TNC 407/TNC 415/TNC 425 2 TNC data interfaces 8-17
These signals perform the same functions as those on the RS-232-C/V.24 interface.
The transmission protocol is absolutely identical for the RS-232-C/V.24 and RS-422/V.11 interfaces.
In addition, the protective earth connects the transmitter and receiver casings. The signal GND
represents the differential voltage reference conductor.
2.3.4 Pin layouts
On the TNC 407/415, the following pin layout is adopted at the logic unit and adapter block (see the

2.4 Data interface functions
The data interfaces on the TNC can be used to save data and files and read them back in again, to
output programs to external devices (e.g. printers), to read in programs and simultaneously execute
them and to carry out data transfer (communication) between TNCs.
