CobraNet™ EV-2

Switch and Connector Functionality

J300

Audio Input Connector: Phoenix-style connector for two-channel balanced audio input,

+14.4 dBu maximum (0 dBFS). Refer to Figure 3 for the signal connection.

J401

Audio Output Connector: Phoenix-style connector for two-channel balanced audio output,

+8.3 dBu maximum (0 dBFS). Refer to Figure 3 for the signal connection.

J700

AES3 I/O Connector: Phoenix-style connector for an AES3 stream. Refer to Figure 4 for the

signal connection. For the AES3 tranceiver to operate properly a vailid AES3 signal must be

provided at the AES3 input.

P450

ATX power supply connector: ATX power supply is not included with this kit.

P501

9-Pin, D-Type Connector: RS232 connection for communicating with the EV-2 microcontroller

using the supplied routing software or a command line interface ( see Appendix E ). Data

format is 19200, e, 8, 1.

P504

9-Pin, D-Type Connector: RS232 connection to the CM for serial bridging. The default data

format is 19200 baud, 9-bit format for the CM-1. 9-bit format supports any 8 bit format with

parity such as 19200, e, 8, 1. The default data format for the CM-2 is 19200 baud, 8-bit

format.
