TNC 416/TNC 406/TNC 306 Data interface 3/99
9.2 RS 422/V.11 data interface
The RS-422/V.11 data interface is only integrated in the logic unit LE 416 and LE 406. It is
designated to control the generator.
If used correctly, the RS-422/V.11 serial data interface will ensure error-free data transmission up to
a distance of 1000 m between logic unit and 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" and
“Cable Overview”.
The cable adapter Id.-Nr. 249 819 01 is connected to the logic unit with the HEIDENHAIN
connecting cable Id.-Nr. 250 478 ..
