 Enable RTS Toggle: When enabled, the RTS (Request To Send) signal is forced
high (on) when sending data on the serial port.
 Enable RCI over Serial (DSR): This choice allows the Digi device to be
configured through the serial port using the RCI protocol. See the RCI
specification in the Integration Kit for further details.
RCI over Serial uses the DSR (Data Set Ready) serial signal. Verify that the
serial port is not configured for autoconnect, modem emulation, or any other
application which is dependent on DSR state changes.
TCP Settings
The TCP Settings are displayed only when the current port is configured with the TCP
Sockets or the Custom Profile.
 Send Socket ID: Include an optional identifier string with the data sent over the
network. The Socket ID can be 1 to 256 ASCII characters. Non-printable
characters can be entered as follows:
 Send data only under any of the following circumstances: Enable if you need to
specify the conditions when the Digi device server will send the data read from
the serial port to the TCP destination.
 Send when data is present on the serial line: Send the data to the network
destinations when a specific string of characters is detected in the serial data.
