Digital Dream CNC DDUM4 V1.0 4 Axis Mach3 USB Card 4 Axis USB Controller Board for Win7/8/XP

DDUMV1.0X is a CNC systerm based on mach3. You do not need to add other hardware, and you can complete the signal conversion from the G-code to the movement of the stepper motor drive control. This card is compatible with most stepper drives and servo drives. And it is perfect weapon to replace mach3 parallel interface board.
Functions and define of each module: A. USB PORT, thIS INTERFACE IS connected to the computer through a USB line. You can use the software mach3 to control this board, nnote that you should use a USB2.O cable with shielding and ferrite core and cable length should be not more than 2 meters. B)5V General input port, IN1-12,The interface uses opto-isolated, using common positive input, COM is used as the common port.
C)High 8 general IO out interface, have a current drive capability within 10MA.
D)5V General Input poprt IN13-IN26, it`s a 2.54mm double pin port.
E)The Yellow input terminals is power input within 15-36VDC.
F)2 ralay output, relay R1 and R2 are set as O17 and O18 in mach3, each relay`s 3 teminal are CLOSE/COM/OPEN from up to down.
G)Spindle PWM speed port, the interface requires a reference voltage,eg. 10V, the port is set as 10PIN 0-10V out, GND from up to bottm.
H)High 8 General IO out interface, have a current capabitity within 10MA.br>Requirements of computer:
