HDBaseT is a global standard of the transmission of high-denion video and audio, Ethernet, controls, USB
and up to 100W of power over a single cable, for up to 100M/328.
The (Ref. SMX250-H) is fully compliant with the HDBaseT Specicaons.
Equipped with HDBaseT receivers and transmiers, the is able to input video, embedded
audio, Ethernet pass-through and manage a Power over Ethernet feed (30W) and to output video, embedded
audio, Ethernet, plus a bidireconal Serial connecon and a IR connecon.
The bidireconal serial and the IR connecon are output via the 5-pin MCO connectors associated to the
HDBaseT port.
Based on the HDBaseT specicaons of the HDBaseT Alliance, the is compable with the
list of HDBaseT products referenced by the HDBaseT alliance. The full list of available products are listed at

In case of issue with your installaon, the HDBaseT alliance has released a troubleshoot guide.

HDBaseT runs on a regular cable (Cat5E or above), so any best pracces regarding Ethernet installaons also
apply here. Cable performance is dened by the quality of the cable, the distance of the connecon, the
handling of the cable and the video resoluon expected. A rule of thumb is that the higher resoluon, the
beer the cable should be. The same goes for distance.
The cabling infrastructure in any project is likely to be around for a long me -it should last longer than
any other component in the network, and choice of cable should take into consideraon new applicaons,
addional users and potenal expansions of the whole systems.

There is a reason that the wires are twisted: it cancels out electromagnec interference (EMI) from external
sources and crosstalk from neighboring conductors. When terminang the cable, make sure not to untwist
more than half-an-inch (and preferable a quarter-of-an-inch) form the point of terminaon, and remove as
lile of the sheath as possible.
LAN cable are fairly resilient. Yet, any rough handling, such as ght e wraps, clamping or stapling can
damage the cable, compromising performance or event prevenng signal transmission. Tie cables loosely
with appropriate cable wraps, and make sure to use appropriate cable support systems when too many
cables are involved, such as trays, carriers or J-hooks. If pulling cables is necessary, make sure not to pull
too hard because that also may cause pairs to untwist and degrade performance. Cable physical protecon
safeguards the integrity of data transmission.
Another important issue for cable integrity is the bend radius. Bend radius is the inside curve of the cable
during and agter installaon. It is best to keep the minimum bend radius at least at four mes the diameter
of the cable – that means that the cable should not be bent below that radius, so as not to damage it and
compromise signal transmission. Overbending may lossent or otherwise modify the wire twisng and increase
suscepbility to external noise and near-end crosstalk within the cable.
