Use these points as an initial guide. NCG can verify the source, display, cable route, control, audio, and power requirements before procurement.
Request a Signal-Path Review- The HDMI source and destination are separated by up to 70 metres
- A direct Cat6/6a cable route can connect the transmitter and receiver
- The complete source-to-display path supports the required HDMI and HDCP standards
- A local HDMI loop output is useful beside the source equipment
- Bi-directional IR or optical audio output is required
- Powering the transmitter or receiver from one end simplifies installation
Cable type and termination, endpoint compatibility, EDID, HDCP, grounding, surge protection, and installation conditions should be confirmed for each project.
