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.
