Connections

AC Power Cord

Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the BASIS 922dz. Plug the AC line connector into the AC outlet. The power supply will accept from 100 to 240 Volts AC, 47 to 440 Hertz, without any changes. If a different type of IEC power cord is required than supplied with your 922dz, con- tact QSC’s Technical Services Department.

CobraNet and QSControl con- nection. Accepts ruggedized or normal shell-less RJ45 plugs.

CobraNet

Connect one end of a category-5 cable terminated with a RJ45 plug into the CobraNet receptacle. Insert the RJ45 plug into the receptacle with the lock-tab oriented toward the bottom of the BASIS 922dz and push firmly until the connector locks into place (usually an audible “click” can be heard). Connect the other end to the appropriate CobraNet network port.

AES/EBU digital input connector and pinout.

QSControl

Connect one end of a category-5 cable terminated with an RJ45 plug into the QSControl receptacle. Insert the RJ45 plug into the receptacle with the lock-tab oriented toward the bottom of the BASIS 922dz and push firmly until the connector locks into place (usually an audible “click” can be heard). Connect the other end to the appropriate QSControl.net network port.

Digital Audio Inputs

Four pair of AES/EBU inputs are provided through a DB-25 style connector. Connec- tion pin-out is printed on the rear label for reference. AES/EBU sample rate must be 48KHz and is internally synchronized.

Omni In

The six Omni In connectors are two-pin terminal block connectors. They accept contact closure, TTL logic signals, 0-5 VDC control voltages, or 10k ohm variable resistors. The contact closure and logic devices accommodate on/off or state- change events; the variable resistor input provides full 8-bit resolution allowing for incremental-change events. Refer to the illustrations for connection recommenda- tions. NOTE! +48 volts is the absolute maximum that can be applied to the + pin without damage. Voltage is with respect to chassis or the - pin.

Logic Out

The four Logic Out connectors are two-pin terminal block connectors. They pro- vide CMOS logic level compatible signals for external devices.

Relay Out

Two sets of relay contacts are provided, RELAY OUT 1 and RELAY OUT 2. Con- tacts are floating and rated for 30VDC, 1A. There is one common terminal, one nor- mally-closed contact terminal and one normally-open contact terminal. These are labeled as C, NC and NO on the rear panel. When the relay is not energized, the C terminal is connected to the NC terminal and the NO terminal is not connected; when the relay is energized the C to NC connection is opened and the C to NO con- nection is closed.

Omni In connec- tions. Variable input must be 10k ohm variable resistor. Contact closure input can be a switch or relay contacts. These inputs can operate software “devices”. Nega- tive (-) terminal is at chassis poten- tial.

Logic Out connections. Negative (-) terminal is at chassis potential.

Positive (+) terminal logic level is switched using software.
