The MICRO DNC is used to send and receive CNC program files between
a CNC control and a USB memory stick. The MICRO DNC connects to the CNC
control via RS232 port. It can also ‘drip feed’ the CNC control - providing that the CNC
control is capable of receiving and executing a G code program via its RS232 port. .
