1. Products brief introduction
USBCNCV4.0 is a high performance motion controller which based on PC software USBCNC control, the system can complete the conversion from G code to connect stepper motor’s driver motion control signal without requiring any additional hardware and software. This control card is compatible with most stepper driver and servo driver, it is a perfect controller that instead of parallel Mach3 interface board.

2. Computer system requirement
Minimum configuration:
1) CPU:1GHz
2) Memory: 512MB
3) 500MB free disk space
4) DIRECTX9 graphics device with WDDM 1.0 or higher driver
5) USB 2.0 interface
6) Net FRAMEWORK 3.5SP1
7)Win XP, not Win7

The recommended configuration:
1) CPU:2GHz dikaryon
2) Memory: 2GB;
3) 1G free disk space
4) DIRECTX9 graphics device with WDDM 1.0 or higher driver
5) USB 2.0 interface
6) Net FRAMEWORK 3.5SP1

3.Production appearance and size
1. After the revision,V4 version using the red PCB board, PCB size is 135.3*82.5mm.;
2. The front of the narrow edge placed with USB communication interface and DB9 hand control interface for the convenience of customers drawn from the case panel directly;
3. The back-end of narrow edge is power input and output interface and 3 relay output interface; relay is strong interference source, relay away from the design of main control chip, it is conducive to the stability of the board;
4. One of the two wide sides is stepper motor and principal axiscontrol signal output;
5. The another side of two wide sides is the emergency stop, manual speed input, limiting input interface; one side for the input, another side output connection mode is simple and convenient;
6. 5V and 12V power module compact independence, security, stability;
7. External ensure the stability of the system work effectively with crystal active and main control chip shield;
8. The software is USBCNC,not mach3,pls note!

4.Detailed functional introduction
A. Card input voltage: 15~36V;
B. Limit port working voltage: 12V;
C. Stepper motor control signal output voltage: 5V;
D. External power supply voltage: 12V;
Note: marked 15~36VDC is input interface, marked 12V is output interface, can not wiring wrong.
