9 Data interface
The HEIDENHAIN contouring controls TNC 407 and TNC 415 have two data interfaces:
one RS-232-C/V.24 data interface and
one RS-422/V.11 data interface.
Both interfaces may be utilised. The operator decides which of the two interfaces he wishes to use.
See also chapter "Data interface".
9.1 RS-232-C/V.24 data interface
HEIDENHAIN guarantees that, if properly connected, the serial data interface RS-232-C/V.24 will
transmit data correctly up to a distance of 20 m between the logic unit and the peripheral unit.
The connection to the peripheral unit is made via a cable adapter which is attached to either the
operating console or the control cabinet. See also under the heading "Mounting dimensions".
This cable adapter (Id.-Nr. 239 758 01) is connected to the logic unit with the HEIDENHAIN cable Id.-
Nr. 239 760 ..
For connection to the peripheral unit HEIDENHAIN offers a standard connecting cable
(Id.-Nr. 274 545 01) , length 3 m.
