R70 Ethernet to CAN interface d&b audiotechnik GmbH
1. R70 Ethernet to CAN interface
This manual describes the facilities and functions of the hardware and
the basic operation of the R70 Ethernet to CAN interface.
Basic knowledge of Ethernet network technology is assumed.
A detailed description of the advanced functionality of the R70 is given
in the 'Software reference manual' which is available on the attached
CD-ROM in English language.
1.1. General safety instructions
Installation and start up must only be carried out by qualified
technicians.
In case of a malfunction or doubts concerning the proper functioning of
the device, please contact d&b audiotechnik for further information or
advice.
As the device does not contain any components to be maintained or
repaired by the user, the enclosure must not be opened. The device can
only be repaired by d&b audiotechnik.
1.2. Intended use
The R70 Ethernet to CAN interface provides two RJ 45 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.
A detailed description of the d&b Remote network (CAN-Bus) is given in
the technical information TI 312 which is provided with the CD-ROM or
can be downloaded from our website at www.dbaudio.com. We
recommend to regularly check the d&b website for the latest version of
the documentation (R70 manual and TI 312).

[DC IN]
The device can be powered by Ethernet (PoE, IEEE 802.3af) or by an
external power supply according to the specifications.
The connector for the external power supply is located on the right
hand side panel of the device (DC IN/Center Positive Standard
).
The power supply is equipped with changeable AC input plugs to allow
for connection to the following mains sockets: Europe, UK, USA, and
Australia.
Fitting/Exchanging the AC input plug
To fit or exchange the AC input plug, proceed as follows:
1. Slide in the respective AC input plug until it snaps into place.
2. To exchange the plug, press the button [B] and slide out the
plug.

Two RJ 45 connectors are located on the left hand side panel of the
device. Both connectors are wired in parallel to allow different wiring
setups of the CAN-Bus
NOTICE: Shielded cables and shielded RJ 45 connectors must be used
to connect the devices of the d&b Remote network (CAN-Bus). The
cable shielding must be connected to both sides of the RJ 45 connector
as the "CAN Ground" is routed via the cable shielding.

In general, the CAN-Bus has to be terminated on both ends of a CAN-
Bus segment. Please refer to the technical information TI 312
d&b Remote network for more detailed information.
The R70 interface has a built-in switchable terminator which can be
activated when only one of its CAN connectors is used (refer to the
wiring examples given in the following section).
To terminate the interface:
•Set the termination switch [3a] to TERMINATE. The corresponding
status LED [3b] lights up.
In this case both RJ 45 connectors are terminated as shown in the
graphic opposite.
Note: The two RJ 45 M terminators supplied with the R70 interface
must not be used to terminate the interface if the termination switch is
set to TERMINATE. They are used to terminate the last device of a
CAN-Bus segment (refer to the following section).

2.2.2. Indicators (Status LEDs)
The R70 interface is equipped with four LEDs for visual status control of
the device. The function of each LED is described in the table below:
[4] [5] [6] [7]
LED (Col. [Pos.]) Status: Description
LAN (Green [4]) Off: No active Ethernet connection
Rapid flashing: Active Ethernet connection
ERR (Red [5]) Off: No error
On: Device is in Bus off mode
Flashing: CAN error
CAN (Green [6]) Off: No CAN data transfer
On: Operational state
Slow flashing: Stopped state
Flashing: CAN message received
(through an active Ethernet
connection)
ON (Green [7]) Off: Device is shut off
On: Status OK
Flashing: Initializing
2.2.3. RESET [R]
[R]
The RESET switch (push button) is located on the right hand side panel
of the device and allows for a reset of the device to factory default. To
reset the device, proceed as follows:
1. Disconnect the power from the device.
2. Press and hold the reset switch while reconnecting the power
and continue pressing down the reset switch for approx 3 s.
During this time the reset is executed while the ERR-LED is
flashing and the CAN-LED lights up. After successful reset all
status LEDs light up.
3. Release the reset switch.

connection
Power
supply
Note: When Power over Ethernet (PoE) is available, the external
power supply is not required.
3.2. IP address
In order to access the d&b Remote network, the R70 interface must
have the same IP network settings as your network. Depending on the
network topology, the IP address can either be assigned manually or
automatically (DHCP).
When the R70 is connected to a network with a DHCP server present, a
matching IP address is assigned to the interface automatically.
In all other cases the R70 must be adapted manually.
The R70 IP address is set to 192.168.1.70 by factory default
(see also the label sticker on the rear panel of the R70).
3.3. Direct connection
To access the R70, manually assign an IP address to the PC on your
network with the same subnet as the R70. Proceed as follows:
1. From the "Start-Settings" menu select the "Network
Connection" associated with your network adapter.
2. Select "Internet Protocol (TCP/IP)" and click on "Properties".
3. Enter a static IP address in the same subnet as the R70 by
selecting "Use the following IP address":
IP address: 192.168.1.71
Subnet mask: 255.255.255.0
4. Apply the changes by clicking OK and close the network
properties dialog.
To display the web interface of the R70, enter the IP address of the R70
in the address bar of your web browser.

3.4. LAN network with DHCP server
Note: If a firewall is active, allow access to the UDP Port 33333 (fix)
and the TCP Port 30000 (adjustable).
The "Obtain an IP address automatically" function is enabled by default.
1. Connect the R70 to your network and an IP address is
assigned by the DHCP server.
2. Start the respective d&b software (e.g. R1 - Edit mode) and
select "CAN" from the "Extras-Options" menu.
The program scans for connected interfaces and all devices
found are listed. This may take several seconds.
3. Right click on an R70 entry in the list and select
"Configure Interface" to access the R70 web interface.

R70 operation and configuration d&b audiotechnik GmbH
3.5. LAN network without DHCP server
When the R70 is connected to a network without DHCP server, the R70
must be adapted to the local network.
To do so, first proceed as described in the previous section (Direct
connection) to gain access to the R70.
1. Select the "LAN Parameters" tab from the R70 web interface and
disable "Obtain an IP address automatically".
2. Enter the desired Host name, the respective IP address and Subnet
mask.
3. Click Save to confirm and execute a Device Restart.
