在運(yùn)用戶外LED顯示屏?xí)r，經(jīng)常呈現(xiàn)無法加載的景象。大印象從下面的幾個方面來分析下LED顯示屏加載不上的因素。
In the use of outdoor LED display, often rendered unable to load the scene. Dayinxiang from the following aspects to analyze the factors under the loading on the LED display.
1、查看跳線帽是不是松動或掉落；假如跳線帽沒有松動景象，請保證跳線帽的方向準(zhǔn)確。
1, check the jumper cap is not loose or fall; if the jumper cap does not loose the scene, please ensure that the jumper cap accurate direction.

2、查看并承認(rèn)用于銜接操控器的串口線為直通線，而非穿插線。
2, to see and recognize the serial port for the convergence of the controller for the straight line, rather than interspersed lines.
3、查看并承認(rèn)該串口銜接線完好無缺而且兩頭沒有松動或掉落景象。
3, check and recognize the serial connection line and ends without loosing or falling flawless and perfect scene.
4、對照LED顯示屏操控軟件和自個選用的操控卡來挑選準(zhǔn)確的商品型號、準(zhǔn)確的傳輸方法、準(zhǔn)確的串標(biāo)語、準(zhǔn)確的串行傳輸速率并對照軟件內(nèi)供給的撥碼開關(guān)圖準(zhǔn)確地設(shè)置操
4, control LED display control software and the control card from choosing the right goods model and accurate transmission method, accurate on posters, accurate serial transmission rate and control software in the supply of the dial switch map accurately set.
控系統(tǒng)硬件上的位址位元及串行傳輸速率。
Address bits and serial transmission rates on the hardware of the control system.
5、保證操控系統(tǒng)硬件已準(zhǔn)確上電。
5, to ensure that the operating system hardware has been accurately power.
6、如經(jīng)過以上查看并校正后依然呈現(xiàn)加載不上，請用萬用表丈量一下，是不是所銜接的電腦或操控系統(tǒng)硬件的串口被損壞。以承認(rèn)是不是應(yīng)送還電腦廠家或?qū)⒉倏叵到y(tǒng)硬件送還檢查。
6, such as after the above view and correction is still not loaded, please use multimeter to measure, is not connected to the computer or control system hardware serial port is damaged. That is not to be returned to the manufacturer or computer will control the hardware check back.
總歸，LED顯示屏加載不正常的因素，有可能是商品本身的疑問，也有可能是你在運(yùn)用過程中操作不當(dāng)所形成的。只要認(rèn)真思考或?qū)枏S家，很簡單找到疑問的本源。
