AT5 Audio Video Splitter and Receiver 3 2 Receiver Several receiver types are available URA x All Receivers have a single COMPENSATION potentiometer pot adjustment to recover high frequency signal loss for long runs of the cable The Model URA X2 has 2 identical VGA outputs and 2 Audio outputs It acts as if a standard URA was followed by a video and audio splitter The URA VOL provides volume level adjustment section 3 2 1 3 2 1 Adjusting the video quality for long cable runs Please refer to Figure 2 4 for the location of the compensation pot Turning the pot CW increases the compensation Use a small screwdriver and starting from CCW slowly turn the pot CW until the image is perfectly clear Fully CCW corresponds to no compensation recommended for lengths of 100 ft or less and fully CW corresponds to 1000 feet Be careful not to over compensate the video image The video quality at the remote station depends on 1 the length of the CATS cable 2 video resolution setting and 3 refresh rate setting In general at low and mid resolutions excellent image reproduction is provided at up to 1000 feet At high resolution and refresh rates perfect image reproduction can be achieved at shorter distances see table 3 1 below Using longer cables or higher resolution rates will still produce an image but the reproduction quality will be reduced Refresh Rate Table 3 1 60 Hz 75 Hz 85 Hz 800x600 1000 ft 1000ft 100

J45 connectors Both UTP and STP shielded cables can be used In addition you can use Cat5 Se 6 or higher However for runs of over 250 feet HRT recommends using Skew free or Zero skew Cat5 cables for best performance The senders also have local buffered loop thru outputs for the VGA and audio for connection to local monitor or expansion At the receiving remote end a receiver Model URA sold separately is used to convert the UTP signal back to VGA and audio These products are housed in compact shielded enclosures and include connectors for a local monitor and speakers as well as multiple RJ45 connectors for connection to remote monitors Included with the devices are a small power supply The senders also come with short video and audio cables for connection to the PC s VGA and sound card s outputs The RJ45 outputs on the Splitters can drive CATS LAN cables to 1000 feet 305 meters with little to no degradation of video quality depending on resolution of the VGA signal see table 3 2 The receiver can compensate for signal losses in long cable runs o MA Compact CAT5 Audio Video Splitters and Receiver 1 2 Features e Support for local monitor and speaker at sending end e Handles resolutions up to 1600x1280 at any refresh rate e Rugged Reliable Compact size e No software required e Drive standard CATS cables to 1000 feet e Transmit audio and video signals on one cable e Easily expand Splitters

12. ssion over twisted pair offers good immunity to EMI coupled noise from other external sources However a strong electromagnetic noise field can cause instability in the signal Usual sources are high power AC lines or data and or control cables that run adjacent to and parallel with a substantial length of the CATS cable To eliminate this either place a distance between the CATS cables from the splitter and the interfering source or use shielded twisted pair STP CATS cables 4 The PC does not recognize a Plug and Play monitor If the PC s Operating System is setup to detect a plug and play monitor usually in Display Properties Advanced Settings it may have trouble finding a monitor if no local monitor is hooked up to the splitter Only the ID information of the local monitor is passed to the PC If the PC does not produce an image due to this either connect a monitor to the local VGA output port or disable the plug and play monitor detection in the PC s operating system o Compact CAT5 Audio Video Splitter and Receiver 5 Poor audio quality at the receiving end Only use powered speakers with the splitter and receivers It is also good practice to set the audio level volume output of the PC about 1 2 to 2 3 from the maximum and use the volume knob of the speakers to adjust the volume to the desired level A low volume signal output from the PC reduces the signal to noise S N ratio whereas too high output amplitude can
