4.4.3 Serial RS232 Interface
The 9-pin serial interface RS232 is used for the communication between the laser and the Raycus
software. It can be used to communicate with the Raycus software or the software of the Raycus software
which integrates the communication protocol of Raycus. The definition is as follows.
Pin No.
4.4.4 Analog Interface XP4
The analog interface, an 8-core Harting interface, is used to control the output power of the laser by
analog in AD mode, and can also monitor the output light and power feedback signals of the laser. The
interface definition is shown in Table 9 below.
