Change the signaling mode

To change the signaling mode:

 

  Web

  1. Log into Digi Remote Manager, or log into the local Web UI as a user with full Admin access rights.
  2. Access the device configuration:

    1. Locate your device as described in Use Digi Remote Manager to view and manage your device.
    2. Click the Device ID.
    3. Click Settings.
    4. Click to expand Config.

    1. On the menu, click System. Under Configuration, click Device Configuration.

      The Configuration window is displayed.

  3. Click Serial > Port 1.
  4. For Electrical signaling mode, select the appropriate signaling mode.

  5. Click Apply to save the configuration and apply the change.

  Command line

  1. Select the device in Remote Manager and click Actions > Open Console, or log into the IX40 local command line as a user with full Admin access rights.

    Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.

  2. At the command line, type config to enter configuration mode:

    > config
(config)>

  3. Set the signaling mode:
    (config)> serial port1 signal_mode value
(config)>

    where value is one of:

    • rs-232

    • rs-422

    • rs-485

    If this is the end device along a cabled RS-485 daisy chain and termination resistors are recommended, enable an internal electrical termination:
    (config)> serial port1 termination true
(config)>
  4. Save the configuration and apply the change.
    (config)> save
Configuration saved.
>
  5. Type exit to exit the Admin CLI.

    Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.
