    How to: -Keep USB touchscreen on after you turn it off

    DISCLAIMER: - I ACCEPT NO RESPONSIBLILTY FOR INJURY LOSS USING ANY INFORMATION SEEN BELOW.



    It seems the Xenarc touchscreen isnt self powered and only comes on after the screen itself has had power given to it.

    i have my screen turn off HARD when i pull my keyout, but my computer stays on until the opus turns it off softely, so the computer thinks ive pulled the touchscreen usb out. WHen it comes back on i get a Duuuuu-daaaaaa as if ive pulled it back in again (which in effect i have as i turn my screen on) and it messes up any visulisation i have running)

    SO to solve this, you need to do what i have done below. Seperate the USB touchscreen from the Xenarcs 20 Pin lead.


    The following assumes you know abit about electronics and have disassembled a xenarc/gain beforehand

    1# Find a spare longish USB lead with a male end on it.

    2# Cut and strip back the wire to expose the inner cables Positive Negative and the two signal wires.

    3#Before you unplug the cable on the back on the xenarc linking the USB touchscreen board to the xenarc 20pin connector you may want to check the continuity of which connect is which and where it goes at the end of the USB plug. Note, you will not get a electricity flow through the V+ pin on the USB controller and the USB plug as that is in effect 'blocked' until you turn the screen on (which is why i am doing this)


    4# Unplug the cable that links the xenarcs 20pin board to the USB controller board. Notice there are 5 PINS on the controller board but only 4 on the plug that plugs into it. WHen you plug the connector back it ensure it is biased more towards one side than the other. (see pic at the bottom)

    5# Either cut the original cable linking the USB touch board with the Xenarc's 20pin board or find the same connector from elsewhere (like i did) and solder it up based on your findings in #3

    6# notice the colours of the USB leads and the little connector. These colours and positions were correct for my situation but i cannot garentee they will be the same for you. They should be if all colours are followed in USB leads but i suggest you check and double check it with a continuity tester (multimeter) first




    7# Individually insulate them up then insualte the whole lot to ensure a good strong join in the cable (fragile connectiond under there)



    8# triple check all connections and connect to USB controller. Notice how it is more towards one side of the connector than the other, leaving one pin not used it the recieving connector block.



    9# Fire it up (not literally we hope) and test with fingers crossed

    10# Admire your work






    I hope some of you will find this useful

    good luck

    If installing the Xenarc after a Lilliput (or any monitor) change the refresh rate (in the control panel) to 60Herts FIRST.
    It was an *itch to do this after installing the Xenarc.

    When taking apart your xenarc, be very careful if you remove the touchscreen controller. On one side there is a plug for a flat 4 pin plug for the touchscreen overlay itself, if you plug this in upside down, the touchscreen will work, but the orientation will be reversed. On the opposite side is a 5 pin plug that takes a 4 pin cable. This is can be a problem, make sure you plug the 4 pin cable into the touchscreen controller so the yellow wire is on the pin at the edge of the controller. The fifth pin is not used. Plugging this cable in wrong may damage the touchscreen controller.

    When installing the touchscreen drivers, make sure you run the setup.exe, don't try to install the drivers directly from the CD, the touchscreen will be detected, but it will not work.

    If you do break stuff after taking your screen, xenarc is pretty good about selling you parts. You can get them by contacting someone in the sales department at xenarc. These prices may not be accurate at the time you read this.
    TouchScreen overlay: $50
    TouchScreen Controller: $50
    Backlight Inverter: $50
