RDNet Controller for 8 Lines per 256 Speakers RDNET CONTROL 8 is an hardware interface to connect dB Technologies RDNET compatible devices (DVA T12,T8, DVA S30N,etc.),  to a Personal Computer (PC) by means of an USB connection.This appliance can be used on a stand or installed in a standard 19" rack.The overall dimensions consist of a single unit; fastening is performed by 4 screws to be inserted into slots located on side flaps.RDNET CONTROL8 is an hardware interface to connect diffusers or accessory appliances to a Personal Computer (PC).RDNET system uses a proprietary serial protocol especially developed to create a data network which can remotely manage up to 256 compatible devices (ex. dBTechnologies professional diffusers such as DVAT12, DVAS30N, DVAS15N, etc.. )The interface is managed by PC through a suitable software running on Microsoft Windows® operating systems.The audio devices are connected to RDNET CONTROL 8 control unit, which performs the main function of data routing between PC and devices themselves.RDNET system allows monitoring the status of each devices, i.e. the main values to be taken (VU-meter, temperatures, logistic status, etc.).The PC cyclically requires the RDNET CONTROL 8 unit the operating state of audio devices that 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.RDNET is a "œreal-time" system: Information relating to the functioning of audio devices is acquired in real-time, feature that allows a connected devices global view.It is possible to check each single audio device and edit its parameters (e.g. output level, mute, equalisation, delay, etc.) by using the PC software.The audio device overall configuration can be saved as file in the PC and later reloaded. It is possible to synchronise all parameter values of the RDNET CONTROL8 unit to the ones of the PC software preset.The link between the PC and the RDNET CONTROL8 unit can be made through USB port (the alternative ETHERNET port will be enabled with new firmware releases, port that will be useful when the PC is far or it is necessary to link the RDNET CONTROL 8 unit to an ETHERNET net already wired).USB link shall be at least version 1.1 or 2.0, and can be used when the PC is close to the central unit (a few metres).The RDNET CONTROL8 unit can manage up to 8 subnets. Up to 32 audio devices can be connected to each subnet (8 subnets x 32 = total 256 audio devices).
