The data interface on your ND display unit enables you to use a printer,
a PC or the HEIDENHAIN FE 401 floppy disk unit for transferring
measured values or programs.
The interface is permanently set to the following data format:
1 start bit
7 data bits
Even parity bit
2 stop bits
The baud rate is set with parameter P50. See “Program Output over
RS-232-C/V.24 Interface” for instructions on how to start output to a
printer, a PC or the FE 401.
For connection to peripheral devices you can use either full wiring
(figure at upper right) or simplified wiring (below right).
