CobraNet Evaluation Kit

CobraNet® technology has established itself as the product of choice for multi-vendor networked audio. The EV-2 provides a means of easily evaluating CM-2 CobraNet modules. It also provides an example CobraNet interface and can be used as a development platform for CobraNet products. The EV-2 comes standard with CM-2 modules but will work equally well with CM-1 modules if needed. The EV-2 Evaluation/Developers kit is available for purchase, after entering into a CobraNet nondisclosure agreement. For additional information on how to obtain the EV-2 kit or CobraNet licensing information, please contact your local Cirrus Logic sales representative. The EV-2 evaluation/developers kit includes two EV-2 boards, one Ethernet cross-over cable, two CM-2 CobraNet modules and one software CD.
