Switching mode cannot be selected when the VGA port is set for Component or
Composite video input. When Auto Switching is enabled, the Scaler/Switch will
perform as follows:
Whenever a new input signal is detected, it will automatically switch to that
input.
If Auto Switching mode was enabled when power is lost, once power is
reapplied, the unit will query all inputs from 1-5 for an available signal. It will
then automatically switch to the first input found.
If the active input is removed, the unit will query all inputs from 1-5 for an
available signal. It will then automatically switch to the first input found.

CONFIGURING FOR TCP/IP CONTROL
If you connected the matrix/transmitter to an existing network, there is no special
configuration required. However, if you connected your PC's network interface directly to
the TCP/IP jack on the
matrix/transmitter, you will need to
configure your PC's network
settings to communicate with the
matrix/transmitter. The
matrix/transmitter uses the
following network settings:
IP Address: 192.168.0.178
Subnet Mask: 255.255.255.0
Gateway: 192.168.0.1
The default IP Address, Subnet
Mask, and Gateway can be
changed using the TCP/IP GUI
interface.
15
Page 16
VGA INPUT
The VGA input can accept VGA, Component (YPbPr), and Composite (CVBS) video signals.
The unit will automatically detect the input type and will convert and scale it to the HDMI®
output.
When connecting to a VGA input, use a standard HD15 VGA cable.
When connecting to a Component (YPbPr) video source, connect the Red, Blue, and
Green plugs to the corresponding video outputs on your Component source device.
When connecting to a Composite (CVBS) video source, plug the red connector into
the video output (normally yellow).
AUDIO OUT CONNECTION
The AUDIO OUT terminal block features + and - terminals for each of the two
channels (L and R), plus a common ground connection.
If making an unbalanced connection, connect the + and - leads to the + and -
terminals and leave the ground terminal unconnected.
If making a balanced connection, connect the + and - leads to the + and - terminals,
then connect each channel's ground to the common ground terminal.
