3. 2 STP shielding RJ45 connector with STP cable connection ground cable folded Must touch the Metal Housing TU R STP RJ45 connector Metal Housing If your RJ45 connector is plastic housing unshielded then the cable connection must do the following 1 The ground cable must pull out around 5 10cm length to connect with VGA Extender s ground screw for grounding 5 10 cm ground cable RJ45 connector Plastic Housing 2 Make the ground cable connect to ground screw then plug RJ45 connector CAT5 VGA Extender ITEM NO VB C5 The VGA Extender allows VGA video signals to be transmitted up to 135 meters via 4 paris CAT5 STP or UTP cable Used in pairs the VGA Extender is used in home or commercial applications as a smart fast and cost effective eliminates costly and bulky VGA cable allowing VGA monitors to be connected extended distances from the PC via standard twisted pair cable Ideal for classrooms video distribution lecture halls retail kiosks video information displays overhead projector systems PC training systems and tradeshows PC demo systems Features 1 VGA connector to RJ45 female Including 2 units as transmitter and receiver Up to 135 meters via standard 4 pairs CAT5 STP or UTP cable instead of VGA cable Built in Dip switch for compatible with all monitors when using CAT5 UTP cable Supports up to 1280x1024 pixels Passive device not support VGA DDC protocol Perfect
4. e VGA equipment or the connection may be picking up some external interference from a nearby power transformer A solution is to change the cable to use STP cable 5 Ghosting Ghosting is characterized by a second video image being received after the main image resulting in a double image This is usually caused by the UTP cable connection itself poor crimping untwisted pairs some of the twisted pairs may be longer than others poor quality cable or the impendence mismatch at the cable In these cases the best way is to replace the existing cable with a new one 6 Wrong colors If the wrong colors appear in an image for example blue appears where green should appear the problem may be caused by poor crimp at RJ45 connector or wrong pin connection Please check the all connections and verify the pin configuration of the cable between CPU and the monitor to ensure that the correct pin configuration is respected Noted 1 The maximum distances supported by the VGA Extender are dependent on the type of twisted pair cable and image resolution of the PC s VGA interface Make sure that the maximum recommended operational distances have not been exceeded 2 All wiring is straight through twisted pair cable not being used for other LAN or telephone equipment 3 Do not connect the VGA Extender to a telecommunication outlet wired to unrelated equipment Installation View 135M Max VGA Display Equipment 2 Panel View
5. p switch of receiver unit the solution is to replace the cable for STP cable 7 Improper setting may cause no picture display 8 After properly setting you could adjust the contrast and brightness of the monitor for the best picture quality Troubleshooting at picture problem 1 Picture disappear intermittence or no picture display Please adjust the Dip switch setting or change the vertical SYNC frequency of the VGA display card DVR 2 Display not syncing up properly There are some certain models or brands of monitors with very high demand at sync sensitive and the Dip switch setting may not do properly compensation Please use STP shielding twisted pair cable to instead of UTP unshielded twisted pair cable 3 Blur picture or Loss of image details This may occur as the length of twisted pair cable increases due to the effects of attenuations Please change active type of VGA extender which built in amplifier function to improve the picture or try to adjust the contrast and brightness of the monitor If the application operates adequately at a lower resolution i e 800x 600 instead of 1024 x768 then setting the monitor to a lower resolution will help improve the image Please note the higher dip switch setting for sync compensation may cause more video signal loss or no picture 4 Flutter Flutter occurs when the background fluctuates between light and dark This status may be caused the grounding problem between th
