3. Product Overview
Above settings refer to the matrix. The table below details the system's state with regard to mode selection
behavior for all possible combinations for both ends of the link:
MMX8x4-HT400MC
LPPF1
LPPF1
LPPF2
HDBaseT
Long reach
Auto
* If there is valid HDMI/DVI signal is on the TX side, the TPS mode will be HDBaseT on both side. If the
transmitter does not transmits HDMI/DVI signal, the TPS mode will be changed to LPPF1 automatically.
MMX8x4-HT420M
LPPF1
LPPF1 LPPF1
LPPF2 LPPF1
HDBaseT LPPF1
Long reach LPPF1
Auto LPPF1
* If there is valid HDMI/DVI signal is on the TX side, the TPS mode will be HDBaseT on both side. If the
transmitter does not transmits HDMI/DVI signal, the TPS mode will be changed to LPPF2 automatically.
Long reach mode is not available when both sides are set to Auto mode.
When using automatic operation mode selection, the device uses built-in sensors to determine the mode
of operation. If both parties are set to Auto mode, the source side is the initiator. It will negotiate each state
transition with its sink side partner.
When one of the devices is configured to manual operation mode selection, the other device may be placed
in automatic mode. In this case, the mode transition negotiation is initiated by the host-managed device and
the auto-mode device follows through. The allowed cable lengths and resolutions are listed in
Extension Distances section.

MMX8x4-HT series – User's Manual
3.5.2. Power over Ethernet (PoE)
WARNING! The remote power feature of TPS 95 series extenders is not PoE-compatible. Thus, TPS 95
series cannot be powered remotely by the MMX8x4 matrix switchers (but the video signal is transmitted
to/from the extenders). If a TPS 95 extender is connected to the matrix, make sure that the remote
power jumper of the extender is removed or set to 'Remote power disabled' position.
MMX8x4-HT420M
INFO: MMX8x4-HT420M model has PoE support.
TPS input and output ports are able to supply other HDBase-T compliant devices over the TPS lines which
are PoE-compliant as well. In this case, the connected transmitter or receiver does not require a local power
supply.
ATTENTION! The Ethernet ports do not support PoE. Only the TPS ports have PoE function.
The PoE feature in the practice
The TPS ports of the matrix are in accordance with IEEE 802.3af (PoE) standard. The feature is demonstrated
on below figure:
Auto
LPPF1
LPPF2
HDBaseT

transmitter
The concept
Supply the connected extenders through the CATx (TPS) cables without local adapters.
Settings
Maximum
Extenders: the device must be PoE-compatible or else the feature will not work.
▪
▪ Matrix: make sure the PoE option on the TPS port is enabled (which is the default setting) via LDC in
the port properties window; see
section.
INFO: PoE-compatible and not compatible devices can be connected simultaneously as the feature can
be set individually on each port.
