Anleitung Zusammenfassung


2011 Please read this manual first for correct installation and operation. This manual should be retained for future reference. The information in this manual was current when published. The manufacturer reserves the right to revise and improve its products. All specifications are therefore subject to change without notice. PRECAUTIONS 1. Do not install the EHA-SRX near electric or magnetic fields. Install the EHA-SRX away from TV/radio transmitters, magnets, electric motors, transformers and audio speakers since the electromagnetic fields generated from these devices may distort the video image. 2. Never disassemble the EHA-SRX beyond the recommendations in this manual nor introduce materials other than those recommended herein. Improper disassembly or introduction of corrosive materials may result in equipment failure or other damage. 3. Keep the power cord away from water and other liquids and never touch the power cord with wet hands. Touching a wet power cord with hands or touching the power cord with wet hands may result in electric shock. 4. Never install the EHA-SRX in areas exposed to water, oil or gas. Water, oil or gas may result in equipment failure, electric shock or, in extreme cases, fire. 5. Do not operate the camera beyond the specified temperature, humidity or power source ratings. Use the camera at temperatures within 0. ~ 50. (32.~122.) and humidity between 20~80%. The input power source is 12VDC. 1. INTRODUCTION The EHA-SRX accepts the HD-CCTV digital video signal from an HD-SDI compliant HD-CCTV camera, and coverts the signal for presentation on the HDMI input of an HD TV or monitor. The converter supports HD-SDI video signals compliant with the SMPTE 292M, 296M standards, at data rates up to 1.485Gb/s. With integrated cable equalizer technology, the EHA-SRX is capable of receiving HD-SDI digital video at up to 1920 x 1080 resolution over 75. coaxial cable. This provides a complete solution for the transmission and display of both interlaced and progressive scan HD-SDI digital video from coaxial cable-based HD-CCTV cameras. 2. FEATURES . Accepts HD-CCTV high-definition HD-SDI digital video at 720p/60, 1080i/60 and 1080p/30 formats/ frame rates . Processes HD-SDI standard SMPTE292M, 296M at 1.485Gb/s data rate . Provides standard HDMI output for HD TV monitor display . Integrated cable equalizer for long distance video transmission without loss of quality . Capable of receiving HD-CCTV digital video over 75. coaxial cable at distances over 100M (depending on cable type) . High quality digital video and audio transmission with near zero latency 3.

CABLE REQUIREMENTS FOR BNC CONNECTOR 7.1 Cable Types The EHA-SRX allows a total signal attenuation of up to 43.5 dB along the cable between devices. The actual maximum cable length depends on the attenuation characteristic of the particular cable used. Generally speaking, the better the cable quality, the lower the signal attenuation, thus the longer the distance the HD-CCTV video signal can be carried. The following table gives examples of different cable types, losses and the distances that can be achieved. These are only examples and the actual distance is determined by the attenuation characteristic of the cable in your application. The table below gives an orientation for achievable cable distances: Cable Type Attenuation in dB at 1 GHz per 100 m / 328 ft Max. Cable distance in m ft RG-59 24 ~ 40 * 70 ~ 160 230~520 RG-6 15 ~ 35 * 100 ~ 190 330~620 RG-11, CATV-lowloss cables 8 ~ 16 * 180 ~< 250 590~<820 * Low quality cable may have higher attenuation 7.2 Cable Installation Please make sure, that the coaxial cable is not squeezed at any position. Also the max. bending radius defined by the cable manufacturer should be considered. General rule: maximum bending radius = 10 x outer cable diameter Bending creates pressure on the center conductor, causing it to move through the dielectric toward the inside of the bend. This affects impedance and return loss and reduces the maximum possible cable length. Please try to avoid any BNC...
