Serial Settings
The Serial Settings part of the page includes these options:
•
Enable Port Logging: Enables the port-buffering feature, which allows you to monitor incoming ASCII serial data
in log form. The Log Size field specifies the size of the buffer that contains the log of ASCII serial data.
•
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 Connect device to be configured through the serial port
using the RCI protocol. See the RCI specification in the Digi Connect 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.
•
Enable alternate pinout (altpin): Enables or disables the altpin option, which swaps DCD with DSR so that you
can use eight-wire RJ-45 cables with modems. By default, the altpin is disabled.
TCP settings
The TCP Settings only appear when the current serial port is configured with the TCP Sockets or the Custom
Profile.The settings are as follows:
•
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. To enter non-printable characters, use these key sequences:

values
•
Send data only under any of the following conditions: Enable if it is required to set conditions on whether the
Digi device sends the data read from the serial port to the TCP destination. Conditions include:
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. Enter the string 1 to 4 characters in the Match String field. To
enter non-printable characters, use these key sequences:
Character
hexadecimal values
tab
line feed
backslash
