3 Product Information
3.1 Intended Use of the Product
The EchoRing Ethernet Bridge (device) enables a timecritical and reliable wireless link
between Ethernetbased industrial protocol devices. It can be employed for:
• Replacing cablebased network infrastructure with a wireless connection in machinery,
vehicles and devices, enabling simplified infrastructure and flexible operations.
• Replacing network cables between moving structures or components in machinery,
vehicles and devices in order to reduce weight, size and use of installation space, as
well as wear and tear on network infrastructure.
ATTENTION — This radio device is intended for transmitting wireless data. It is furthermore intended to
be used for low latency and/or high reliability data communications. When using device, be mindful of the
general behavior and physics of the wireless channel. Abrupt or predictable changes in the operational
environment, such as movement of people or objects, and the presence of interfering devices, can result in
reduced wireless signal quality and failed data transmissions. Thus, when used in critical applications,
where the result of poor wireless connectivity can cause severe human injury or economic
damage, intended operations cannot rely solely on this device. A comprehensive system solution,
such as an integrated wired failsafe in case of poor wireless connectivity, must be installed and tested to
the level of intended application’s importance.

5 Webbased Configuration Interface
5.1 General Information
The Webbased configuration interface is used for configuring, deploying and reconfiguring
devices.
5.2 Set up and access Web User Interface
1. Arrange and connect a PC, the R3 Configuration Server and the EchoRing Ethernet
Bridges, intended to be in the same network or subnetwork, to the switch, according
to Figure 5I:
Figure 5I: Configuration setup
2. Power on to the R3 Configuration Server and network switch.
3. Open the PC’s network settings and configure the static IP address 172.30.1.10 and
the subnet mask 255.255.0.0.
4. Open a web browser and enter the URL http://172.30.0.1.
ATTENTION — The webbased user interface is designed for the web browsers Firefox (version 60
or newer) and Chrome (version 64 or newer). Other browsers may not support full functionality. !
5.3 Configure the Device
ATTENTION — New devices require a software update before use. Please see Section 5.5 !
1. Set up and access the Web User Interface (see Section 5.2).

Revision: 1.2
2. In Web User Interface, take a look at ”Echoring Deployment”. Connected devices are
shown in the paring view there. Click the IP address to pair all devices or click each
device to include/exclude it.
3. Click the ”Configure Deployment” button underneath to continue.
4. Please determine the MAC address of the device to be connected and enter it to the
right of the device’s (Node) IP address.
5. Capacity Factor configures the number of available transmission slots for each device,
allowing for greater data throughput, asymmetric traffic or synchronicity optimization
per device, in relation to overall network capacity (configured later).
TIP — To determine the required capacity factor for each device, analyze the traffic and corresponding
data rate that each device transmits, in relation to all devices in the network. Then portion out capacity
factors accordingly.
i
EXAMPLE — 3 devices have a combined network data rate of 200 kb/s,
1 device has 2 capacity factors = 100 kb/s,
2 devices have 1 capacity factor each = 50 kb/s each
6. Apply prioritized traffic filter (if needed) in bottom field under “Priority Traffic” by
entering the prioritized data’s Byte Index, counted from the start of the MAC header,
and its Byte Value.
i
EXAMPLE — Profinet:
EtherType
MAC header 0x88 0x92 Byte Values
|−−−−−−−−−−−−−−−−−−−−−−→ |−−−−→ |
Byte index 12 13

To filter for additional/other packet aspects, such as IP addresses, packet flags, QoS
fields or similar, add additional entries to the prioritized traffic filter.
TIP — Filter entries work as AND function, meaning data to be prioritized must match all entries.
TIP — Data to be transmitted is buffered in a queue and transmitted when its device’s transmission
slot arrives. If the application has multiple traffic types  such as critical control/safety packets or
besteffort packets  they can be prioritized via a filter. Packets matching the filter will be buffered
in an alternate queue and sent prior to packets in the main queue. If no prioritized traffic is set, all
data is treated as equally critical.
7. Click the EchoRing tab and set the parameters to match the application data and the
wireless settings.

H
AChannel: the network’s radio frequency to operate on
TIP — To prevent interference, please ensure that any other radio transmitting devices in the
vicinity of the network are not operating on the selected frequency. Please refer to our product
portfolio for tools to assist in wireless coexistence.
BTxPower: each device’s transmitting power
TIP — Some milliwatt (mW) to decibelmilliwatts (dBm) conversions are 0dBm=1mW,
10dBm=10mW, 14dBm=25mW.
CReliability: the level of reliability mechanisms activated for the EchoRing protocol
TIP — To ensure the network can facilitate the application traffic’s cycle time, packet length
and data rate, begin with setting lower reliability, then increase as necessary after all other
parameters have been set.

Value Function
1 (minimum) Minimal reliability measures, allowing for higher
throughput performance and low latency.
8 (maximum) Maximum reliability measures, often resulting in lower
throughput performance and higher latency.
DOptimize For: optimize the network for one of three parameters: Reliability (C),
Packet Length (F) or Latency (G). The selected parameter will be given best
possible value automatically pending on the other parameters input value. The
”Exact Config” option disables this function.
EBase Data Rate: is the shared data rate for all devices that is achievable on the
current setting
TIP — A Base Data Rate value can be entered as a parameter which is helpful in cases when
the required network throughput is more important than other factors like Packet Length.
FPacket Length: the maximum expected packet length, which includes all protocol
headers. An example of a packet with a UDP payload:
ER Frag
mentation
(4B)
Ethernet
(14B)
IP Header
(20B)
UDP Header
(8B)
Usable payload
(100B)
TIP — Prioritized Packets (F) that exceed the configured Packet Length will be discarded. Non
prioritized packets can exceed the configured Packet Length but will be fragmented instead.
GLatency: the time limit a transmitted packet must be received not to be dropped
HTargeted Token Rotation Time: the timespan for a station that has transmitted a
packet to be allowed to transmit once more
i
EXAMPLE — If the application traffic has a cycle time of 16 ms (whereas packets received later
than this may result in an application shutdown), the system should ideally be configured with
a Targeted Token Rotation Time of just below 8 ms, allowing for jitter leeway.
TIP — If the application’s data rate exceeds the maximum throughput limited by the other set
configuration parameters, the system overloads and the packets risk being dropped, leading
to packet losses. If application has combined traffic of both critical and besteffort, the setting
Prioritized Traffic filter (step ??) allow a type of traffic to prioritized and the other transmitted
secondly (bearing eventual packet losses).
8. Click ”Deploy Configuration” to input the configuration into the devices.
9. Power cycle the devices and disconnect from the switch.
10. Connect each device to their respective, MACaddress configured, device(s).
