CobraNet™ EV-2

•

Select the appropriate PC serial port. The software will attempt to make contact with the

EV-2.

•

Once communication is established, the routing can then be configured. (See Figure 5

below for an example of a routing scheme.)

The default on power up state of the EV-2 is for the ADC and DAC to be the source and sink

respectively, using the CM’s SSI #0 I/O stream. The audio is then transmitted/received via a

CobraNet Bundle to/from the other CM. This allows evaluation of the CobraNet module in the

analog domain without any configuration.

The EV-2 software also has a programming mode that may be used to perform field updates of

the EV-2 microcontroller code. For more information about the programming mode, please refer

to the section Programming the Microcontroller below.

Besides the Route panel, the HMI panel under the Panels menu allows the user to configure

some HMI variables for evaluation purposes. From the HMI panel the user can set receiver and

transmitter bundle assignments as well as changes latency, data format, and sample rate.

The Peek menu provides a means to view HMI variables. In the various panels under Peek,

items that are in an indented text field are ones which are read/write. These can not be changed

from the Peek panels but are there to alert the user that these are variables that could be

changed via SNMP or the Host port.
