CobraNet™ EV-2
Required Materials
Getting Started
Included:
The CobraNet EV-2 Development Package ships with the following materials:
• EV-2 module w/ CM CobraNet PCB
Qty. (2)
• 3’ CAT5 crossover cable
Qty. (1)
• 6 - Pin Phoenix-style audio connectors
Qty. (6)
NOTE:
In order to provide you with the latest versions of our firmware and software
development kit (SDK), we use web-based distribution for our updates. To obtain
the latest versions of documentation and software, please go to

Not Supplied:
• Two (2) ATX computer power supplies with cables are required, one for each EV-2
module. These devices are commonly available at computer retail stores.
• Audio cables.
• RS232 cables. (Not required to pass audio.)
Setup Procedure
• Using the supplied Phoenix connectors, build audio input and output cables and two
AES3 cables (if desired). These will be used to connect your audio input and output
devices to the EV-2 modules. For analog audio pin assignments, see Figure 2 or Figure 3
below. For AES3 pin assignments, see Figure 4 below.
• Connect a power supply to the ATX Power Connector at P450 on each EV-2 module.
• Connect the CAT5 crossover cable between the Ethernet jacks at J5 on each CM board.
• Connect a stereo audio source to the analog inputs at J300.
• Connect a stereo audio monitor to the analog outputs at J401.
• Apply power to both EV-2 modules.
• Verify that you have established a proper connection. See Table 1 on page 7 for Ethernet
connector LED status The LED CR710, if on, indicates that the AES3 receiver does not
detect a valid AES3 data input stream. If AES3 I/O is not being used, this can be disre-
garded. Otherwise, connect a proper AES3 signal to J700. Note that there must be a valid
AES3 input for the AES3 output to work.
