7.4 RS-232 interface parameters
Normal/secured
Secured transmission is set in conjunction with the RTS/CTS
Handshake for the selected interface. "Normal transmission" is the
default setting.
The protocol setting is addressed in:
· Data input/output
· Series installation and startup/upgrade
in conjunction with RS-232 or PG.
SinuCom PCIN software is required on the external PC/PG as
partner.
Input: By selection in display "Interface" under "baud rate" with the
selection key
300 baud
600 baud
1200 baud
2400 baud
4800 baud
9600 baud
19200 baud (default)
:
115200 baud
A baud rate of up to 115 kbaud can be set. The usable baud rate
depends on the connected device, cable length and electrical
environmental conditions.
Number of data bits for asynchronous transmission.
Input: By selection in display "Interface" under "Data bits"
· 7 data bits
· 8 data bits (default)
Parity bits are used to detect errors:
The parity bits are added to the coded characters to make the number
of places set to "1" an odd number (odd parity) or an even number
(even parity).
Input: Selected in the "Interface" display under "Parity"
· No parity (= default)
· Even parity
· Odd parity
Number of stop bits for asynchronous transmission.
Input: Selected in the "Interface" display under "Stop bits"
· 1 Stop bit (= default)
· 2 Stop bits
