## Questions & Answers

**Q: What are the wiring connections to modulate the beam?  Thanks!**
A: There is a seperate 2 pin connection for the TTL circuit on the circuit board.

**Q: Do you have a diagram of the board? Was expecting this in the package. No paperword what so ever.**
A: The picture shows the old driver board. In fact, the driver board has been upgraded and the position of the interface has been adjusted. We have a new connection diagram of the driver board. (The pictures on the current product link cannot be modified)

**Q: Will this work in my 3018 Pro?**
A: THis does not have the power to burn or cut with any speed. Did you have a different use for it?

**Q: There are three 2 pin connectors on the circuit board. which connector modulates the beam? polarity?  please answer the question this time.**
A: The first is for power (red/black), the second is for modulation (shorted=off, or 0-off +5 =on) and the third is for wiring a safety on/off switch.
