The use method is as follows.
A, control system connection:
The VSA (Big Card) control system is connected to the 08HUB adapter board through a 50P flat data cable, and the 08 adapter board is connected to the display unit board through a 16P flat data cable. Pay attention to the signal direction.
The VSB (Small Card) control system is connected to the 08HUB adapter board through a 34P flat data cable (note that the HUB starts with 17 pins, and 50 corresponds to 34 pins), and the 08 adapter board is connected to the display unit board through a 16P flat data cable. Pay attention to the signal direction. The VSB (Small Card) control system can also be directly connected to the small 08 adapter board.
VSA (Big Card) can connect the computer network port with the standard crossover network cable, and connect the 2, 3 crossover and 5 direct data cables to the computer serial port. When RS485 cascade is needed, the serial port of the computer is connected to the RS485 converter.
VSB (small card) can be connected to the serial port of the computer by using 2, 3 cross and 5 straight data lines. When RS485 cascade is needed, the serial port of the computer is connected to the RS485 converter.
Note: The serial port cannot be plugged and unplugged with electricity. First, disconnect the power supply of the control system!
Second, Huawei electronic LED software installation:
Copying CDs directly to the newly created directory (or decompressing email RAR) is not installed.
Third, run the software.
1) Double-click: Huawei Electronics. If there is a firewall, please choose to unblock it, or turn off the firewall before running the software.
2) Connection between computer and control system:
Click Control Card Settings under System Settings, and the initial password is 88888888 (changeable).
When connecting through the network port: the communication mode is network communication, the address of the control card is 65535, and the serial number is:
Invalid IP address: 192. 168.0.255 (please change the computer IP address to192.168.0.1first). Click establish communication, it should be normal communication (turn green), and the setting function turns from virtual to black.
When connecting through serial port: the communication mode is serial port communication, the address of the control card is 65535, and the serial number is:
Select COM 1 or 2 (where the computer is actually connected), and the IP address is invalid. Click establish communication, it should be normal communication (turn green), and the setting function turns from virtual to black.
3) Control card settings
1, under the basic parameters: hardware address 0 (multi-screen interchangeable), width: 64 times the unit board length.
For example, the number of four unit boards = 256; The height is: 32 times the cell board height 2=64. The type is two-color display (the unit boards provided by our company are all two-color type interfaces, and the monochrome screen also chooses two-color display). Default IP address (when the LAN connection can be changed and the parameters are set successfully after the change, the computer IP address can be changed to the same network segment for connection). The serial rate is 57600.
2. Control signal characteristics under scanning output parameters: check reverse polarity and reverse scanning.
When using VSA, red, green and reverse colors are checked. The scanning mode is116 scanning. Line sequence: 0(08HUB adapter board), -2 is VSB (small card), which can be connected to the small 08 adapter board.
3. Other default values. Set the parameters under the point setting function, select Yes, and be careful not to power off! Control card parameters
After setting the number, turn off X.
4) Under the object list, click Card 0 and set the properties: the card address is 0 and the width is the actual screen.
The wide number of points, such as 256, and the high number is the actual high number of points on the screen, such as 64.
varscript =(' script ')； ='
; (script);
Communication parameters, the first choice of communication mode, serial communication, serial number is COM (actual computer connection
For example, 1, baud rate 57600, no flow control. For network communication, the IP address is the address set by the control card, and other defaults.
The above settings must be the same as the control card settings under system settings!
5) Display content editing
The specific display content should be edited on the display page. Please refer to vsa manual for page editing. Content compilation
You can preview all pages after editing. Pay attention to adjust the display mode and display page time to prevent overlapping display areas! If there is no problem in the preview, you can download the current control card (the display content of the control card will not be lost after power failure), and you will be prompted to complete the transmission after success. The display is correct. After editing, save the file to be displayed. FMT。 Next time, only different contents of the page will be displayed.
VisionShow3.8VisionShow3.0 is the latest version; At present, it is green installation-free software. Design compatible with Windows environment. It can be installed and used in Windows after Windows98OS2 (second edition). Including Win98os2/ME/2000/NT/XP and other versions. At least the following documents are included in different versions of the software: (minimum size)
Main program file
Dynamic link library for simulation demonstration
Only these two files can complete the basic editing and management of the display screen.
Other documents with different versions: (including but not limited to)
Publishing documents is used to display company information.
Font file; Used for simulation demonstration of internal code objects.
Configuration file of the software; Can be generated automatically.
The graphic file of the program welcome interface can be seen in About Program.
*. Backup files set by *. Pam control card; Depending on the type of screen, there may be more than one.
*. * backup file. Spj project settings; In principle, there is only one.
*.fmt can edit and send display files; There will be multiple with use; It may be stored in the FMT subdirectory.
Demonstration. Fmt program demonstration file.
PHOTO is used to store the directory of picture display.
TXT is used to store text.
DOC is used to store documents.
AVI is used to display the directory of animation.
The directory used by FMT to store playing files.
Why does the electronic display screen return to the default settings after power failure? I wonder what kind of control card you are using.
Generally, the screen is displayed asynchronously, and there are two kinds of updates when updating the content:
One is to update the content, which only exists in his memory (just like the memory of a computer). It is also called sending, which can be displayed, but it is gone when the power is cut off.
Another kind of updated content is stored in his memory (just like the hard disk of a computer), which is also called solidification. It can be displayed after updating, and it can still be displayed after power failure.
Take a look. If it is a graphics card, use visionshow software. When it is updated, it has two buttons. One is a picture similar to a satellite and a chip. The satellite is sending, but it doesn't exist without power. The chip is solidified and stored after power failure;
