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 section "Cable overview".
For connection to the peripheral unit HEIDENHAIN offers a standard connecting cable
(Id.-Nr. 274 545 01), length 3 m.
