eKo Pro Series FAQ

260 - I'm not quite clear on is the LED information regarding the port scan mode, connection status, network status, and the sensor status. How can I interpret it?

LED pattern can be bit overwhelming at first. But once you understand the sequence, it is pretty straight forward.
When a node is reset,
- first it scans through 4 ports for sensor detection, one LED flash per port
(Green- Connection: Red- No connection)
- next it scans through the network for neighbor detection with repeated flashes
(Flashing White- pre-commissioning: Flashing Blue- Post-commissioning)
- finally, it indicates the neighbor connection status with solid LED on for about 10 sec
(Green- 2+ good neighbors: Yellow-1 good neighbor: Red- no good neighbors)

There is a useful table in the eKo manual that outlines this LED pattern. 

424 - We are designing signal conditioning for various sensors and we need to know the output impedance. Your specification sheet identifies Output Loading. It looks the same output impedance although I've never see it expressed along with capacitance in nF. Is it the same thing?

Output loading resistance (Rl) normally refers to the minimum load you should have on the sensor output to avoid creating voltage devider. The output loading capacitance (Cl) is the maximum capacitance you can have on the sensor output. If your load capacitance exceeds the recommended value, you may not get the full bandwidth of the device.

466 - How can I sort the data in the tables?

When you are in any tabular view, left-clicking the column header allows you to sort data by that field. To search for a particular set of data users can type a search string into the top left search text box. As users type the string, the table attempts to match rows which contain that search string. 

467 - How can I print the eKoView charts?

Since eKoView uses Adobe’s flash player, it is not possible to print the pages from your browsers File>Print option. The only way to print the pages is to capture the screenshot of the page (eg. using Alt + PrintScreen buttons under Windows) and then paste it into a imaging application (eg. Paint or Photoshop) and then print it from there. 

468 - What is the default factory radio channel and frequency?

The eKo base radio and nodes are factory configured to ZigBee channel 25 or 2.475 GHz. This channel doesn’t overlap with Wi-Fi band and thus minimizes the chances of interference. 

469 - What is the maximum number of nodes eKo gateway can support?

A single eKo gateway can support up to 35 eKo nodes and 140 sensing points. 

470 - How can I use the data from the sensors to increase my yield and optimize my irrigation?

Refer to the Appendix B of the eKo Pro Series manual for how to use the sensor data optimize your crop inputs. You can also refer to the <a href="http://eko.memsic.com/eko/Images/High%20Density,%20Multiple%20Depth,%20Wireless%20Soil%20Moisture.pdf"target="_blank">white paper</a> on how the data from ?Ko Pro Series system was used for greater yield, higher quality and reduced water use. 

471 - How can I create custom charts and make them available to others for viewing?

Once a chart is created, eKoView allows users to save a given chart to be reloaded later. You can save the chart using a unique name for the chart. This name can be used later by others to load and view the chart. 

472 - When I upload the latest map image of my deployment, eKoView still shows the old map image . How can I fix this?

If you had a previous map image, you will need to clear your browser cache. Follow the instructions below:

Firefox:
1) Go to Tools->Clear Private Data
2) Make sure Cache is checked and click OK
3) Close the browser, Re-open the browser and go to the ekoView page.

IE:
1) To to Tools -> Internet Options
2) Under Browsing History click Delete...
3) Delete Temporary Internet Files
4) Close the browser, Re-open the browser and go to the ekoView page. 

473 - How many nodes would I need per acre?

If the terrain is flat and the nodes can be located with good line of sight, we estimate about one eKo node per 20-25 acres.
In hilly terrains, the radio range could vary from 300 to 700 ft and we estimate about one eKo node per 2-5 acres.
For orchards, typical radio range is about 200ft and we estimate about one eKo node per acre. 

474 - What is conditioning of soil moisture probe and why is it needed?

Installing a "dry", unconditioned soil moisture probe may result in erratic/invalid readings for a number of days until the probe absorbs water/equilibrates with the soil. Typically the sensor probe needs to be submerged in water for few hours before installation and this is called conditioning. This is the reason for "conditioning" the probes before burial. 

477 - How do I find out the optimum antenna configuration?

If there are several ?Ko nodes deployed outdoors within a few hundred feet of the ?Ko base radio then placing it indoors by a window may be sufficient. However, windows, walls and other barriers can significantly degrade RF communication. Glass windows can reduce the radio range by a factor of two. Mounting the base radio antenna above the roof-line will always improve radio range. Users should consider using a remote, outdoor antenna mounted above the roof line for the best possible communication. If the roof is wood then an antenna mounted indoor, high-up by the roof line may also work. If the roof is metal then an outdoor antenna must be used. 

478 - Which radio standard do the eKo nodes use?

The eKo node integrates an IRIS family processor/radio module. IRIS provides a direct sequence spread spectrum radio (DSSS) supporting the 2.4 GHz global ISM band that is compliant with IEEE 802.15.4 standard. 

479 - During node commissioning phase, I get red LED indicator. What should I do?

The eKo node needs to be located within the radio range (within 20 ft) of the base radio during commissioning process. If you see a red LED, then the eKo node did not communicate to the base radio. Check that the eKo base radio’s “Power OK” LED is on along with Disk 2 LED of the eKo gateway. In current release firmware, nodes do NOT indicate a failed commission. The WHITE commissioning LED flashes until the node is commissioned or it gives up (approx 15 minutes) at which time it shuts itself off 

480 - What are some good deployment practices?

Below are some good deployment practices to consider
• Determine the optimal antenna and mounting configuration for your base radio and gateway.
• If the eKo base radio is located remotely from the nearest eKo node, consider using a repeater node.
• For high reliability consider a UPS (battery backup) to keep the gateway powered during power outages
• If possible, place the eKo nodes at least 5-12 feet above the ground. Radio range will be reduced as the units are placed lower to the ground.
• A clear line-of-sight between units is preferable. Trees, foliage, and canopies that are higher than the antennas will reduce radio range.
• Establish network by placing the first eKo nodes close to the base radio and then working outwards, trying to maintain the green LED indicators..
• After deploying the network, monitor the network for a few hours before burying soil sensors in case the node needs to be moved or another node used as a relay. 

481 - Can the raw data from the server be accessed for near real time control of other equipment?

The raw data is available over XML stream. 

483 - How can I upgrade the eKoView software?

Crossbow may periodically provide an upgrade file to enable new functionality, fix bugs, etc. You can download this file from <a href="http://eko.memsic.com/eko/Downloads.aspx"target="_blank">eKo downloads</a> page to your PC. Each update will have a security code associated with it to verify its integrity. You can use Gateway Administration page to upgrade eKoView. Refer to the Appendix A of the eKo Pro Series manual for detailed procedure. 

484 - Can I use web browser buttons to navigate between eKoView pages?

You may use Forward and Back buttons in your web browser to navigate between eKoView pages.
However, since eKoView uses Adobe’s flash player, do not use Refresh/Reload buttons in your web browser to refresh the page (use Refresh link on the top right hand side instead). Should you accidentally use these buttons, then you will need to login back into eKoView. 

485 - What is the data reporting interval of the eKo Nodes? How can I change it?

The eKo nodes are factory configured to send sensor data once every 15 minute. In the current release, it is fixed and can not be changed by the user. 

486 - How can I set-up remote access for eKoView?

To set-up remote internet access for eKoView through a firewall, you need to do the following:
1. Determine the IP address of the router and the eKo gateway.
2. Log into your router’s web page
3. Enable and open the following ports on the router for the eKo Gateway
Port 9003 for XCommands
Port 9005 for xml stream
Port 9080 for HTTP
Port 9843 for Flash player security
4. Save these settings and reboot the router
5. The remote internet access to eKoView will be available through the following URL
http://{Router IP address}:9080
Refer to the Appendix A of the eKo Pro Series manual for detailed procedure. You may also refer to this <a href="http://www.portforward.com/english/routers/port_forwarding/routerindex.htm"_blank">page</a> for step-by-step procedure on how to set-up port forwarding on an extensive list of routers. 

493 - Which mesh routing protocol do the eKo nodes use?

The eKo nodes come pre-programmed and configured with Crossbow’s XMesh low power networking protocol. This provides plug-and-play network scalability for wireless sensor network.

494 - Where can I download and install eKoView software from?

eKoView software comes bundled and pre-installed on your eKo gateway. No download or installation is required. You can access eKoView from a simple web-browser on a PC connected to the internet. The latest updates to this eKoView is available from the <a href="http://eko.memsic.com/eko/Downloads.aspx"target="_blank">downloads</a> page. 

495 - How can I clear alerts that show in eKoView page?

Alerts page under Sensor tab displays most recent alerts from all nodes in the form of tabular data. The Alerts can be cleared from the Alerts page using the buttons provided on the lower left side of the screen. If you want to disable the alert notification altogether, you need to delete the alert from Configure Alerts page under Configure tab (requires Admin privileges). 

496 - How can I find out the version of eKoView I have on my gateway?

The eKoView version will be displayed at the tooltip when you move and hold your mouse cursor on eKoView logo at the upper right side of the page. You can also get this info from Server Health page under Network tab. 

497 - What are the options available to export data from eKo system?


Following are the 4 available methods of exporting sensor data from eKo system:
1. Sensor data displayed in an eKoView chart can be directly exported to csv (comma separate value) files compatible with Excel.

2. Sensor data (converted and/or raw readings) can be logged to the eKo gateway’s flash memory card (csv files) as data is received by the gateway.

3. Specific sensor data within defined date ranges can be exported from the gateway’s database.

4. A real time XML data stream can be enabled for remote server storage.

Download the application note from the attachment for details about each of these options. 

498 - I can not seem to open eKoView welcome page. What can I do now?

1. Type http://hostname in your web browser. Users can use the hostname of their eKo gateway (eg. eko-xxxxx, where xxxxx is the serial number) written on a sticker attached to the bottom side of the device.

2. If that doesn't work, you will need to use the IP address of the eKo gateway device. The IP address of the eKo gateway can be found either using the GatewayConfig tool. Refer to the Appendix A of the eKo Pro Series manual for detailed procedure. Once IP address is found, type http://IPAddress in your web browser.

3. If the above step don't work either, login to your router's webpage and look for eko-xxxxx under attached devices. Consult your router’s user manual for details.

4. A final way to find the IP address of an eKo gateway is to listen to its beeping sequence at the end of the boot-up period. Refer to the Appendix A of the eKo Pro Series manual for detailed procedure. 

499 - The hostname doesn't bring up ?KoView welcome page. What can I do now?

For users on a corporate or university network, the hostname should be enough to allow users to find the application through the browser. Most home routers do not support the means to use the hostname. In those cases users will need to use the IP address of the ?Ko gateway device. The IP address of the ?Ko gateway can be found either using the GatewayConfig tool. A final way to find the IP address of an ?Ko gateway is to listen to its beeping sequence at the end of the boot-up period. Refer to the Appendix A of the ?Ko Pro Series manual for detailed procedure. 

500 - How long will the batteries last without the sunlight?

The eKo Nodes can run up to 3 months without any sunlight. 

503 - How do I set-up gateway for static IP address?

The eKo gateway is factory configured for DHCP (dynamic IP address). Alternatively, it defaults to the static IP address 192.168.1.77 if a DHCP address can not be obtained (after 60 sec). If a different static IP address is desired it will need to be reconfigured using Gateway Administration page. Refer to the Appendix A of the eKo Pro Series manual for detailed procedure.

For static IP configuration only: If the eKo gateway is to be accessed via a remote network, e.g., via an internet router, the gateway field has to be set with the address of that router (typically, 192.168.1.1 for this example). If the field is left blank, remote access to the gateway as well as other remote functions such as time synchronization will not function. 

504 - Where can I find the hostname for my eKo gateway?

You can find the default hostname of the eKo gateway on a sticker attached to the bottom side of the device (eg. hostname is eko-xxxxx, where xxxxx is the serial number). If you changed the hostname using Gateway Administration and can’t remember it anymore, you may run GatewayConfig tool to find out the hostname

505 - I don't have Ethernet connection at my vineyard. Can I use Wifi or Cellular connection to connect to eKo gateway?

The current support for the eKo gateway is limited to Ethernet network. We have plans to extend this to Wifi and cellular networks. 

506 - I can't seem to access the files on my gateway using samba. What is wrong?

For security reasons File Sharing is disabled by default. Refer to section Appendix A of the eKo Pro Series manual on how to enable it via the Gateway Administration page. It is highly recommended to place the eKo gateway behind an Internet firewall. Never enable File Sharing if the gateway is directly connected to the Internet. 

507 - How can I secure the data on my gateway server?

Few measures you can take to secure the data:
1. Change the default passwords for your eKo Gateway from the Gateway Administration page.
2. Disable file sharing via the Gateway Administration page.
3. Place the eKo Gateway behind your firewall and don't open the SSH port (i.e. 9022). 

508 - What sensors are supported by eKo Pro series system?

The following sensors are currently supported by eKo Pro series system.
• eS1100 soil moisture potential sensors
• eS1110 soil water content sensors
• eS1201 ambient temperature and humidity sensors
• eS1301 leaf wetness sensors
• eS1401 solar radiation sensors
• eS2000 weather station sensor suite

We will expand this sensor offering to more sensor types and makes in the future.

509 - How do I attach my own custom sensors to eKo nodes?

eKo nodes are designed to accommodate almost any type of low power sensor and allow for future support of many sensors. Two different types of sensor interfaces are supported: Simple for standard 2 and 3 wire sensors and Smart which uses Crossbow’s ESB (Environmental Sensor Bus) for intelligent sensors. As new sensors are introduced users will be able to simply connect them to the nodes using the eKo’s auto-identification scheme. 

510 - How long can the nodes operate before I need to replace the batteries?

eKo nodes are solar-powered with rechargeable batteries to ensure that the sensors stay up and running for years on out. Nodes can run up to 3 months without sunlight. With reasonable solar hours, the batteries can last at least for 5 years. 

512 - What is the maximum number of users that can simultaneously connect to eKoView?

We recommend limiting the maximum number of simultaneous connections to under 10 users.

513 - How can I export all the data into Excel file?

From the chart tab, users can export the displayed data to a CSV file. When viewing a chart, you can export the chart data by clicking on the “Export Data” link at the top left side of the page. This CSV file can be later opened using MS Excel application. 

514 - I recently purchased an EN2120 long range nodes to use with my existing system. I was able to successfully commission the node, but I don't see any internal sensor data from this node. I am using eKoView 2.4.30 on the gateway. How do I fix this?

The EN2120 long range node requires a special ConfigXML file that is available on gateways running eKoView 2.4.31 or later. If you are using 2.4.30 or earlier versions of the software, you will need to download the attached XML file, unzip it and then copy it over to eKo gateway’s /xbow/xserve/configxml folder. You can copy the file using Samba utility as described in section 7.2.2 of the user’s manual.
Once the file has been copied, reboot the gateway and you should see internal sensor data from EN2120 in eKoView. 

516 - What is the data reporting rate from eKo sensors? Can this be changed?

When you turn the eKo node on, for the first hour that data is reported every 31.25 seconds. After the first hour, the data reporting interval changes to every 15 min and 37.5 seconds.

In the current release, the user can not change the data update rate. 

519 - I have a Davis wireless weather station. Will eKo system interfere with it?

No, eKo will not interfere. The eKo radio channel is at a different frequency. We have run eKo at Camalie vineyards for two years along with a Davis weatherstation and have never experienced any interference.. 

520 - I attached a new sensor to the node, but I don't see the sensor or its data in eKoView. How can I make eKoView identify the new sensor?

Any time a new sensor is attached the ON button must be pushed in order for the node to recognize the sensor. Make sure that you have pressed the ON button and gone through the sensor commissioning process. 

521 - Where can I find the node ID or serial number of my eKo node?

The serial number of your eKo node can be found on the label attached to the backside of the node. 

522 - What are the system requirements to run eKoView?

The following are the minimum system requirements to run eKoView
• PC connected to the Internet.
• Web browser, e.g. Microsoft’s Internet Explorer or Mozilla’s Firefox
• Adobe’s Flash Player 9.x. 

523 - What is the resolution of the ADC used on eKo nodes/sensors?

The ADC of the eN2100 itself offer 10-bit resolution. 

524 - Can the timing of data from each node be synchronized with the rest of the network?

The nodes in the network are not time synchronized. The eKo pro series products are currently targeted for applications that don't require critical timing or real-time control. 

527 - How do I change the time zone for my gateway?

The eKo Gateway ships pre-configured from the factory with US Pacific time zone. Since the data is time-stamped relative to the time zone, users may want to change this to their time zone. The eKo Gateway Administration allows user to change this default time zone. Refer to the Appendix A of the eKo Pro Series manual for detailed procedure. 

528 - Do you have any specifications or manuals that explain how the gateway is configured or can be configured to ensure no potential security problems by plugging the gateway into the network.?

Do you have any specifications or manuals that explain how the gateway is configured or can be configured to ensure no potential security problems by plugging the gateway into the network.? 

531 - Where can I find the SMTP mail settings for my mail server?

The Alert Mail Settings dialog window provides SMTP presets for commonly used mail services such as Gmail, Yahoo Mail and Hotmail. If you are using one of the other mail service provides (eg. Comcast, SBC, AT&T etc), you should consult the service provider for these SMTP settings. You need to find out SMPT host name, Port number and settings to specify in ?KoView.

NOTE: SMTP settings – Yahoo and Hotmail only support paid accounts. To send alert mail from a free E-mail service, register a new Gmail account with Google. 

533 - Which sensor elements are used in eKo sensors? Where can I find the specifications?

eS1101 uses Watermark 200 soil moisture sensor. For detailed specifications <a href="http://www.irrometer.com/agcat.htm#WM"target="_blank">click here<a>.
eS1101 also uses Davis 7817 soil temperature sensor. For detailed specifications <a href="http://www.davisnet.com/product_documents/weather/spec_sheets/7817_spec_Rev_E.pdf"_blank">click here<a>.

eS1201 uses Sensirion SHT-75 ambient temperature and relative humidity sensor. For detailed specifications <a href="hhttp://www.sensirion.com/en/01_humidity_sensors/06_humidity_sensor_sht75.htm"_blank">click here<a>.

535 - During deployment phase, I get Red LED indicator. What should I do?

If you see a red LED indicator, move the node location within the RF range of at least one other eKo node until you see a yellow or green (preferable) LED indicator. Consider:
• If possible, place the eKo nodes at least 5-12 feet above the ground. Radio range will be reduced as the units are placed lower to the ground.
• A clear line-of-sight between units is preferable. Trees, foliage, and canopies that are higher than the antennas will reduce radio range. 

538 - What distance or range can I get between 2 neighboring nodes?

Typical distance ranges from 600 to 1500 feet depending on placement, obstacles, and radio interference.

540 - What is the difference between eS1100 and eS1110 sensors? Which one is better for soil moisture measurement?

The eS1100 is a Watermark water potential sensor and measures how much pressure the roots apply to extract water. The eS1110 is a Decagon EC-5 water content sensor that measure the percent of water present in the soil. If you're doing stress irrigation and want to correlate to leaf potential (pressure bomb measurements) then we suggest the eS1100. The eS1100's should be located in the root zone. If you're not using drip irrigation the roots may be growing in all directions so this may not help a lot. If you are only interested in amount of water present in the soil then use the eS1110. 

542 - I don't get any data from my eS1201 temperature/humidity sensor when I use it with new leaf wetness sensor I purchased. Are they not compatible?

There was a problem when using "early" eS1201 hum/temp sensors (-01 and -02 revision) with new 3 wire devices (leaf wetness, solar radiation and soil moisture content). The current version -03 has the fix.

Work-around:
If you have an early version (check the label attached to the sensor), the Hum/Temp sensor MUST be put at a Port number lower/less than the Port number of the the 3 wire sensor (eg. attach the eS1201 sensor always on Port 1). 

543 - I can see eKoView welcome page, but can not log in and it gives me a login error. What can I do now

New security policies in the latest Flash Player release (v9,0,124,0) have caused issues logging into eKoView (v2.4.24) .

To determine if this issue is applicable to your server make sure the following are true:

1) After typing username and password, the “Loading” spinner spins for ~ 1 minute and then returns with the message “Login Error: Connection to server could not be established”.

2) Place the mouse over the “eKoView” image on the top left corner. A popup should indicate the version of eKoView as “Web Version 2.4.24”

3) Right click the mouse anywhere on the eKoView web page and select “About Adobe Flash Player 9…”. A popup window should indicate that you are using “Adobe Flash Player 9 ( 9,0,124,0)”.

All of the statements above must be true for this issue to apply.

Work-around:
Upgrade to eKoView v2.4.25 from <a href="http://www.xbow.com/Eko/Downloads.aspx" target="_blank">downloads</a> page.

You can use Gateway Administration page to upgrade ?KoView to this new version. Refer to the Appendix A of the ?Ko Pro Series manual for detailed procedure.

NOTE: When re-visiting a site which has been upgraded for the first time, please verify that your browser has reloaded the correct version of eKoView. To verify your version put your mouse over the "eKoView" image on the top left corner. The correct version is 2.4.25. If you have a pervious version, you will need to clear your browser cache. Follow the instructions below:

Firefox:
1) Go to Tools->Clear Private Data
2) Make sure Cache is checked and click OK
3) Close the browser, Re-open the browser and go to the ekoView page.

IE:
1) To to Tools -> Internet Options
2) Under Browsing History click Delete...
3) Delete Temporary Internet Files
4) Close the browser, Re-open the browser and go to the ekoView page. 

546 - How can I use network tab as a network diagnostic tool?

The Network tab displays network diagnostic information, used to determine network health.
If the packet yield of a node is poor or intermittent check the Mesh Health page. This view will show the RF connectivity of a unit to its neighbors. The neighbor table displays all neighbors that the unit can communicate with and the Link Quality is a measure of how good the node can receive messages from the neighbor and how well the neighbor can receive messages from the node (bi-directional quality). A link quality of 1.0 indicates that 100% of messages are received.
Link Quality 0.95 0.50 means that the node receives 95% of the messages from the neighbor and the neighbor receives 50% of the nodes messages.
Crossbow’s mesh networking software using automatic message retries if a neighbor unit does not receive a message. After trying multiple times it will switch to another neighbor. Even if only 50% of the messages are received by a neighbor this retry capability may still deliver 100% of all messages forwarded. 

602 - The '"Disk 1" LED of my gateway doesn't come on. What is wrong?

Check and make sure that the side with the electrical contacts on the USB disk mates with the contacts inside the USB connector. If the USB disk is plugged in the wrong way the eKo gateway will not boot.
