Safety Instructions
Please read this section carefully before installing and using the
DLC2-PCIE control card. If you have any questions about this
document, please contact BJJCZ.
1. Safe operation steps
● Please observe all safety instructions for lasers (including but
not limited to descriptions and lasers, galvanometers and related
sections in this document)
● Turn on the laser power at any time after turning on the computer
power and galvanometer power. Otherwise, it may cause damage due to
an uncontrollable laser beam.
We recommend that you use a shutter to avoid damage from
uncontrolled lasers.
2. The security part of the customer's responsibility
● DLC2-PCIE is designed to control a laser scanning system.
Therefore, all safety instructions for the laser system should be
understood and implemented by the customer. The customer must
strictly comply with the relevant safety instructions and be solely
responsible for the safety of the laser system used.
● Security rules may vary from country to country. It is the
customer's responsibility to comply with all local regulations.
● Please check carefully before running the software. A software
error may cause the system to stop responding. In this case, the
galvanometer and laser are uncontrollable.
● Please avoid damage to the board caused by moisture, dust,
corrosives and foreign objects
● When storing and using the board, please avoid electromagnetic
field and static electricity damage. They can damage the
electronics on the board. Use an ESD bag to store the card; wear a
well-grounded ESD-preventive glove contact card.
● Please ensure that the board is stored in the environment of
-20°C to +60°C. The permissible operating ambient temperature is
25°C±10°C.
1. Overview
The DLC2-PCIE dedicated marking control card is a 2D/3D control
card specially developed for fiber lasers. It is connected to the
computer motherboard by PCIE interface.
1.1 How to identify the DLC2-PCIE control card
J16: galvanometer signal, DB15
J7: Laser control interface, DB25
J17: IO/Mark on the fly Universal IO port and flight marking
The front of the board is printed with the words "DLC2-PCIE_V2"
1.2 Main features
● Output FIBER laser control signal with DB25 socket
● The galvanometer control signal is a digital signal, which can be
directly connected to the internationally accepted digital
galvanometer.
