3. Check and confirm that the serial port cable is intact and the two ends are not loose or fall off.
4. Select the correct product model, the correct transmission method, the correct serial port number, the correct baud rate, and control the LED display screen control software and the control card of your choice, and set the control correctly according to the dial switch diagram provided in the software. Address bits and baud rate on the system hardware.
5. Ensure that the control system hardware is properly powered up. (+5V)
6. If after the above check and correction still occurs, please use a multimeter to measure if the serial port of the connected computer or control system hardware is damaged. To confirm whether the computer manufacturer should be returned or return the control system hardware to the test.
In short, the reason why the LED display is not properly loaded may be due to the product itself, or it may be due to improper operation during use. It is easy to find the source of the problem as long as you think or ask the manufacturer seriously.
Carbon Steel Nut
Hexagon nuts (also known as finished hexagon nuts) are available in ASTM A563-A and are compatible with mild steel Bolts, such as ASTM A307, ASTM F1554 Grade 36, SAE Grade 2 and AASHTO M183. SAE Grade 5 and Grade 8 nuts are also available in finished style. Since hot-dip galvanizing usually increases the thickness of the threaded part of the fastener by 2.2 to 5 mils, the thread size of the galvanized hexagon nut is too large to compensate for the anti-corrosion coating on the bolt.
Chinese hex nut manufacturer Hongchuang Hardware provides hex nuts of various materials, such as carbon steel, stainless steel, alloy steel, titanium, etc.
