Operation

 QSControl Port

The QSControl port operates on a 10BaseT Ethernet network. This port is one of the primary means for connecting QSControl.net to the 
BASIS. The port may connect directly to a PC's 10BaseT or 10/100 (auto-sensing or auto-negotiating) network interface card using a 
crossover cable. Data from the QSControl port may also pass through network repeaters, network switches and routers. We strongly 
recommend the use of network switches to facilitate higher bandwidth and dedicated connections. 

CobraNet Port

The CobraNet port operates on a dedicated 100BaseTx (Fast Ethernet) network. The CobraNet port may connect directly to a PC's 
100BaseTx or 10/100 (auto-sensing or auto-negotiating) network interface card using a crossover cable for the purposes of configura-
tion when the BASIS 922az is in the single-wire interface mode. During normal operation (passing audio) the CobraNet port must con-
nect to a 100BaseTx or 10/100 or 10/100/1000 (auto-sensing or auto-negotiating) switch port. Optionally, the BASIS 922az may connect 
to another CobraNet port using a crossover cable. When the BASIS 922az is operating in the two-wire interface mode (described in fol-
lowing sections), the CobraNet port may be connected to a network repeater. Regardless of the interface mode, all CobraNet audio data 
must pass through only network switches or only network repeaters. Combinations of these devices will cause unreliable operation and 
are not supported. Likewise, the use of routers, gateways and ATM devices are not supported for the CobraNet audio path. 

CobraNet Channel Density

The BASIS 922az will support the acquisition of up to 32 channels via up to 4 inbound bundles (from the network). Of these 32 channels, 
any 16 may be selected to forward to the signal processing chain (DSP engine). 
The BASIS 922az will support the delivery of up to 32 channels via up to 4 outbound bundles (to the network). Of these 32 channels, up 
to 24 may be unique (processed individually... or the result of mixed signals from the DSP engine). The remaining 8 channels (if used) 
will be copies of other channels. 

CobraNet Channel Resolution

All CobraNet audio will be processed internally within BASIS 922az at 24-bit resolution. The BASIS 922az may receive any valid resolu-
tion off of the network. This is currently 16-bit, 20-bit and 24-bit. Audio via inbound bundles may be in any combination of these resolu-
tions and the BASIS will process the data accordingly. All DACs will process 24-bit audio, though the least significant bits may be zero 
filled if the inbound audio format is less than 24-bit resolution. 
The BASIS 922az will support outbound (sourced onto the network) resolutions of 16-bit, 20-bit and 24-bit. The default outbound reso-
lution is 20-bit.

CobraNet Terms and Conditions 

Single-wire interface

 offers the best efficiency and ease of network configuration for most applications. The single-wire interface 

requires fewer network ports and less cabling. Single-wire interface refers to CobraNet audio, CobraNet control and monitoring and 
QSControl.net control and monitoring using the same network connection. This mode uses the CobraNet connection to provide all data 
communications to the BASIS product. In this mode, the port must connect to a 100BaseTx or 10/100 or 10/100/1000 (auto-sensing or 
auto-negotiating) link partner. Network repeaters will not be supported and all audio must pass through network switches only. A 
QSControl Venue Manager PC may connect to the network via a repeater or router.

Two-wire or dual-wire interface

 offers the greatest versatility in network design. Separate connections allow discrete networks 

and offer support for WAN topologies on the QSControl.net-side. Two-wire or dual-wire interface refers to CobraNet audio having a 
dedicated network link and QSControl control and monitoring having a dedicated network link. In this mode, the two ports (CobraNet 
and QSControl) must be connected to separate networks. By separate networks, we mean either physically separate hardware or the 
use of common hardware with partitioned or segmented network domains such as the use of VLANs, domain bubbles or separate port 
clusters. The dual-wire interface may support dissimilar network hardware for the two port connections (see rules above for CobraNet 
and QSControl port connections).

Scratchpad 1 Minute Timer and Power Cycling 

The active, current running configuration has a special feature associated with it. Any change to a parameter made at run time is stored 
to a scratchpad area of the device after one minute without additional change. If the BASIS 922az is then power cycled, the scratchpad 
settings will be restored, thus ensuring the BASIS starts up with the same settings it had when powered down. Additionally, QSCon-
trol.net will notify the user that the running settings are stored in the scratchpad, rather than in the flash configuration.
