The IPLinx IPEX5001/5002 transmits HDMI video and audio over a gigabit IP network using JPEG2000 encoding. The IPEX5001 supports video signals up to 4K at 60 Hz 4:2:0 with HDCP 2.2 and 7.1 multichannel audio. An analog audio input port embeds the audio with the video content, such as a DVI video source. The IPEX5001/5002 supports PoE and can be powered remotely by compatible power source equipment, such as a PoE Ethernet switch, eliminating the need for a nearby power outlet. The RS232 port relays commands from the IP controller and operates in a pass-through capacity to control a third party device such as a projector. The USB connection passes keyboard and mouse signals from the IPEX5002 decoder to the IPEX5001.
