85cm,110cm,130cm cross setting: cross resolution choose 64x64dot, baudrate: 9600

 Set cross open and close time

Set cross brightness 4 levels

Other reasons can not get connection:

1-Distance too far (>100meters) between the Led cross and the computer

2-Too many walls or houses obstacles

Why Knowing The LED Density Is Important When Purchasing LED Signs

Why Knowing The LED Density Is Important When Purchasing LED Signs?

Reason #1

LEDs have a unique degredation pattern. They lose approximately 20% of their brightness in the first 2,000 hours of use. After that the loss of brightness slows down to the point where they will last for approximately 100,000 hours total. This is true for all LEDs, there is no way around it, so don’t be fooled by talk of ‘special’ LEDs.

That means that Outdoor LED Signs which are rated at 5,000 NITs  will drop to approximately 4,000 NITs in the first 3 months.

For those of you who do not know,  a NIT is a  measurement of brightness, in North America the sun average sunlight is rated at approximately 5,000 NITs.  So, an LED sign must be at least that bright to compete with direct sunlight. For the sake of comparison, a computer monitor will range from 250-500 NITs which is why it is hard to see your laptop screen outside during the day.

The more LEDs there are in each pixel, the higher the LED Density is, the brighter the sign will be.

It is better to have an LED Sign with a high LED Density. This will help to maintain the brightness level of your sign.

Reason #2

One way companies who use lower LED Densities compensate for this lower brightness is to ‘overpower’ the LEDs. This means they put more electricity into each LED to make it brighter. This increases the degredation rate of the LEDs shortening their lifespan.

If an LED Sign has more LEDs in each pixel there will be no need to overpower the LEDs which will not only reduce the amount of electricity your sign uses but will help to preserve your LEDs and their brightness.

Conclusions

When you are shopping around to find LED Signs to invest in, make sure you select one with a high LED Density.  Also, make sure the sign you are looking to investing in is rated at 5,000+ NITs. This will help to protect your investment and insure you get the maximum benefit possible for the entire life of your LED Signs.
