4.4.3 Serial RS232 Interface
The 9-pin serial interface RS232 is used for the communication between the laser and the upper
computer. It can be used to communicate with the PC software of Raycus or the software of the upper
computer which integrates the communication protocol of Raycus. The definition is as follows.
Table 8 RS232 serial interface definition
RXD, serial receiving pin of laser
TXD, serial transmitting pin of laser
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.
Table 9 XP4 analog interface definition
0V~10 V analog signal, laser power control signal in AD mode ,
0V~10 V corresponding to 0%~100% output power
Power amplifier voltage output.
0 V: 0% laser power output;
8 V: 100% laser power output.
Reference ground for power amplifier voltage
High back-amplification voltage (reserve, no use)
Reference ground for high backup voltage (reserve, no use)
