RS-232-C/V.24
In addition to a connection for the edge finder, the X10 socket also
provides an RS-232-C/V.24 data interface.
The data interface on your ND display unit enables you to use a printer or
a PC for transferring measured values or programs.
The interface is permanently set to the following data format:
1 start bit
7 data bits
Even parity bit
2 stop bits
The baud rate is set with parameter P50.
For connection to peripheral devices you can use either full wiring
(figure at upper right) or simplified wiring (below right).
