Product Overview

The R70 Ethernet to CAN interface provides two RJ45 CAN connectors with a built-in switchable terminator as well as a LAN connector. The R70 contains a web interface for configuration using a standard web browser. Up to five R70 interfaces in TCP/IP mode may be connected to a PC and simultaneously operated by the R1 software.

The R70 is designed to connect the d&b Remote network (CAN-Bus) to a PC via Ethernet (TCP/IP or UDP/IP). The R70 must only be used within a d&b sound reinforcement system. The device can be used within applications according to the standard EN 60849 (IEC 60849) 'Sound Systems for Emergency Purposes' (voice evacuation systems).

The device is not intended for direct connection to telecommunication networks.

Applications

Features

The d&b Remote network enables central control and monitoring of a complete d&b loudspeaker system from anywhere in the network, be it from a PC in the control room, at the mix position, or on a wireless tablet PC in the auditorium. This central access to all functions, controls and detailed system information unlocks the full potential of the d&b system approach. It effectively speeds up the execution of various tasks during configuration and offers significant advantages during operation. Extensive monitoring and diagnostics enables detailed examination of the system performance. Control can be undertaken on individual loudspeakers, on multiple groups of loudspeakers or formed into groups that address the complete system. The flexibility and scalability of this approach, coupled with the inclusion of several types of interfaces, allow the d&b Remote network to be deployed to address the differing control and monitoring requirements in a broad variety of mobile and installed applications, regardless of their size. Every d&b amplifier is fitted with a Remote interface for the Controller Area Network (CAN) bus. Each D6 and D12 has two REMOTE connectors (RJ 45) to enable the CAN-Bus signal to be daisy chained through them. A simple d&b Remote network application consists of a computer running R1 Remote control software, an R60 USB to CAN interface, CAT 5 shielded twisted pair cable with shielded RJ 45 connectors and d&b D6 or D12 amplifiers. Up to five R60 USB to CAN interfaces can be operated with one computer running R1, while a maximum of 504 amplifiers can be incorporated into one application. The maximum bus cable length of a d&b Remote network is 600 metres. The R70 Ethernet to CAN interface can be used for applications over longer distances, in conjunction with a fibre optic network for example.
