MICRO DNC 3A (called DNC 3A) is a device used to transmit or receive G-code programs with CNC machines - that is the basic function of the DNC 3A device. DNC 3A is designed to optimize and simplify program transmission to CNC machines (compact, does not take up working space, very high stability, good anti-interference), replacing computers or some other devices. Complex old equipment to transmit G-code program to cnc machine. You can transfer programs from the DNC 3A's memory (4GB memory) or transfer programs from a USB stick (up to 64GB memory). can transfer the program into the CNC machine memory, or drip large programs to the CNC machine through the CNC machine's DNC function. You can receive data from the CNC machine to the DNC 2C device (program storage, tool offset parameters, CNC machine parameters...) DNC 3A can connect to a computer via wireless LAN (wifi network). There will be software installed on the computer From the software on your computer, you can copy the program from your computer to DNC 3A or vice versa from DNC 3A to your computer. notification can be sent to the machine operator (notification on the DNC 3A screen). Execute the program transmission command for DNC 3A from the software on the computer, you can monitor the status of the DNC 3A device (transmitting or stopping, displaying % of the program being transmitted...) ATTENTION. Computers and DNC 3A connected to the same WIFI network can connect to each other. If connecting to different wifi networks, it will not work The device shell is made from high quality plastic, on the back there are super strong magnets that can be used to attach the DNC device anywhere on the CNC machine body. DNC 3A device has two USB ports (you can only use 1 USB port at a time) The device has 1 RS232 port to connect to CNC machines There is 1 power port to supply 12V DC power from outside Baud rate from 1200-115200 data bits (7-8) stop bits (1-2) parity setting - (even-odd-none) There is an automatic transmission mode when the program ends (used for processing parts with many repetitions). ?auto resend? Package includes DNC 3A, 2 meter long RS232 DP9-DP25 cable, 12V AC-DC power adapter Customer service throughout the process of customer use.
