1. for the daisy chain Model URA XT it is important to set the cable type 23 vs 24 AWG that you are using because of the cumulative nature of the daisy chain e Inthe adjustment mode press and hold the SEL button for at least 3 seconds to enable the WIRE SIZE selection mode between 23 gauge wire and 24 gauge wire e The UP button is used to select 24 gauge wire The DOWN button is used to select 23 gauge wire e To exit the adjustment mode at any time press the SEL button the unit also has a built in timeout to exit this mode 3 4 Why Skew Adjustment UTP cables have 4 twisted pairs inside The Hall Research UVA URA video transmission on UTP uses 3 individual pairs for each color Red Green amp Blue w Local Video Screen UTP Cable Remote Video Screen Figure 6 skew mechanism explained As shown in the figure above a characteristic of Category 5 5e 6 cable is that the pairs of wires are twisted at different rates Therefore for a given length of Cat 6 cable the total length of any particular pair could be longer than other pairs in the same cable Since the signals travel along the length of each pair at a fixed speed the arrival times of signals will be skewed in a long cable those that have to travel farther arrive later and the corresponding color shifts to the right This is seen on the monitor as separation or lack of convergence in colors For example a vertical white line on the screen may loo2. first 4 1 Contacting Hall Research If you determine that the URA URA SKU or URA XT is malfunctioning do not attempt to repair the unit instead contact Hall Research Technical Support at 714 641 6607 Before you do make a record of the history of the problem We will be able to provide more efficient and accurate assistance if you have a complete description 4 2 Shipping and Packaging If you need to transport or ship your unit Package it carefully We recommend that you use the original container Before you ship the units back to Hall Research for repair or return contact us to get a Return Authorization RMA number Model URA URA SKU amp URA XT 4 3 Problem Solving FAQ 1 Fuzzy blurry or ghosting image at remote location If you have a stable image but it looks somewhat blurry edges are not sharp make sure that you have adjusted the receiver unit s HF compensation correctly In addition check the recommended table of max distance vs resolution to see that you have not exceeded the maximum recommended cable lengths If you still have a fuzzy image try reducing the refresh rate and or resolution of the video source Image exhibits steady or rolling horizontal color hum bars This is usually an indication of improper grounding at the sending end the receiving end or both Verify that the AC line is properly wired and that a protective ground green wire is established with NO potential dif
