Avoid Causing an Ethernet Loop
A TPS board (actually the Ethernet switch of the board) can be uplinked to the same LAN only once to avoid
an Ethernet loop. In this case, if the other network devices are not able to handle Ethernet loops, the LAN
network may break down.
Example
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 in an Ethernet loop – demonstrated by the red lines on the picture below.

Basic Concept
There are three operating modes of the LCD menu.
Normal Mode
Most settings can be done in this mode. It is active when none of the EDID or the SIGNAL PRESENT button
shine.
EDID Mode
Use this mode to set up the emulated EDID on the inputs, learn EDID form the outputs or to view the EDID
memory. Enter or exit this mode by pressing the EDID button. The illuminated EDID button shows that this
mode is active.
Signal Present Mode
This mode is for checking the presence of incoming signals and display devices. Enter or exit this mode by
pressing the SIGNAL PRESENT button. The illuminated SIGNAL PRESENT button shows that this mode is active.
