Summary
DescriptionRS232 Oscilloscope Trace K-7E1.svg
English: Diagram of RS232 signalling an uppercase "K" character as seen when probed by an Oscilloscope. The RS232 electric signalling uses active low (negative logic). The digital data representing "K" (0x4b) as 7-bit ASCII is framed as "7E1" with 1 start bit, 7 data bits, even parity,1 stop bit.
Deutsch: Das Diagramm der RS232-Signalisierung zeigt ein großes „K“, wie es bei der Abtastung mit einem Oszilloskop zu sehen ist. Der Logikpegel der RS232-Signalisierung ist low-aktiv (negative Logik). Die digitalen Daten, die „K“ (0x4b) als 7-Bit-ASCII darstellen, werden als „7E1“ mit 1 Startbit, 7 Datenbits, gerader Parität und 1 Stoppbit dargestellt.
RS232 signalling as seen when probed by an actual oscilloscope (Tektronix MSO4104B) for an uppercase ASCII "K" character (0x4b) with 1 start bit (always), 8 data bits, 1 stop bit and no parity bits (8N1)
