Universal Switcher Concept
UMX-HDMI-140 is a universal audio/video switcher with analog/digital conversion and audio embedding
functions. 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 the 5-pole Phoenix connectors. 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 interfaces.

Port Diagram
The device has four video input ports to receive analog video (VGA, DVI-A) and digital video (HDMI, DP,
DVI-D) signals. The analog signals are converted to digital. A 5:1 digital audio/video switch decides which
signal is routed toward the HDMI output port. The device also has two analog audio input ports (3.5mm
Jack, 5-pole Phoenix). The analog signals are converted to digital ones. The user can choose which audio
signal is transmitted on the HDMI output port: one from the analog audio sources or the original embedded
audio from the HDMI / DP / DVI-D ports.
INFO:
The DVI-D input accepts HDMI signal with embedded audio as well.
Besides, the switcher has four different interfaces to control the unit itself or third-party devices: infrared
(input and output), RS-232, Ethernet, and GPIO.
