All users of Heidenhein controllers can use a software (TNC Remo NT) from Heidenhain to transfer programs directly from their machine to/ from a PC without leaving the machine. This program can be downloaded from the Heidenhain website.
They can also install a Serial Device Server (approx. USD 120 from Moxa or Sena) to connect their control via network to a PC. This way they will not be limited by the distance limitation of the RS-232 cabling system (and interference problems). This serial device server is connected on one side to your serial output of the control and on the other side to your internal network. The software for the serial device server is then installed on your PC where the serial device server is then seen as an additional COM Port on the PC. Program files can be stored on this PC which will act as a server.
