Electrical Connections
HDMI Input and Output Ports
The matrix switchers are assembled with standard 19-pole HDMI
connectors for inputs and outputs. The outputs are able to supply 500
mA current on DDC +5V output (pin 18) which is sufficient to supply
power to certain devices (e.g. DA2-HDMI-4K-Plus-A).
Symmetrical Analog Stereo Audio
5-pole Phoenix connector is used for balanced analog audio (line in/
out). Some I/O boards use this connector as a configurable input
or output. Unbalanced audio signals can be connected as well. For
asymmetrical output, connect only + and ground. For asymmetrical
input c and ground to the source and connect – to the ground.
