Today, Shanghai Yajin has given some instructions on how to connect the computer to the electronic truck scale. I hope to help you in the process of installing the truck scale.
First, the required equipment is: data cable, computer, weighbridge software, list printing paper, dot matrix printer.
1. First, there must be an electronic truck scale meter connected to the computer COM port data line, you can use the double core wire 0.4-0.5 flat, if you use the network cable or power cord instead of soldering to the corresponding pin angle to achieve data connection and intercommunication , easy to break, and not resistant to interference.
2. Different series of electronic truck scale instruments have different welding wiring methods.
3. The connector usually needs a 9-pin female connector to connect to the computer. Because the computer is a 9-pin male, the other end must be a 9-pin female. The instrument must be based on the actual situation. It is useful for 25-pin, 9-pin male, 9-pin female, 15-pin male, etc. The 9-pin female (connected to the computer) generally uses 2 feet, 3 feet, and 5 feet. It needs to be soldered according to the instructions in the factory manual to the 9-pin, 3-pin, and 5-pin of our computer. Yes, generally 2 feet is connected to the computer interface RXD, 3 feet is connected to the instrument to connect the electronic platform computer interface TXD, generally 5 feet is the ground GND.
4. We can weld these three wires accordingly.
