Pin layout and connecting cable for the data interface
The connector pin layout on the adapter block differs
from that on the TNC logic unit (X 21).
The X21 interface complies with the recommendations
in VDE 0160, 5.88 for separation from line power.
Connecting non-HEIDENHAIN devices
The connector pin layout on a non-HEIDENHAIN device may be quite
different from that on a HEIDENHAIN device. This depends on the
unit and the type of data transfer.
