Configuring the Digi Connect Devices Configuration Pages In the menu on the left side of the screen, the choices under Configuration display pages for configuring various features, including: Network: For configuring network communications. See "Configure Network Settings" on page 102. Serial Ports: For configuring serial ports. See "Configure Serial Ports" on page 103. GPIO: For configuring the GPIO pins. See "Configure GPIO Pins" on page 103. Security: For configuring security features.
Configuration through the Java Applet Interface 5 The Network configuration pages are returned to their initial settings, in which DHCP was selected. Refresh: Because the Java applet runs remotely, it is not always aware when device settings have been changed by other users. Therefore, it is sometimes necessary to refresh the applet to retrieve those settings. When you start the Java applet interface, all the device settings are updated and stored in memory.
Configuring the Digi Connect Devices Configure Serial Ports To configure serial ports, click the Serial Ports link. In contrast to the default web interface, the Java applet interface does not make use of port profiles to configure serial port settings. The serial port information displayed is similar to that shown when configuring serial ports using a Custom Profile in the default web interface.
Configuration Through the Command Line The Alarm List shows all the alarms that are currently defined for a device. Differences for alarm configuration in the Java applet include: Alarms can be configured to be sent as email messages only. They cannot be sent as SNMP traps. You would need to override the alarm configuration either by toggling to the default Web UI or issuing a followup set alarm command from the Command-Line Interface.
