TNC 407/TNC 415/TNC 425 9 Data interface 3-41
9.2 RS-422/V.11 data interface
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".
The cable adapter is connected to the logic unit with a HEIDENHAIN connecting cable.

The pin assignment is the same at both ends of the connecting cable.
In the RS-422 adapter the pins of the female connectors are connected one-to-one.
The pin assignment in the cable adapter is therefore the same as in the X22 connector in the logic
unit.
The following cable type must be used for the connection to the peripheral unit:
LIYCY 7 x 2 x 0.14 Cu
For the cable connection HEIDENHAIN offers a 15-pin D-subminiature connector
(Id.-Nr. 243 971 ZY).
