Support FAQ
Perhaps your question is already here?
Setup
-
Should EchoRing devices be shut down before a power cycle?No, direct power cycling is safe for EchoRing devices. That said, please ensure the "Successful Deployment" notification appears in the Health Monitor before resuming operations.
-
What is the recommended transmission power for an initial EchoRing desktop test?
We recommend a transmission power of ~6dBm for desktop tests.
-
Is the Configuration Server required to operate an EchoRing network, after it has been configured?No, it is no longer required. Configuration settings are stored on each Bridge E device and automatically launch the configured network upon startup.
Configuration
-
What is the recommended "Optimize For" setting?
Selecting "Exact Config" within "Optimize For" disables system optimization. This action highlights the impact of any configuration changes that are made in the "Achievable Configuration" table on the right of the interface.
-
What does the "Latency" parameter affect?
This setting limits possible configurations to only those that can meet its set latency. Priority packets exceeding this threshold will dropped in favor of newer packets.
-
Is it possible to specify a Capacity Factor of 0 for a station not actively sending signals, i.e. a Relay node?
Not currently - this feature will become available with a future software update. Until then, the minimum Capacity Factor for inactive nodes is 1.
-
It seems the Configuration Server provided my laptop with a different IP than 172.30.1.10. Can this IP be used instead?
Yes, a R3 Configuration Server runs a DHCP server. The provided IP can be be used instead of 172.30.1.10
-
Does it ever make sense to disable EchoRing's "Relay" setting?
The "Relay" setting should always be enabled so to take advantage of an EchoRing network's spatial diversity. With this feature disabled, a network can only rely on temporal diversity to resend a packet from the transmitting station, which increases latency beyond acceptable limits for critical industrial controls. Further details can be found here.
Diagnosis
-
I connected two stations in the Perfomance Analyzer with a "double arrow" link. Why am I now seeing two packet streams?
A single arrow represents a single periodic packet stream from a sender to a receiver. The receiving station will then answer each of these packets with a packet of the same size. When a double arrow is displayed, both stations send their own individual stream while answering the other's.
-
What does the measured Packet Loss Rate refer to, exactly?
The measured Packet Loss Rate (PLR) refers to the rate of packet exchange (request and reply). The unidirectional Packet Error Rate (PER) meanwhile is typically smaller and be calculated as PER=1-SQRT(1-PLR)
-
What data is important to take away from the Delay Profile when running Performance Analyzer measurements?
Increasing (round trip) latencies are displayed on the Delay Profile's x-axis, while the cumulative number of packets returned by a specific latency is displayed on the y-axis. The Delay Profile's curve therefore should be monotonic - i.e. packets returned within 5ms are grouped with packets returned within 10ms.
Technology
-
Which physical layer does EchoRing employ on the OSI model?
The IEEE 802.11a layer is employed for 20MHz channels.
-
Can several EchoRing networks coexist in a single location?
Yes, but each network must be configured on a different channel.
-
Do EchoRing channels overlap?
No, channel numbers are assigned along the U-NII radio band in the US and the ISM band in Europe. They do not overlap.
Updates
-
How are software updates installed?
Updates are installed remotely by R3. To ensure security, the client initiates the start of the update process.
