c) Pin 17 receives external 5V DC voltage to provide power supply for inside isolate chip
of DB25, thus the input and output signals are valid.
d) Pin 18 is the start signal of the MO. Pin19 is the input for the optical output signal. The
electrical level for both Pin18 and Pin19 are 5V. Before turning on Pin 19, MO signal
must be switched ON, in other word, the signal of Pin 18 must be ahead of Pin 19 at
least 5 ms, and otherwise the laser machine may be damaged.
e) Pin 20 provides control of the frequency. The frequency range should be 1kHz~2000
kHz, depends on the varying power levels of different laser machines.
ATTENTION: The frequency signal must be ahead of the EM signal at least 5 ms,
otherwise the laser machine may be damaged.

1) Marking machine sends the command to the laser machine by the Pin2 on the
DB25 port, meanwhile sends the clock signal to the Pin3. The comment is the
binary form, and delivers the most significant bit as the priority.
2) The order structure from marking machine to the laser machine is:
0xA5+instruction code.
3) 0xA5（A5h）is the comment byte to active the laser pulse duration control port.
0xA5 and the following data will be directly sent as the serial input form to the
Pin2 on the DB25 port.
4) The input data length is 4 bytes: the first byte of instruction code should be 0x01
（01h）,the second byte and the third byte are the value of the binary coding of
laser duration (for example: 200 is the decimal number of 0x00C8, represents the
setting pulse duration is 200ns).
5) Pin22 is the Enable signal. The Enable should achieve high state at least 10us
before Pin2 and Pin3 changing. The Enable should achieve low state at least 10us
after Pin2 and Pin3 changing. Figure 14 shows the adjustment process of laser
duration control.
6) Pin19 should decrease to low state before adjusting laser pulse duration.
7) Optional pulse width :10\20\30\60\100\200\250\350ns.

For example, if using Beijing JCZ Technology Co. marking card to adjust laser pulse
duration, the setting processes are described as follows:
a) Make sure the power supply, DB25 cable, control card and computer are correctly
connected, and then turn on the 24V power supply.
b) Open Ezcad2.7.6 (or other versions), then click ‘F3’, the configuration parameter
should show up, select ‘Fiber’ in the category of the ‘Laser Control’ panel, follow that
select ‘IPG_YLPM’, and then close this window.
c) Pulse duration can be modified by the ‘Duration’ on the right side of the window. If the
setting duration is smaller than the limiting minimum value, the duration of output laser
will be 2ns (minimum). If the setting duration is larger than the limiting maximum
value, the duration of output laser will be continuous work (maximum). If the setting
duration within the range, the duration of output laser will tend to the smaller side.

4. Operation Regulations
4.1. Pre-inspection
a) Make sure the device appearance is in good condition and the output fiber is neither
excessively bended nor broken.
b) Make sure signal line of laser and marking system are properly connected.
4.2. Operation procedures
a) Starting procedures
Please make sure the control system is on before you turn on the fiber laser. Only after
at least 1 minute since the power turned on, the subsequent operations can be proceeded.
b) Frequency set introductions
The frequency setting range is from 1 kHz to 2000 kHz(The actual frequency range of
each pulse width is showed in the Table 3).
c) Laser marking checking
For the device initial testing, first turn the power down to zero without turning on the
marking system after the device is successfully started. Then draw a quadrate, marking
continuously while slowly increasing the power from 1% to 100% at the same time.
Meanwhile, use a ceramic material to observe the laser and the laser should become
stronger, otherwise shut down the device and check.
If operating normally, the marking system can be used in common order afterwards.
4.3. Cautions
a) Marking frequency must be in the range of 1 kHz to 2000 kHz(The actual frequency
range of each pulse width is showed in the Table 3).
b) It should not modify the frequency while marking.
c) Stop marking first before shutting down the device, then turn the power down to zero
and cut the power off.
