Chapter 6: Configuring the Serial Server Properties

If Paired Mode is not being used, do not change this setting until the application has been tested and is communicating properly. Then activate the address filtering feature.

NOTE: Refer to Section 2.3.3, Paired Mode.

Update/Save

Server properties must be updated separately for each serial port. Updating varies slightly, depending on which of the four configuration user interfaces are used.

Updating the Server Properties in Serial Server Manager

From the Server Properties screen, click the “Update” button to store the configuration settings for the currently selected port. The vcomui dialog box will appear, indicating you must restart the device before the new settings will take effect. Click “Yes.” After several seconds, a dialog box will ask whether you want to search for all reachable servers again. Click “Yes.”

After that port has been updated, you may want to re-enter Server Properties to verify the changes have taken effect, or to view/ change the configuration of other ports. Each port must be configured separately.

Saving Configuration Data in Console Mode or Telnet

Saving (updating) server properties is done from the Configuration screen. Access the Configuration screen by tabbing through the list of screens on the left side of the window and highlighting Configuration.

There are four options shown on the right side of the Configuration screen: Save, Default, Running, and Reset. Use Tab, Backspace, or arrow keys to move the cursor to the option position, and then press “Enter.”

•Save stores the configuration data to the Serial Server flash memory and resets it.

•Default restores the configuration data to factory default settings.

•Running restores the configuration data to the last values stored in the flash memory.

•Reset re-boots the Serial Server, making it available for a client connection.

Web Server Interface

•The Web Server interface provides the same updating options as Console Mode and Telnet. These are located at the bottom of all three Web Server pages. If a field is changed, you must click “Save” before leaving that page, or the changes will be ignored.

NOTE: If you leave any Web Server page without saving, any changes you have made will be ignored.
