4.2. Port Diagram
The following figure describes the port diagram of the UMX-HDMI-140 series switcher:
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:
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.
Applied firmware package: v1.2.0 | LDC software: v2.4.1b7
