(100 m or longer), or if you are experiencing occasional video dropouts, even if the
UTP cable is not that long! If your receiver can support this mode, Long Reach
provides the best chance to resolve most issues such as ground-loops,
electromagnetic or static discharge interference, or if you are using lower quality
UTP cables, is to put the link in Long Reach mode if the receiver supports it.
However, you must be aware that in this mode the max resolution supported is
1080p @ 60 Hz 8-bit (24 bit total) color. Deep color and 4K (UHD) video is not
supported in LR mode.
 Power Management – When it is selected, the UHBX-8X device will check for the
presence of source video and sink HPD (whether there is a display connected and if
Miscellaneous
it it is turned on). If neither source video nor HPD is
detected, the HDBaseT extender module at the output
will be placed in low power mode. If you are not
extending IR or RS-232 to the remotes, we recommend
that you enable Power Management. This will ensure that when there is no video
from the source, or if the display is turned off, the HDBaseT chipsets will be placed
in low power mode. The reason you may not want to enable this mode when
extending RS-232 or IR, is because when the link is in low power, baud rates higher
than 9600 or IR signals with modulation can not be reliably extended.
The default state is Power Management off.
2.4. Status
The UHBX-8X GUI provides real time status
indication of the HDBaseT links and the current
RS232 output channel selection and baud rate
setting for that channel.
When the Link LED is flashing, it is indicating the HDBaseT extender module at the
specified output is in Low Power mode due to either +5V video source or HPD sink
LCD being not detected.
