The CAT5 extender includes Video, analog audio, USB, RS232, and IR CAT5 extender design for extending and distributing all signals over one CAT5 up to 150 meters, with local HD monitor output.  It provides superior video quality up to 1920 x 1200 resolutions, and using cost effective Cat5e cable, instead of separate cables, for an easy, neater and reliable installation. The local and remote units can be connected together for a Point-to-Point connection via CAT5e/6 cable or a Point-to-Many connection via a managed network switch.  Any combination of transmitters and receivers can be used, easy to increase more sources or monitor for a flexible application.   It is optimized for applications at broadcasting system, multimedia display and multi-data sharing, digital signage, home network integration, and industrial control, hospital, education, security, matrix network system and system control over RS232 and equipment control over IR.Extend and distribute video signal with bi-directional RS232, USB signal, IR and analog audio signals over LAN. *** Video/Audio     * Supports resolutions up to 1920 x 1200 (WUXGA) 32bpp@ 60 Hz     * Transmitter unit built in VGA local loop output.     * Built in Bi-Directional analog audio transmission (only in point to point mode). *** USB / Serial / IR     * Receiver unit with 4 ports USB devices (1 port USB 1.1 & 3 Port USB 2.0), to extend USB peripheral devices, such as flash disk, hard disk, keyboard, mouse, etc.     * Built in RS232 distribution function, to send RS232 signal from one TX to multiple RX.      * Supports 2-way RS232 commands at baud rate 115200 (control software on a PC, or other automated control system hardware) to control devices attached to the matrix using RS232.
