CobraNet™ EV-2
• Routing flexibility: Route from any audio source to any audio sink using the supplied EV-2
software. Route to and from the CM as well as within the EV-2.
• Sine wave generation: A sine wave test tone may be used as an alternate audio source.
Minimal frequency and gain control is provided.
• Hex switches: Four hex formatted switches may be used for network identification of the
CobraNet module and/or user development.
• Command line interface: The 8051, via its RS232 serial interface, can be used to
configure the CM using a command line interface.Cobranet HMI variables can be viewed
and modified using this interface. Refer to Appendix E for a description of the Command
line interface.

• Power supply: Uses standard computer ATX power supply (not included).
*The EV-2 has gone through a hardware revision to incorporate state-of-the-art A/D and D/A
converters from Cirrus logic. The new revision board is identified by a “Rev. E” designator.
Most of the changes in this document relate to the new converters and their functionality. Any
other changes which differ from the Rev. D board will be identified as such.
