CobraNet™ Discovery (Disco) is for inspecting the CobraNet™ network and checking the status, configuration, and health of all the CobraNet devices on the network. This software is provided by Cirrus Logic. The Programmer's Reference Manual has a lot of involved information about CobraNet. Also in this manual is a guide explaining what the CobraNet Error Codes mean. This includes both the blink codes on the CobraNet Module (CM-1 / CM-2) and the codes that can be found using Disco. The MediaMatrix Firmware Directory has all versions of CobraNet firmware. Simply run this executable file to install the directory. Be sure to put it somewhere you will be able to find it later. You will need to configure Disco to find this directory in order to update the firmware in any of your CobraNet devices.
