9.2 Pin Layout and Connecting Cable for Data Interfaces
RS-232-C/V.24 Interface
HEIDENHAIN devices
The connecting pin layout on the TNC logic unit (X25) is different from that on the adapter block.
Non-HEIDENHAIN devices
The connector pin layout on a non-HEIDENHAIN device may differ consid-
erably from that on a HEIDENHAIN device. The pin layout will depend on
the unit and the type of data transfer.
