Most older CNC machines have very small memory, which often makes the program loading into memory to use several small programs or have the ability to drip the program's ""DNC function. Transmission of the program to the CNC machine takes place through the RS232 port on the CNC machine The traditional DNC solution uses a computer with specialized DNC software installed (such as CimcoEdit, DosteskDNC, ProDNC...) to transmit the machining program to the CNC machine. This solution has some disadvantages as follows: - Placing a computer set near the CNC machine occupies the workshop area. Power cord and rs232 cable will be very problematic for the CNC machine workplace - Computer manipulation takes a long time and many steps (computer startup, software startup, installation, selection...). - Computers sometimes do not work properly or are attacked by viruses, causing work interruptions, reducing productivity. With the above disadvantages of the traditional solution, we have designed to integrate the most needed functions with the goal of a compact product and optimized operation, in order to improve productivity and economy in the future. In the process of using CNC machines, the DNCdevice product was born - The transmission program for CNC machines. With DNCdevice, the programmer after creating the G code on the computer will copy the file to the USB, then bring the USB pin to the DNCdevice in the CNC machine area. or you can copy the program from your computer to your DNC device remotely via wifi or wired LAN "RJ45 PORT" (with some products with wifi connection function) MICRO DNC 3A is equipment used to replace old computer transfer data. When using your computer to transfer data to the CNC machine, it will have some disadvantages: the connection will not be stable, it will waste the surface. So the MICRO DNC 3A device enhanced these benefits to make data transfer easier, faster, and more convenient. MICRO DNC 3A can connect to a computer via wireless LAN (Wifi) to control transmission, copy program between DNC DEVICE and computer MICRO DNC 3A has 4GB of internal memory, has 2 USB 2.0 ports for reading programs in the USB stick transfer the program to the memory of the CNC machine transmit DNC drip program (works in TAPE mode) receive program or PC / PARAMETER from CNC machine Pack includes 1 DNC 3A, 1 12VDC ADAPTER, 1 RS232 DP9 (Female)-DP25 (Male) cable We have a long term customer support regime, throughout the operation of the device. and can help you configure your device to work on CNC machines
