Universal Switcher Concept
UMX-HDMI-140 is an universal audio/video switcher with analog/digital converter and audio
embedder function. The device receives analog (VGA, DVI-A) and digital (DP, HDMI, DVI-D)
video signals and transmits HDMI. Analog audio signals can be received via the 3.5” TRS
(jack) and also the 5-pole Phoenix connector. The device can be controlled via Ethernet,
RS-232 or Infrared and is able to control third-party devices via the RS-232, Ethernet, Infrared,
and GPIO interfaces.

Powering on the devices is recommended to do as the nal step during the installation.
HDMI / DisplayPort cables.
Optionally for audio extension: connect the audio source (e.g. VGA laptop)
to the audio input port by an audio cable.
Connect the sink (e.g. HDTV) to the HDMI output port by HDMI cable.
Optionally for RS-232 extension: connect a controller/controlled device
(e.g. HDTV) to the RS-232 port.
Optionally for Infrared extension:
Connect the IR emitter to the IR OUT port of the switcher, and/or
Connect the IR detector to the IR IN port of the switcher.
Optionally connect the switcher to a LAN network in order to control
the device.
Optionally connect a controller/controlled device (e.g. relay box) to the
GPIO port.
Connect the power adaptor to the DC input of the switcher, then to the AC
power socket.
Mounting
To mount the switcher Lightware supplies optional accessories for different usage. There are
two kinds of mounting kits with similar xing method. The switcher has two mounting holes with
inner thread on the bottom side. Fasten the device by the screws enclosed with the accessory.
Under-desk double mounting kit 1U high rack shelf
The Under-desk double mounting kit makes easy to mount a single device on any at surface,
e.g. furniture. 1U high rack shelf provides mounting holes for fastening two half-rack or four
quarter-rack sized units. Pocket-sized devices can also be fastened on the shelf. To order
mounting accessories please contact [email protected].
Using different (e.g. longer) screws may cause damage to the device.
The switcher is half-rack sized.
Locking DC plug
Twist 90° clockwise to lock.
