DIP Switch Configuration
HPD Mode
HPD (Hot-Plug Detect) is an HDMI feature that senses if the HDMI cable is disconnected
from the source or sink device. Once this occurs, the HDMI link is re-initialized if
necessary. The 4K Ultra HD HDBaseT Extender w/ RS-232, 2-way IR and POL
allows you to control the way HPD is handled.
