(1) First of all, connect the weighing instrument and the computer, which can be welded to the corresponding pin angles with network cables or power cables to realize data interconnection. (The connection gauge is 15 pin welding line to the two corners of pin 7 and pin 8, and the corresponding connection computer is 9 pin welding to the two corners of pin 2 and pin 5. )

(2) After connecting the cable, connect the pressure gauge with the 15 pin, and insert the parallel port into the 15 pin slot behind the pressure gauge.

(3) The other end of the cable is connected to the computer, and the 9-hole plug is inserted into the COM 1 port behind the computer.

Of course, the wiring of different instrument models is slightly different. Common connection methods are listed below:
