Whirlwind PXP-CE Installation guide

INTRODUCTION
The Whirlwind PXP products are unique devices for converting digital audio data from one format to
another.Eachdevicecaninterpretthedigitalaudioreceivedonitsinputandtransmitthedataonanother

Setupandoperationare simple and easy.Justconnecta CAT5ecablefromtherespectivenetworkto the
proper RJ45 jack of the PXP and use the manufacturer's software to manipulate the routing of the digital
audio channels. The PXP-CA also has bundle select wheels to assign the desired receive bundle
numberswithouttheuseofacomputer.
FEATURES
• Communicate directly from one digital protocol to another.
• All digital signal exchange prevents any degradation of signal quality.
• Using the PXP saves valuable accessory card slots in digital consoles.
• Connections made with CAT5e cables.
• Efficient single rack space design.
• Integrated universal power supply for 100-250VAC, 50/60Hz operation.
The PXP-CAis configured with CobraNet as the input. The CobraNet digital audio signal is converted to
Aviom'sA-Net Pro-16, which is output to interface withA-Net enabled equipment. Sixteen channels of
digital audio can be converted through each PXP-CA device. Connections to each network are made
throughCAT5ecable.
On the CobraNet side, Bundle Select encoders are used to select the bundle numbers to be received by
the PXP-CA. Two bundles of 8 channels each can be received. The encoders set the number for the first
bundle,thesecond bundle isthensettothatbundle plus1.So,settingtheencoders to00300willresultin
the first bundle being 300, and the second bundle being 301.All 65,279 CobraNet bundles are directly
accessiblefromtheencoders.Bundles1-255areMulticastbundlesand256-65,279areUnicast.Bitwidth
andlatencysettingsareautodetectedfromthetransmittingdeviceanddonotneedtobesetonthePXP.
The leftmost encoder also has 3 special functions. With the encoder in the 7xxxx position, the three front
panel LEDs will flash a code for the software version in the PXP. The LEDs will blink the number of the
software version with a long pause between the series of blinks; e.g., four flashes followed by a long
pause equals version four. Should the PXP ever need to be rebooted, the 8xxxx position of the encoder
will cycle a reset of the unit every two seconds. Unplugging and reconnecting the power cord will also
reset the PXP. The 9xxxx position of the encoder is a self test for all the LEDs except the power LED.
Setting all encoders to 0 allows remote setting of bundle parameters through the network with CobraNet

POWER DATA FOR ALL PXP MODELS
Power inlet is a standard IEC connection. The power supply is internationally universal with a voltage
range of 100 to 250VAC at 50 or 60Hz.
Power LED illuminates when AC power is applied to the unit and the unit is operating.

MODEL PXP-EA
The PXP-EA is configured with EtherSound as the input. EtherSound digital audio is converted to
Aviom'sA-Net Pro-16 format, which is output to A-Net enabled equipment. Sixteen channels of digital
audio can be converted through each PXP-EAdevice. Connections to each network are made through
CAT5e cable. Configurations, parameter settings and channel routing for EtherSound are

to warn the user that persistence is enabled through CobraNet Discovery v3.4.4 and that
changing the encoders from 00000 will defeat Disco control at the next power cycle.
Persistence enabled means that the unit will remember its last settings through power
cycling.
