LED显示屏——“诺瓦”系统调试方法
一、发送卡：
1、双击“”，打开诺瓦系统软件，点击“用户”，高级
用户登录，进入用户登录界面，输入正确的密码。
密码：“***”。
；
2、点击“显示屏配置”，选择正确的串口号，点击“下一步”，
进入“显示屏配置”界面如图：
备注：发送卡分辨率，显卡输出分辨率，显示器分辨率三者应
一致，如：1366*768。
3、当接收卡不是同一个程序版本时，LED显示屏可能会出现接
收卡所载的屏体颜色有色差。
这时我们可以通过更改程序版本以达到要求。
（1）、如1所示，打开软件，登录用户界面。
（2）、在登录界面空白处点击“左键”——>输入“******”密码，进入“程序加载”界面，如图：
在“程序路径”中选择适合自己LED显示屏的程序版本。
例如：
选择程序版本之后，点击“更改”。
二、千兆网卡；
对于一个只有几张接收卡的LED显示屏，客户要求不高的情况
也可以用千兆网卡。
千兆网卡的调试方法和发送卡的主要区别在于“程序加载”界面里的“程序路径”中的程序版本。
例如：发送卡：
D:\ProgramFiles(x86)\NovaStar\NovaLCT-Mars\Data\Data_Mars_3 .6.1.0\RVCard\MRV300_D
千兆网卡：
D:\ProgramFiles(x86)\NovaStar\NovaLCT-Mars\Data\Data_Mars_3 .6.1.0\SendCard\Tx600_
加载完成之后，点击“更改”——>“重新连接”。
![[诺瓦科技]解决LED显示屏常见的故障问题汇总](https://img.taocdn.com/s1/m/05a08a1483c4bb4cf7ecd133.png)
解决LED显示屏常见的故障问题，赶紧收藏吧！LED显示屏应用越来越广泛，我们在使用过程中或多或少会遇到一些显示屏故障问题。
当问题出现了，我们怎么才知道故障出在哪里?要怎么解决?小编将对这几个问题进行简单解析。
LED大屏幕属于电子产品，有时会出现各种故障，专业维护工程师根据经验，总结出LED显示屏的五大主要故障及解决方法。
第一、单元板出现整片屏幕不亮、暗亮的原因?1.目测电源连接线、单元板之间的26P排线及电源模组指示灯是否正常。
2.用万用表测量单元板有无正常电压，再测量电源模组电压输出是否正常，如否，则判断为电源模组坏。
3.测量电源模组电压低，调节微调(电源模组靠近指示灯处的微调)使电压达到标准。
第二、LED屏幕出现屏幕全黑的原因是什麽?在控制系统运用的过程中，我们偶尔也会遇到LED屏幕出现屏幕全黑的现象。
同样的一种现象可能是由各种不同的原因导致的，就连屏幕变黑的过程也会因不同操作或因不同环境而异。
比如它可能是一上电的瞬间就是黑的，也可能在载入过程中变黑，还可能是在发送完毕后变黑等等：1.请确保包括控制系统在内的所有硬体已全部正确上电。
(5V，勿接反、接错)2.检查并再三确认用于连接控制器的串口线是否有松动或脱落现象。
(如果在载入过程中变黑，很可能是因为该原因造成，即在通讯过程中由于通讯线松动而中断，故而屏幕变黑、千万不要以为屏幕体没有动，线就不可能松动，请动手检查一下，这对想要快速解决问题很重要。
)3.检查并确认连接LED屏幕及与主控制卡相连的HUB分配板的是否紧密连接、是否插反。
第三、载入不上或通讯不上的原因是什麽?通讯不上与载入不上的原因大致相同，可能是由于以下几种原因造成的，请根据所列各项与操作进行对照：1.确保控制系统硬体已正确上电。
(5V)2.检查并确认用于连接控制器的串口线为直通线，而非交叉线。
3.检查并确认该串口连接线完好无损并且两端没有松动或脱落现象。
4.对照LED屏幕控制软体和自己选用的控制卡来选择正确的产品型号、正确的传输方式、正确的串口号、正确的串列传输速率并对照软体内提供的拨码开关图正确地设置控制系统硬体上的位址位元及串列传输速率。
