Description
UMX-HDMI-140 switches universal 4K video and audio to a HDMI
output port. This device was designed for digital and analog video
and audio signals: VGA, DVI, HDMI 1.4 and DP 1.1 with analog stereo
audio from local inputs or embedded 7.1 HBR audio. The unit can also
handle HDCP encryption. Analog signals (both audio and video) are
converted into digital format. Using the factory, custom or transparent
connector. Advanced EDID Management forces the required resolution
system requirements.
The Advanced Control feature pack includes functions which help to
system automation challenges. In small to mid-size systems, these
automation features can help to dismiss an additional control
processor box, thus lowering integration time and costs.

Automatic Input Selection - Example
The Concept
If there is no other source connected to the switcher, but the Laptop, VGA input will be automatically switched
to the HDMI output. If the Laptop and the PC are also connected to the switcher, DVI-D input will be switched
to the HDMI output. If the Blu-ray player is connected on the HDMI input, and later the MacBook is connected
on the DP input of the switcher, it will be switched to the HDMI output – independently of the presence of
other video signals.

Event Manager Mode
Third-party devices can be controlled from Event Manager in this mode. ASCII characters and binary data in
hexadecimal format can be used in this case.
The following ways are available for controlling the devices:
▪The System controller sends messages over the LAN port of the Switcher to the given port number. The
Switcher converts the incoming TCP messages to RS-232 commands and transmits over the local
RS-232 port to the HDTV. The local RS-232 port has to be set to Command Injection mode. In this case
the direction of the communication is bi-directional between the Switcher and the System controller,
so the answer of the HDTV is received by the System controller.
▪The Switcher sends a "power on" message to the HDTV via the RS-232 port if signal is received on the
DVI-D input. In this case the RS-232 port has to be set to Event Manager mode and an event has to be
created where the condition is "signal is received on I4" and the action is "send a message on RS-232
port". Find a detailed example for the serial message sending in the Event Creating - Example section.

IR Signal Transmission - Example
The Concept
An IR detector is attached to the Infrared input port of the switcher and IR signals are sent by the Remote
HDTV).
UMX-HDMI-140 switcher's input can be routed by the remote controller the following way:
Step 1. Make the Switcher learn the IR codes of the desired remote control buttons, see the Learning IR Code
(hash) section.
Step 2. Arrange the events in Event Manager; if the set IR code is received from the IR input (condition), then
switch the input source between the Blu-ray player and the MacBook (action) in the Switcher. In this case
you can control the HDTV via the Switcher remotely. See the details about the Event Manager settings
in the Event Manager section.
Advanced IR functionality
UMX-HDMI-140-Plus can send Little-endian pronto hex IR codes on its IR output port.
It is possible in the following ways:
▪Sending pronto hex codes (Little-endian
format) section)
▪Sending pronto hex codes (Little-endian format) and Event
