UHBX-R-WP
4.2 LED Indicators
The front panel of the wall plate contains LEDs that show the state of
operation.
Figure 5 – LED Indicators
POWER Used as power indicator. Comes on after the wall plate successfully
negotiates PoH and gets power from the PSE sender (or power inserter).
If it is lit dimly (or blinking) , it means that PoH function is working but
there is some sort of other malfunction on the board such as over
temperature (it will go to low power mode and automatically recover
when temperature is back to acceptable range), or HDBaseT logic circuit
is experiencing problems.
VIDEO Displays Video Status. Off = No Video being received, Blinking = Video
without HDCP is being received, Solid ON = Video with HDCP is received
LINK Solid on means the HDBaseT input is connected to and communicating
with the up-stream sender. Blinking means Link has been established but
the unit is in low power mode. Off means the HDBaseT link to the sender
is not working (check cable length, cable quality, connection integrity).
4.3 More on RS-232 Serial Connection and Operation
If required, plug DB9 null modem RS232 cable from the Receiver to the
device being controlled (such as a projector or switcher). Pin out of the Male
RS232 connector on the sender is shown below
The UHBX-R-WP supports bidirectional RS232 and communicates with a
host through its HDBaseT input at a baud rate ranging from 110 thru 115200.
4.3.1 Power Management and RS-232 Operation
By default “Power Management” is turned on. This means that if there is no
video being extended, after some time, the system will place it’s HDBaseT
link in low power mode (and consume only about 10% of normal power). The
system will wait for HDMI source signal to become active (and for HPD from
connected TV to be asserted) and will wake up on its own.
A characteristic of HDBaseT chipset is that in low power mode it only
supports RS-232 up to 9600 baud. So if power mgmt is active (default) and
