INSYS ETHERNET 5.X Functions and their Configuration

Use the software-controlled data flow control only for the trans-
mission of ASCII data. If binary data is transmitted, make sure that
the control characters are not included in the data stream.

7.2.3 Echo
With echo, all commands which are transmitted to the INSYS Ethernet via the serial in-
terface are returned at the serial interface. This enables you to read the AT commands
during terminal operation.

7.2.4 DTR Behavior
The control line DTR of the serial interface indicates whether a device (configuration PC,
controller) is connected with the INSYS Ethernet and is active. The setting controls the
behavior when the DTR signal is missing, e.g. when the terminal device (PC, controller) is
disconnected.
No DTR behavior
The INSYS Ethernet does not utilize the DTR signal. This setting must be used during
stand-alone operation (I/O tunneling) or for connections with devices which do not sup-
port DTR.
Disconnect connection
The INSYS Ethernet terminates the existing connection, if the DTR signal is missing.
Reset
The INSYS Ethernet terminates the existing connection, if the DTR signal is missing and
performs a restart.
