browser
and the log in screen will appear.
By default the SB3M will have the IP address of 192.168.2.175 which can be changed either through the
webserver itself or through the Rs232 port using the supplied commands.
To access the product web server if your network IP configuration differs from the default, or the product will
not be on a network, you can directly connect a computer LAN port to the SB3M’s LAN port with a straight
RJ45 cable. After making the connection you will need to access your network connection properties of the PC
and revise the settings to a static IP that is on the same subnet as below. Once done, you will be able to open
a web browser and enter the 192.168.2.175 to access to the web server.
If your SB3M will be connected to a local area network, please update the System settings in the SB3M
webserver system tab to match your local network. For example if the Lan IP is set as 192.168.88.xxx, then
please revise the product to 192.168.88.1xx. Once the IP is set, then you will be able to access the device
from any PC in the same network.

use. See section on switching modes for further help.
The Active Input and Output fields will tell you which source and what resolutions are moving thru the system.
Embedded or External Audio
For audio the SB3M is equipped with an independent audio embedder that is capable of taking stereo line
level audio thru its 3.5mm TRS phone jack input located between the VGA and LAN ports. When audio is inserted into this jack, it then may be selected for embedding. The SB3M can either use the existing embedded
audio (on HDMI or Display Port only) or you can choose to insert your own audio stream to be converted and
sent thru the HDBase-T link to the receiver. When you are using the VGA input the unit will always default to
the external audio setting as there is no embedded audio carried with the VGA video signal. The audio settings can be accessed thru the webserver, or by Rs232 commands.
Front Panel Button
The front panel button can be programed to behave in three different ways. It can be Enabled, Disabled, or
set to Rs232 Mode.
