WARNING Although Microchip Technology Inc. has taken steps to protect your touch screen controller from transient voltage, it is important to make all grounding, communication and touch screen connections to the controller and touch screen. This must be done before powering on your computer, video monitor or touch screen controller. Failure to follow this procedure may result in damage to your controller and/or communication port. If you believe that your application will require additional static protection, it is up to you to determine the appropriate static protection needed to protect your electronics from transient voltage. Failure to take the necessary precautions may result in damage to your controller. Microchip does not warranty the Microchip controller board against transient static discharge damage.  2011 Microchip Technology Inc.

Connections FIGURE 2-1: 2.1 CONNECTIONS – OVERVIEW MOUNTING Two static ground mounting holes (0.122" diameter) are provided. Take special care to insulate the controller from system and from EMI and RFI generating components of the display. Use conductive 4-40 stand-offs or ground-lead wires terminated to the grounded system enclosure or PC board to insure proper static protection and grounding. STANDOFFS MUST NOT TOUCH ANY PORTION OF THE CIRCUIT. Position the controller in a location that minimizes bending or creasing of the touch screen overlay connection tail. Wear to the tail, printed traces, or tail header will negatively impact touch screen performance. 2.2 POWER Power to the AR1100 Touch Screen Controller Board is provided by the H1 communication connector as seen in Figure 2-2. In USB Communication mode, power can be derived from the USB bus. In RS-232 mode – regulated power (3.3V – 5.0V) is provided from an external source. Check connections before applying power to the controller as reversing polarity WILL damage the board. FIGURE 2-2: POWER  2011 Microchip Technology Inc. DS41604A-page 13 mTouch™ AR1100 User’s Guide WARNING SUPPLYING POWER FROM TWO DIFFERENT POWER SOURCES WILL PERMANENTLY DESTROY YOUR CONTROLLER, YOUR COMPUTER, OR YOUR MONITOR. If the Microchip AR1100 Touch Screen Controller Board is installed into a monitor application where the end user will decide to use USB communication or RS-232 communication, the board must be powered internally. Because the board cannot be supplied with power from USB and internal 5V, it is recommended that the power (pin 1) contact be removed from the USB socket to insure that multiple power source connections are not permitted. 2.3 COMMUNICATION The AR1100 Touch Screen Controller Board will automatically detect and configure itself for the active communication protocol – RS-232 or USB HID. The controller will default to RS-232 communication until USB activity is detected. Once the active communication mode is determined, the inactive mode is decommissioned to minimize power consumption. The active communication will remain in effect until power is removed from the controller. 2.3.1 RS-232 Microchip cable harness p/n: C72-080S1F-09XDXF is a standard 6' long, round shielded cable terminated by a DB-9 female connector and an 8-position single-row socket.

Touch Screen Selection The 4 and 8-wire touch screens are typically produced with higher resistance transparent conductive film (ITO Indium Tin Oxide) than 5-wire touch screens. Most often, touch screen resistance falls within 100-400 Ohm per square. Because 4 and 8-wire touch screens typically have a higher resistance than 5-wire sensors, you will find most battery-powered applications using this technology. You will also find that 4 and 8-wire touch screens are more linear than 5-wire ones. The 5-wire touch screens are typically more mechanically durable (top sheet does not need to be linear) and are less affected by environmental variation. 5-wire touch screens come in a wide variety of sheet resistance. In some cases, because of the 5-wire construction, the resistance may be lower than the 50 Ohm specification. While these touch screens require more power to drive them, this does not imply poor quality. Once resistance drops below an optimum level, so does the resolution. In contrast, as resistance increases, depending upon the construction, contact resistance begins to negatively affect the touch screen’s performance. The negative effect of a high or low resistance touch screen can be managed by properly implementing the correct circuit. It should be understood that extremes in either direction will negatively influence the performance of any efficient circuit design. In order to maximize efficiency and performance, a higher resistance, linear, environmentally stable touch screen is recommended. Your product design requirements will help you identify the touch screen technology and construction that will best suit your application.
