This unit is part of a large HDTV video distribution ECO system with up to 100 independent HDTV 1080P channels. Works with additional Calrad 40-101T Gen3 (QAM) Transmitters and with additional Calrad 40-101R (QAM) Receivers. Calrad has developed a simple expandable 1080p video delivery system with control signals over coax, Cat5e or Cat6 cabling with distances up to over 2,000 ft.. The technology can also support existing legacy wiring such as standard shielded audio, composite, component, HDMI cables using specific inline adapters for each cable type. Once connected the HDMI transmitter and receiver can connect a source to a display that can be totally independent from each other or multiple 40-101 units can be used providing signals upstream and downstream from each other, bidirectionally over the same wiring. Each transmitter and receiver can be IR controlled individually from a 3rd party automation control system or Calrad's Xcontrolled automation system or by a local individual IR receiver from a local remote (Included). Easy setup, set transmitters and receivers to independent channels manually on the front panel using the up/down push buttons or use a automated control system to maximize the flexibility using 100 channels between transmitters and receiver. Supports CATV digital splitters and amplifiers.
