Chapter 5 Operation Guide ◎ Laser GND (DB-25 pin 10-15,24) and laser 24VDC return (BLUE CABLE) are connected inside the laser module. No connections are allowed between these terminals outside of the laser module. ◎ Inside the module the common ground is connected to the laser housing via 470 Ohm resistor and parallel 47nF capacitor. - Page 23 Chapter 5 Operation Guide Latch(Latches power setting into the laser by the rising edge) 14,15 Ground 24，25 Floating 11，12，16，21 Laser alarms (see alarm codes in the table below). +5±0.25VDC power supply input for pin 16，21 Laser alarms status (see alarm codes in the table below).

- Page 24 Chapter 5 Operation Guide 2.Digital Control Interface (DB-25) Function Description （1）The laser is controlled via signals applied to the DB-25 connector. Please refer to the connector interface description table above for 5.2.1 pin designation and operating levels. （2） Pins 1 to 8 are the 8 bit bus for the output power setting. Pin 1 is the least significant bit and pin 8 is the most significant bit.
- Page 25 9. Data on the pins 1-8 should be stable for 1us before and 1us after the rising edge on pin 9. Stability of the data on the Pin 1-9 out of the above mentioned time frames is not required. Maxphotonics recommends supplying single positive pulse with duration longer than 2us to latch the data into the laser.
- Page 26 Chapter 5 Operation Guide （5）Pin 18 is the Emission Enable (EE) signal. The Emission Enable input should be switched ON at least 5ms earlier than the Emission signal is switched ON. After switching ON Emission Enable input, the laser starts to consume more electrical power and emits residual optical power to the output even when EM pin 19 is LOW (Emission).
- Page 27 Chapter 5 Operation Guide rising edge on the pin19. If the HIGH level was applied to the pin 19 before supplying voltage to the PCB, the laser does not recognize that as the Emission switching ON signal. The pin 19 should be dropped and set to HIGH level again.

Chapter 5 Operation Guide （9）Pin 23 is the “Emergency stop” input. It should be set to HIGH for normal operation. In case of dropping this pin to LOW state (even for a short period) the laser automatically switches OFF (similar state when both EE and EM are OFF) independently of other control signals. - Page 29 Chapter 5 Operation Guide （7）Switch the EE ON applying HIGH to the pin 18. （8）Wait 5ms. （9）Laser can be fast modulated via Pin 19 and the laser state of ON or OFF can be set with a HIGH or LOW input signal respectively. Switching ON/OFF of the laser has a finite rise/fall time (refer to the specification for the particular model).
- Page 30 Chapter 5 Operation Guide operate at the minimum specified PRR. （3）The power setting can be changed during the laser operation by applying updated values to pin 1-8 and latching them into the laser via pin 9. The laser will respond to the changes on the subsequent specified rise time.

Page 34: Chapter 6 Common Fault Treatment
Chapter 6 Common Fault Treatment 1-Laser Emission Failure （1）Make sure the connection of power supply is correct.(+24VDC and GND connect correctly? Earth the ground wire?) （2）Make sure the E-STOP switching is released, Emergency Stop Input is high when the laser is in normal operation. （3）Make sure the power supply is in normal condition, and check its output without and with load( connected with the laser). - Page 35 Chapter 6 Common Fault Treatment （3）Inspect whether other optical lens are clean, such as red light combiner, galvanometer, field lens. （4）Inspect whether optical output is covered or not and make sure the isolator output terminal and galvanometer are at grade when installing. （5）Power loss out of laser operation lasting 20,000 hours is normal phenomenon.
