Introduction Congratulations on your purchase of a NextWindow 2700 Touch Overlay. This product turns a large-format display, such as a plasma or LCD, into an interactive display. You can control a computer application simply by touching the screen. The 2700 can be connected to the computer via a serial or USB cable, thus providing maximum versatility. The USB option is HID compliant, providing true plug-and-play operation, just like a USB mouse.
Capabilities The following table shows the touch functionality provided by a NextWindow 2700 with different operating systems.
Unpacking the Unit Unpack the unit, taking care not to damage the surfaces. Check the product for any signs of damage in transit. Installation Requirements Once you have unpacked the unit, make sure you have the following: The display monitor that you are going to mount the touch overlay onto. The computer that runs your software application, including the cable that connects the computer to the display screen. The USB or serial cable to connect the touch overlay to the computer.
Parts of the Touch Overlay The 2700 Touch Overlay consists of aluminium extrusions joined at the corners with cast zinc corner pieces. The electronics and connection sockets are housed in the top bar of the overlay. Soft padding is provided to protect your monitor when the overlay is fitted to it. The overlay is secured with straps, which allow flexibility for fitting to different manufacturers’ monitors.
Installation Instructions Different methods are used for different applications: For pedestal-mounted screens, the touch overlay can be fitted to the screen where it stands. For wall-mounted screens, the screen may need to be removed from the wall first and then fitted to the touch overlay. The installation normally requires two people. Preparation 1. Make sure the monitor is stable and situated so that you can walk all around it. 2.
Spacers The 2700 overlay comes with suitable spacers for the monitor that it was ordered for. The spacers support the weight of the overlay and also provide for air circulation. All 2700 overlays have one spacer as standard, but up to two extra spacers are required for certain monitors.
Installing on a Pedestal-Mounted Monitor 1. Stand the touch overlay on its bottom edge and carefully flip the top securing straps (the shorter ones) over to the front of the overlay. 2. Lift the overlay onto the monitor at an angle as shown below and locate the top edge first. 3. Lower the bottom edge of the overlay into place. 4. While holding the overlay in place so that it cannot fall off, attach the straps at the rear and pull tight to secure the overlay. Note: You need two hands to fasten the straps.
3-bar slider Pull strap tight 5. Tuck the loose end of the strap into the 3-bar slider provided.
Installing on a Wall-Mounted Monitor To install the touch overlay on a wall-mounted monitor, first remove the monitor from the wall, and then place it onto the overlay. This will require two people. Lower the monitor onto the touch overlay, top edge first. Make sure the top is a snug fit, then lower the bottom onto the overlay. Tighten the straps firmly around the display screen, making sure that they do not cover any connections or air vents.
USB Installation USB installations require no special software; the touch overlay communicates directly with the computer’s operating system via the USB interface, just like a USB mouse. Connect the USB cable from the touch overlay to the computer. Velcro cable tie You can use the Velcro cable-tie provided in order to fasten the USB cable at the back of the monitor.
For USB communications, you do not need to install any software. However, an optional USB Configuration program is provided that allows you to change the default operating parameters if required (see page 16). Before operating the touch screen, you need to calibrate it.
