1. Full support for MACH3 and other computer software that supports parallel port control.
2. Separate USB power supply and peripheral power supply to ensure computer security.
3. External wide voltage input, 12-24V, and anti-reverse connection function.
4. All input signals are isolated by optical fiber, which can be connected to emergency stop, tool setting, limit, etc. to ensure computer safety.
5. One relay output port can control the spindle switch. The output is P17.
6.A 0-10V analog voltage output isolated by optocouplers can control inverters with corresponding analog interfaces. Spindle speed. The output is P1.
7. Open all 17 ports, can be connected to the driver with optocoupler, can control 5-axis stepper motor.
8. P1 is used as PWM output, which can control the spindle governor with optocoupler input.
9. It can be connected to the driver of common cathode or common anode and input level is 5V.
10. Print all port names at a glance.
