W&T Configuration of the serial port
Subject to error and alteration
2� Show Connection – The output is switched to the
serial port depending on an existing TCP connection.
HIGH (+3...12V) indicates an existing connection.
3� NO (Default=HIGH) – The outputs are not used
by the Com-Server and carry a constant HIGH level
(+3...12V).
4� NO (Default=LOW) – The outputs are not used by
the Com-Server and carry a constant LOW level (-3...-
12V).

PIN: CTS und PIN: DSR
The inputs CTS and DSR can be assigned the following
functions:
1� Flow Control – The serial flow control is performed
using the corresponding pin. Serial data are output
only if the input was set to HIGH (+3...12V) by the con-
nected terminal device.
2� OPEN/CLOSE – Connection This option for TCP
connection building and ending can be used to control
connection building and ending in all Com-Server client
operating modes. If the IP address and the TCP port
are stored in the Com-Server, a HIGH level (+3...12V)
on the corresponding input establishes a connection.
The connection is closed with a LOW level (-3...-12V).
3� Accept only by HIGH – Connection establish-
ment of a TCP client is only accepted if a HIGH level
(+3...12V) is present on the corresponding input. Li-
kewise the connection is rejected when there is a LOW
level.
4� NO (Manual IN) – The selected input is ignored by
the Com-Server.
