In MMX8x4-HT400MC and MMX8x4-HT420M models
Crosspoint state: Switch the desired video input to O5. For more details, see
chapter, for LW3 command see Switching and Crosspoint Settings
Port status: Unmute the necessary video port. For more details, see the
chapter, for LW3 command see Query the Status of Source Port
Input port properties: Set the Audio mode to HDMI audio passthrough.
This setting can be found only in I5 and I6 ports of MMX8x4-HT420M model. HDMI audio passthrough is the
default audio mode in the other ports and this property can not be changed.
Audio mixer (advanced audio settings) for I11 audio port: Set the volume and the gain, unmute the channel. For
more details, see Legend of Embedded or Advanced Input Channel
Embedded Audio Input Settings section.
INFO:
Choosing the input channel in the drop-down list is equal with switching an input port to O5.
Audio mixer (advanced audio settings) for O6 audio port: Take care of the proper mute state and volume value. For
more details, see Advanced Analog Output Channel

5.5. Ethernet Interface
The device can be controlled via Ethernet port (RJ45 connector). This interface supports any third-party
system controller with LW2/LW3 command protocol. The interface can be used to configure the device with
Lightware Device Controller and establish the connection to Lightware Device Updater software and perform
firmware upgrade.
Serial and infra messages can be sent and received via Control Ethernet port (See more details about it in
Serial Interface and Infra Interface
INFO:
In MMX8x4-HT400MC and MMX8x4-HT420M models, TPS lines do not transmit Ethernet signal,
but the matrix is able to receive TCP/IP commands via Control Ethernet port. In case of MMX8x4-HT420M
model Ethernet signal transmission is possible via TPS lines, but it needed physical link between the
boards. For more details see the the next section.
Third-party Device Control via MMX8x4-HT420M
in LDC MMX8x4-HT420M model contains RJ45 connector to supply Ethernet communication for the TPS lines.
Ethernet commands can be transmitted on the TPS input and output ports if there is a physical link between
the motherboard and the input or the output board.
in LDC
Ethernet Link to TPS I/O labeled connector on the I/O card is connected to the switch directly.
The other TPS input and output ports are connected to the switch via a converter. (This converter is able to
separate the incoming TPS stream into video, audio, RS-232, power and Ethernet signal. These signals are
packed into the TPS signal by the converter, as well.)

INFO: The LAN can be enabled or disabled for every single TPS port with Lightware Device Controller
(LDC) software or LW3 protocol command.
Ethernet Link to TPS ports
Create a link towards the TPS input ports by connecting a patch cable between the two RJ45 connectors:
