Choose the management interface you want to use to access your device. Click a dropdown for instructions.
Digi Remote Manager
1. Log in to Digi Remote Manager.
1. Navigate to the device's dashboard.
Web UI
1. Log in to your device's Web UI.
Admin CLI

Log in to your device's Admin CLI via an SSH client, Telnet client, or terminal emulator.

    The Serial Configuration or Serial page is displayed.
2. Click the name of the port that you want to configure.
3. For Mode, select RealPort.
4. Select an option from the Sharing Mode list box to determine which user(s) can change the port settings, and whether users can receive data from the port.
  - None: Only the user that opened the port can change the port settings. All other users are rejected. No other users can receive data from the port. This is the default.
  - Primary: Only the user that opened the port can change the port settings. All other users that try to open the port receive all of the data read to the port.
  - Peer: Any user that tries to open the port can change the port settings. All users that try to open the port receive all of the data read to the port.
5. (Optional) For Label, enter a label that will be used when referring to this port.
6. For Signaling, select the electrical signaling interface type used on this serial port:
  - RS-232. This is the default.
  - RS-485
    
    Enable Termination if you want to enable electrical termination on this serial port.
7. Expand Logging Settings to configure logging for this serial port.
  1. To enable logging, click to toggle on Enable.
  2. In the Log file name field, enter a descriptive name for the log file.
  3. For Log file size, type the size of the log file. When the log file reaches the size limit, the current file is saved and a new file is created. The default is 65536 bytes.
  4. Use the Enable remote logging option to enable serial data logging to remote servers. The serial data for the port is exported and sent to the remote server. The remote server configuration determines how the file is saved.
    
    Disabled: Serial data logging to remote servers is not performed. This is the default.
    
    Enabled: Serial data logging to remote servers is performed. The serial data for the port is exported and and sent to the remote server.
    
    Note When this feature is enabled, you must also have a syslog server configured for the device, which ensures that the log can be saved. To add a syslog server, click the wrench icon next to the Enable remote logging option or navigate to Device Configuration > System > Log > Server List.
