PS 2: If the voltage or current states of the laser are abnormal, the alarm might present
“
POWER ERR
”
due to using different marking card (for example: Beijing JCZ Technology Co.
marking card,).
PS 3: If the laser output system is abnormal, the alarm might present
“
SYSTEM ERR
”
due
to using different marking card (for example: Beijing JCZ Technology Co. marking card,).
7) Introduction of laser pulse duration control.
PIN2, 3, and 22 on DB25 port not only used for the foundation control of the laser machine, but
also achieves the pulse duration control as the extender.
Table 6 Laser duration control signal.
PIN Name Description
2 Serial input
The setting of the data bits synchronize with rising edge of the
serial clock.
3 Serial clock Serial clock , frequency range: 10kHz
～
1MHz.
22 Pulse duration control Enable
High
：
Enable
，
PIN2 and PIN3 control the pulse duration;
Low or disconnected
：
Disable
The principle of the laser duration control is described as follows:
a) Marking machine send the command to the laser machine by the PIN2 on the DB25
port, meanwhile send the clock signal to the PIN3. The comment is the binary form, and
delivers the most significant bit as the priority.
b) The order structure from marking machine to the laser machine is:
0xA5+instruction code.
c) 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.
d) 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).
e) 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 7 shows the adjustment process of laser duration control.
f) PIN19 should decrease to low state before adjusting laser pulse duration.
