1 RDNET PROTOCOL OVERVIEW
1.1 Network description
RDNet system uses a proprietary serial protocol purposely developed by dB Technologies to create a data
network which can remotely manage up to 256 compatible devices (ex. dB Technologies
professional speakers such as DVA T12, DVA S30N, DVA S1521N, etc.. ).
The interface is managed by a PC through the DVA Network software.
The audio devices are connected to RDNET CONTROL 8 or CONTROL 2 control units, which performs the
main function of data routing between the PC and the speakers.
RDNET system allows monitoring the status of each device, i.e. the main values to be taken (VU-meter,
temperatures, logistic status, etc.).
The PC cyclically requests the RDNET CONTROL unit the operating state of audio devices, which make up
the communication network.
All data are collected by the central unit that performs a sequential scan of all audio devices.
Digital address allocation is automatic.
It is possible to check each single audio device and edit its parameters (e.g. output level,
mute, equalization, delay, etc.) by using the software.
The audio device’s overall configuration can be saved as a file in the PC and later reloaded.
1.2 Connection topology
The link between the PC and the RDNET CONTROL unit can be made through a USB or Ethernet Port
(available only on CONTROL 8).
USB link can be used when the PC is close to the CONROL unit (just a few meters).
RDNet CONTROL units can manage up to 2 subnets
(CONTROL 2) or 8 subnets (CONTROL 8).
Up to 32 audio devices can be connected to each
subnet.
This means that 256 audio devices can be connected
to Control8 and 64 audio devices can be connected
to Control 2.
Using Ethernet interface it is possible to connect more
than one CONTROL 8 unit to the same PC.
These features virtually extend to infinite the number
of devices that can be connected to the network.
