First, LED advertising screen how to set parameters
Although the range of LED display is more and more advertising, most people still don't know much about the basic settings of the led display. How to set the parameters of the led display is the first thing to do.
Single and double color strip screen, this setting is relatively simple, it is often said that the control parameter setting, the user can change it freely, all kinds of controllers are similar, but some invisible parameters some software must be shortcut keys to call out, or need engineering password, treat these Must have certain professional knowledge.
In short, different control card settings are not the same, you can go to the website to download the control card manual, or after the sale.
Second, how to set the outdoor led display parameters
A light bulb is a point. Then you look at what your cell board looks like. How much is much longer and then you can use basic mathematical calculations. The indoor is generally 64*32, and the outdoor is generally 32*16.
Third, the main functional requirements analysis and model construction of led display
Due to different manufacturers, the number of parameter items of the LED display screen is also different, but basically there are more than twenty items in each display screen. After analysis and classification, it can be divided into core parameters, basic parameters and auxiliary parameters. .
(1) Core parameters
The core parameter is a parameter required for the led display. If the setting is not correct, the light is not displayed, and the display is burned. The core parameters include cascading direction, OE polarity, data polarity, led display type, color, scanning mode, walking order and line order.
(2) Basic parameters
The basic parameters are the basic parameters of the led display. If the settings are not correct, they cannot communicate, display or display abnormally. Basic parameters include display width, display height, control card address, baud rate, IP address, port number, MAC address, subnet mask, gateway, LED display refresh rate, shift clock frequency, and line blanking time A total of 12 items.
(2) Auxiliary parameters
Auxiliary parameters are parameters set for better display and control, including control card name, communication display mark, brightness, and switch screen time.
