Serial Port (X31)
The RS-232-C/V.24 serial port is located on the rear panel. The
following devices can be connected to this port:
 Printer with serial data interface
 Personal computer with serial data interface
A printer, or computer may be connected to the serial port. Part
programs, and configuration files may be sent to a printer, or
computer. Remote commands, remote key codes, part programs, and
configuration files may be received from a computer.
For operations that support data transfer, an IMPORT/EXPORT soft
key will be available.
 The BAUD field can be set to 300, 600, 1 200, 2 400, 9 600, 19 200,
38 400, 57 600, or 115 200 by using the LOWER, and HIGHER soft
keys.
 The parity can be set to NONE, EVEN, or ODD using the soft keys
provided.
 Data Bits in the FORMAT field can be set to 7, or 8 using the soft
keys provided.
 The STOP BITS field can be set to 1, or 2 using soft keys.

LINE FEED field can be set to YES if the external device needs a line
feed to follow a carriage return.
 Output tail is the number of carriage returns that will be sent at the
end of the measured value output transmission. The output tail is
initially 0, and can be set to a positive integer value (0 - 9) by using
the numeric hard keys.
The screen shown here are the default settings.
The serial port settings will be retained on a power cycle. There is no
parameter to enable, or disable the serial port. Data will only be sent
to the serial port if the external device is ready. Refer to Data Interface
section for cable connection, and pin assignments.
To export data to a serial port printer, press the IMPORT/EXPORT soft
key. The data is exported in an ASCII text format which can be printed
directly.
To export, or import data between the ND 780, and a personal
computer, the PC must use terminal communications software such
as TNCremo. TNCremo is available for free at:
http://filebase.heidenhain.de/doku/english/serv_0.htm. Contact the
nearest Heidenhain distributor for further details. This software
processes the data being sent, or received over the serial cable link.
All data transferred between ND 780, and the PC is in ASCII text
format.
Data is transferred in the following sequence: Start bit,
Seven data bits, Parity bit (even parity), Two stop bits. This
is the default setting.
