The two main parts of computer laser engravers:

The upper computer—includes PC and other relative accessories such as scanner and printer

The PLC---computerlaser engraver and relative parts

The upper computer—PLC are connected to be an integrated system by RS-232 serial communication cables. The characters and graphics generated in the computer will be sent to engravers through serial port and the laser group will work under the control of the microcomputer on the engraver. Thus the serial port cable is the bridge to connect and communicate the two parts. The data in the computer can be sent to the engraver successfully on the condition that the cable is working well.
