CobraNet Network
Connect one end of a data communications cable terminated with an RJ45 plug into the CobraNet
™
Primary
receptacle on the rear panel of the DXP product. Ensure that the lock tab on the cable engages with the RJ45
receptacle on the rear panel DXP connector. For systems requiring redundant network connections, connect a
second data communications cable terminated with an RJ45 plug into the CobraNet
™
Secondary receptacle on the
rear panel of the DXP product.
NOTE:
Data communications cabling must be rated CAT-5 or better for all CobraNet
™
connections.
Automation Inputs
The automation inputs use a 2-terminal Euro style (a.k.a. Phoenix) receptacle. The Automation Inputs can be connected to relay contacts or a switch
and require a 2-terminal Euro style plug. The DXP rear panel label provides all necessary signal information. The negative terminal of each receptacle is
at chassis potential.
Relay Outputs
Four relay outputs are provided via two 3-terminal Euro style (a.k.a. Phoenix) receptacles. Relay contacts are fl oating
and rated for 30 VDC at 1A. Each output includes one common terminal, one normally open contact (NO), and one
normally closed (NC) contact. These terminals are labeled C, NO and NC, respectively on the DXP rear panel. When
the relay is not energized, the C terminal is connected to the NC contact and the NO contact is not connected. When
the relay is energized, the C terminal is connected to the NO contact and the NC contact is not connected.
DataPorts
QSC DataPorts on the DXP rear panel are intended to interface to QSC amplifi ers with v1 DataPorts. These are the
all-capable DataPorts, which are included on DCA and PL3 series amplifi ers. All DataPorts use the HD15 connector
format and connect to QSC amplifi ers via data communications cables having male HD15 connectors on both
ends. These are commonly referred to as VGA cables. To connect a DataPort cable between a DXP DataPort and an
amplifi er DataPort, attach the cable’s male connectors to the HD15 ports and fi nger tighten the thumb screws on
the connectors.
NOTE:
Although many off-the-shelf VGA cables may work with satisfactory results, the QSC DataPort
specifi cation requires that all conductors be present and that all audio I/O conductors be shielded.
Therefore, only QSC supplied DataPort cables should be used. A variety of lengths are available
through QSC’s Technical Services Group.
Mic/Line Input
A single Mic/Line Input is accessible on the DXP rear panel. This input can be used for mono non-sync sources or for
connecting a microphone for local paging or announcements into the auditorium or to support various corporate or live
events requiring a microphone. Phantom power may be enabled via DCP Manager™ confi guration or via the DXP front panel
interface. The Mic/Line Input uses a standard 3-conductor XLR receptacle.
NOTE:
The Mic/Line input uses standard XLR cables that are readily available through retailers specializing in
musical equipment, pro audio or home electronics.
