In addition to USB3, the kit extends RS232 signals and FSYNC video signal (for camera frame synchronization). The EXT3-U3-T transmitter unit converts the USB3 host side signal into a CATx signal format based on HDBaseT.USB. The EXT3-U3-R receiver unit converts the CATx signal back into a USB3 device side signal and functions as a USB hub for up to 3 devices. EXT3-U3-T/R operates seamlessly as a plug&play device with no need for any prior configuration. It supports a wide variety of USB peripheral devices supporting all USB transaction modes including interrupt, bulk and isochronous and is especially suitable for high throughput video streaming USB devices such as cameras and capture devices. EXT3-U3-T/R uses power delivery over the CATx cable requiring only one side to facilitate a power source. EXT3-U3-T/R provides exceptional quality, advanced and user-friendly operation, and flexible control: · Comprehensive USB Extender Plug & play USB extender kit for providing extended-reach CAT signals and 2-way power over twisted pair copper infrastructures. A local USB host is auto-connected to remote-connected USB devices employing either interrupt, bulk or isochronous USB standard data transfer communication. · Flexible USB Connectivity Wide Variety of USB peripheral devices can be extended including cameras, touch screens, smart boards, hard drives, game controllers, audio devices, printers, scanners, or HID (Human Interface Devices) devices such as a mouse or keyboard. Dual role and OTG (On-The-Go) devices such as smart phones and tablets, connected either to a transmitterside USB host port or receiver-side USB device port, can communication with a remote host or peripheral pairing device. · Remote USB Charging Fast USB charging of peripheral devices when the receiver is EXT3-U3-T/R Introduction 2 Kramer Electronics Ltd. powered by the external power supply, or standard USB charging when the receiver is powered by the transmitter via CAT. · Bidirectional RS-232 Extension Serial interface data flows in both directions, allowing data transmission and device control. · Cost-Effective Maintenance Status LED indicators facilitate easy local maintenance and troubleshooting. Typical Applications EXT3-U3-T/R is ideal for the following typical applications: USB Camera deployment in meeting spaces and lecture halls Extending Video Over USB formats like UVC or DisplayLink Smartphone docking applications USB storage devices remote deployment EXT3-U3-T/R Introduction 3 Kramer Electronics Ltd.
