[. . . ] How to use for Redundant Operation: Connect the SYNC OUTPUT to the slave unit's SLAVE INPUT. The loss of this signal to the slave initiates a fail-over event and the slaved unit becomes active. Redundant operation provides a second RAVE for audio backup in mission-critical applications. 2A 250V 20 x 5 mm FUSE (2 required) Sync connections on the rear panel of a RAVE unit SLAVE/SYNC INPUT This 50 ohm BNC female jack can be used to synchronize the network to an external clock source. The unit must be acting as the system "conductor" and the external clock must be a valid increment of the isochronous cycle clock. To implement external synchronization, the first group of front panel hexadecimal switches must be set between "80" and "FE". This provides well over 100 bundle assignments possible for use with the external synchronization feature. As with all managed features, external synchronization can be configured through the management interface using a software application implementing SNMP. How to use for Redundant Operation: SLAVE INPUT is connected to master (main) unit's SYNC OUTPUT. During redundant operation, the slave input provides the backup unit with a sample clock from the primary or master RAVE. As long as this signal is present, the slave unit will exist on the network in standby mode. In standby, all network audio communication is suspended and output relays are forced open. If the master clock is lost, the slave senses the missing clock on its slave input and commences network audio communication. The slave unit becomes enabled when the sample clock is missing from its SLAVE INPUT. 16 Connections: Sync Connection for Redundant Operation, RS-232 Port Rear panel coax cable and Ethernet connections REDUNDANT CONFIGURATION (hardware setup) To slave one RAVE unit to another, connect a male-to-male BNC jumper cable from the sync output of the master unit to the slave input of the redundant unit. Select the same bundle assignment(s) on the slave unit as are selected on the master unit. Bundle assignments and additional parameters available for redundant operation may be configured through MI variables Configuration example for redundant audio transmission Note that audio connections must be present at both devices. This may be accomplished through the use of "Y" connections or by channel duplication from a console or other source device. via SNMP. Refer to the Peak Audio and QSC Audio websites regarding additional methods for redundant and fail-safe operation on switched Ethernet LANs. RS-232 PORT The RS-232 port is an auxiliary interface which serves two primary functions. It provides a serial method for upgrading the CobraNet program code and it provides a means to bridge serial data onto Ethernet. The serial bridge allows the user to transmit serial data over the network, from one RAVE unit to another. This is a handy feature for remotely controlling and/or programming accessories and processors that require an RS-232 serial interface. The serial data format is optimized for RAVE at 19, 200 baud, 9 bits (or 8 bits w/ parity), 1 stop bit. All attached stations receive these broadcasts and transmit the data simultaneously out their respective serial ports. [. . . ] To use as Slave: connect to Master via coax cable Sync, then duplicate hexadecimal switch settings (see pages 16 and 17). MISC.

There are only two likely situations that would require a crossover cable: to connect two RAVE devices directly, without a repeater or other device in between; and to cascade repeaters or switches that don't have uplink ports.
