CobraNet Discovery (“Disco”) is a monitoring, troubleshooting and maintenance tool for CobraNet networks. Disco runs on Windows (XP, Vista and 7) computers and uses the standard Ethernet network interface (NIC) to connect to and observe a CobraNet network. CobraNet devices on the network are discovered and enumerated in the application. Critical performance parameters are retrieved from the devices and displayed. Devices can be selected and over-the-network firmware upgrades initiated from the application.
