无源底板的插槽由总线扩展槽组成。总线扩展槽可依据用户的实际应用选用扩展ISA总线、PC总线和PCI-E总线.PCIMG总线的多个插槽组成，扩展插槽的数量和位置根据需要有一定选择，但依据不同PCIMG总线规范版本各种总线在组合搭配上有要求，如PCIMG1.3版本总线不提供ISA总线支持，该板为四层结构，中间两层分别为地层和电源层，这种结构方式可以减弱板上逻辑信号的相互干扰和降低电源阻抗。底板可插接各种板卡，包括CPU卡、显示卡、控制卡、I/0卡等.

从技术原理角度来讲，触摸屏是一套透明的坐标定位系统，它是透明的，因此它通过材料科技来解决透明问题，像数字化仪、写字板、电梯开关，它们都不是触摸屏，其次它是坐标，手指摸哪就是哪，不需要二个动作，不像鼠标，是相对定位的一套系统，我们可以注意到，触摸屏软件都不需要光标，有光标反倒影响用户的注意力，因为光标是给相对定位的设备用的，相对定位的设备要移动到一个地方要知道身在何处，往哪个方向去，每时每刻还需要不停的给用户反馈当前的位置才不至于出现偏差。这些对采取坐标定位的触摸屏来说都不需要，再其次就是能检测手指的触摸动作并目判断手指位置。

Module 1756-PA75/B
The slots of the passive backplane consist of bus expansion slots. The bus expansion slot can select the extended ISA bus, PC bus and PCI-E bus according to the user’s actual application. PCIMG bus consists of multiple slots, and the number and location of expansion slots can be selected according to your needs. However, according to different PCIMG bus specification versions, various buses have requirements for combination and collocation. For example, PCIMG1.3 does not provide ISA bus support. This structure can reduce the mutual interference of logic signals on the board and reduce the impedance of the power supply. The bottom plate can be inserted into various board cards, including CPU card, display card, control card, I/0 card, etc.

From the technical principle point of view, the touch screen is a set of transparent coordinate positioning system, it is transparent, so it through material technology to solve the transparent problem, like digitizer, writing pad, elevator switch, they are not touch screen, secondly it is coordinates, fingers touch where is where, do not need two actions, unlike the mouse, is a set of relative positioning system, we can notice, Touch screen software does not need the cursor, but the cursor affects the user’s attention, because the cursor is used for the relative positioning of the device, the relative positioning of the device to move to a place to know where to go, which direction to go, every moment also need to keep giving the user feedback on the current position to avoid deviation. These are not necessary for the touch screen to take coordinate positioning, and then it can detect the touch action of the finger and determine the finger position.
