2. CobraNet DISCOVERY
The CobraNet Discovery Software (also referred to as 'Disco') should be downloaded and installed. Disco
provides the following indispensable functions:
• Discovers and displays all CobraNet devices on the network.
• Provides a user configurable watch window to monitor device health.
• Provides a firmware update function.
• Assigns IP addresses to CobraNet devices. CobraNet device IP addresses are dynamic by default.
A CobraNet interface will not have an IP address when powered up. Disco is used to automatically
or explicitly assign IP addresses when needed.
• Provides a GUI interface for changing commonly used configuration variables.
• Provides an advanced interface for changing or monitoring any CobraNet variable via SNMP.
• Provides a report generation function useful for documenting configuration and troubleshooting.
Read the CobraNet Discovery manual that is installed with the program.
3. FIRMWARE
It is important to select the correct Firmware when updating the CobraNet Flash memory as the Firmware
needs to match the actual hardware.
