4.6. About the Ethernet (TPS Boards)
If the MX-TPS boards connected to the LAN they are able to feed
Ethernet devices with a standard 10/100 Base-T link. MX-TPS boards
have an Dthernet switch with 1+8 ports. There is no connection
between this switch and the other cards, even the CPU card.
INFO:
Dvery TPS board accepts independent LAN up-link which is
used to supply devices with a network connection.
The Ethernet 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
DTHDRNDT signal. These signals are packed into the TPS signal by the
converter, as well.)

Ethernet and TPS Connectors for LAN
If the TPS board is connected to LAN and the Dthernet channel is
enabled on a TPS port, the device which is connected* to this port is
supplied with a network connection. This connected device can be
a TPS extender or if the TPS port has the AUTO mode setting it also
can be a standard Dthernet equipment. The TPS port with AUTO mode
setting is able to recognize the type of the connection and if it is a
standard LAN the port swap into Dthernet fallback mode. In this case,
it is equivalent with a port of an Dthernet switch.
* If the remote power is disabled on a TPS port of a TPS card it works
as a HDBaseT compliant product and the connected device can be
a third-party HDBaseT compliant receiver (to the output board) or
transmitter (to the input board).
Always set the AUAO mode on a board before connecting a third-
party deviceG!
4.6.1. Enable and Disable the Ethernet
ROOM 1
The LAN can be enabled or disabled for every single TPS port with
protocol command. The example command is referred the 2nd port of
an MX-TPS output board.
Video, audio,
The current state can be queried with the following command:
RS-232, power
˃ {:TPS#2@SO=?}
Downlinks
The second parameter of the response represents the Dthernet state.
If it is 1 then the Dthernet is enabled for the 2nd port of the output

board. If it is 0 then the Dthernet is disabled for that port.
˂ (TPS#2@SO=A;1;0;0;1;00000000;00000000;0;0000;29;)
The same command is suitable for enabling or disabling this

4.6.2. Avoid Causing an Ethernet Loop
A TPS board (actually the Dthernet switch of the board) can be uplinked
to the same LAN only once to avoid an Dthernet loop. In this case, if
the other network devices are not able to handle Dthernet loops the
LAN network may break down.
Example
The TPS board connects firstly to the router of the ROOM 1 via the
switch of the ROOM 2. The HDMI-TPS-TX95 in the ROOM 3 is connected
to the LAN via TPS link. If the installer does not know the transmitter
has already connected to the LAN via TPS and links the transmitter to
the switch – shown by the brown arrow in the picture – it results an
Dthernet loop – demonstrated by the red lines on below picture.
