CobraNet Signal Routing
CobraNet devices transmit and receive digital audio (48 or 96 kHz, 16, 20 or 24 bit) in bundles of up to 8 channels. The number of chan-
nels per bundle can vary, depending on settings for latency and resolution. The number of bundles available depends on network band-
width.
Each CobraNet bundle has a number from the following ranges:
0: Disables the receiver or transmitter.
1 thru 255: Multicast mode (many receivers can access the same bundle).
256 thru 65,279: Unicast mode (allows only one receiver to receive the bundle).
In order for CobraNet devices to communicate,
their Tx (Transmit) and Rx (Receive) bundle
numbers must match. RHAON devices are
equipped with two receivers and two transmit-
ters, their bundle numbers must be assigned
correctly so they can send and receive audio via
the network. RHAON software makes this easy.
In most cases the settings of a CobraNet source
will have already been established with the
source’s own proprietary software and can be
changed only with the manufacturer’s software..
However, it the manufacturer’s software allows
you can set or reset both receiver and transmit-
ter bundle settings of any device found on the
CobraNet network using RHAON software.
The first step in setting up CobraNet routing is
to drag the CobraNet Source that was detected
by Scan Network into the system.
The CobraNet Source and the devices connect-
ed to it must have the same Sample Rate and
Latency settings. Right clicking on the CobraNet
Source Icon will open a pop up screen showing
the Sample Rate and Latency settings. We sug-
gest you accept the Source’s default settings
unless you have a specific reason to change
them.
You will then want to check the device settings
to make sure they are the same as the Source’s
settings. The settings must be the same for the
source and for all devices connected to it.
While latency may be changed here via point-
and-click, the sample rate is pre-programmed
in the DSP firmware running in the loudspeaker.
You can switch sample rate by uploading the
appropriate firmware to your device. Please
refer to “APPENDIX III: Updating DSP Firmware” for information on how to upload new firmware to your device.
Next, check the bundle settings of the CobraNet Source device. The Source in our example has 4 Receivers and 4 Transmitters. The red
triangles on the left of its icon represent Rx bundles and the green triangles represent Tx bundles. Right clicking on one of the triangles will
open a pop up window that shows the bundle number and allows you to change it.
