2. Direct numerical control - Wikipedia

   en.wikipedia.org/wiki/Direct_numerical_control

   Direct numerical control (DNC), also known as distributed numerical control (also DNC), is a common manufacturing term for networking CNC machine tools.On some CNC machine controllers, the available memory is too small to contain the machining program (for example machining complex surfaces), so in this case the program is stored in a separate computer and sent directly to the machine, one ...

3. RS-232 - Wikipedia

   en.wikipedia.org/wiki/RS-232

   In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data. It formally defines signals connecting between a DTE ( data terminal equipment ) such as a computer terminal or PC , and a DCE ( data circuit-terminating equipment or data communication ...

4. List of EIA standards - Wikipedia

   en.wikipedia.org/wiki/List_of_EIA_standards

   RS-232 (or EIA-232) electrical characteristics, single-ended voltage digital interface circuit (serial data communications) RS-259, 75Ω RF high power RF connectors, (EIA RF Connectors) EIA-274 is the most common NC code format. In the machine tool industry it also known as G-code. In the PCB industry Standard Gerber, now revoked, was based on it.

5. FANUC - Wikipedia

   Today, FA products continue to be used to create automated systems in over 100 countries around the world. It is common for the FA group to deliver controls and servomotors to machine tool builders who integrate them into a conventional CNC machine. A significant proportion of the world's CNC machines are powered by FANUC controls.

6. USB communications device class - Wikipedia

   en.wikipedia.org/wiki/USB_communications_device...

   This class can be used for industrial equipment such as CNC machinery to allow upgrading from older RS-232 serial controllers and robotics, since they can keep software compatibility. The device attaches to an RS-232 communications line and the operating system on the USB side makes the USB device appear as a traditional RS-232 port.

7. Serial port - Wikipedia

   en.wikipedia.org/wiki/Serial_port

   The only connector specified in the original RS-232 standard was the 25-pin D-subminiature, however, many other connectors have been used to save money or save on physical space, among other reasons. In particular, since many devices do not use all of the 20 signals that are defined by the standard, connectors with fewer pins are often used.

8. Highway Addressable Remote Transducer Protocol - Wikipedia

   But it is often converted to RS485 or RS232. According to Emerson, [2] due to the huge installation base of 4–20 mA systems throughout the world, the HART Protocol is one of the most popular industrial protocols today. HART protocol has made a good transition protocol for users who wished to use the legacy 4–20 mA signals, but wanted to ...
