RS232 Interface Settings (RS232 / RS485 / FO)
These settings adapt the serial
interface of the Serial Modem to that of
the terminal device. The terminal
device may, for example, be an
operating PC or protection unit with a
serial interface (SIPROTEC
®
). These
settings apply to all possible
connections (RS232 or RS485 or FO).
The settings
Baudrate
Databits
Parity
and
Stop
bits
are adjusted to the communication
behaviour of the serial terminal device.
Under
TotalReadTimeout
, it is usually
OK to accept the default value of
100 ms.
The ideal signal throughput time can
be ascertained with the "ping" tool (see
below) or the "INet Info" dialog box.
CharDistance
(i.e. character interval)
with default value 5 ms should only be
changed in exceptional cases.
