IzoT Router User's Guide 5 Welcome The IzoT Router is a ready-to-run appliance for connecting IzoT devices on an Ethernet channel with IzoT devices on an FT or RS-485 channel, and for connecting Web pages and enterprise applications to IzoT devices. The IzoT Router automatically forwards packets between the attached Ethernet LAN channel and the attached FT or RS-485 LON channel. You can add additional LON channels to the IzoT Router by plugging in up to seven external U60 DIN FT or RS-485 Network Interface Modules. You can configure the FT and RS-485 interfaces to communicate with IzoT LonTalk®/IP or classic ISO/IEC 14908-1 FT devices. The IzoT Router is available with a BACnet router that allows BACnet/IP workstations and devices on the Ethernet LAN channel to communicate with BACnet/IP devices on the FT or RS-485 LON channels. An integrated FT terminator is included with the FT version of the IzoT Router that you can enable and disable from a Web browser. This reduces the cost of installing an FT twisted pair installation by eliminating the requirement to wire a separate terminator. An integrated IzoT Server connects IzoT devices to Web clients, providing you with local Web access to monitor and control the operation of communities of devices. The IzoT Server provides an easy-to-use RESTful API with a low-overhead but powerful interface for discovering devices, monitoring their data, and controlling them via network inputs. A set of example Web pages is included with the IzoT Router. You can use these Web pages to try out the IzoT Server, to interact with your devices, and to learn the IzoT REST API. A charting page is also included that you can use to monitor and trend datapoints in your IzoT network. You can use the included IzoT Device Stack EX to build custom apps to run on the IzoT Router. This enables you to extend the capabilities of the IzoT Router to add value to your IzoT Router deployments. You can develop your custom apps using Python, C++, or C. Setting Up the IzoT Router You can set up an IzoT Router to communicate with devices, workstations, and other IzoT Routers on an Ethernet LAN channel, and you can set up an IzoT Router to communicate with FT or RS-485 devices (depending on the IzoT Router model) on an FT or RS-485 LON channels. To set up an IzoT Router, follow these steps: 1. To attach an IzoT Router FT to an FT LON channel, insert the two conductors of a LON FT network cable to into the left two screw terminals of the black LON terminal block on the right and tighten the screw terminals. In the following figure, the LON FT network cable is the bottom right cable. Do not connect anything to the right terminal of the black connector on the right (the terminal with the red X), and do not connect anything to the orange connector on the left. 6 IzoT Router User’s Guide 2. To attach an IzoT Router to an Ethernet LAN channel, insert one end of the Ethernet cable into the 10/100BASE-TX Ethernet connector next to the orange connector, and the other end into an Ethernet switch or hub connected to the same network as your computer. Connect the barrel connector of the included power supply into the Power connector for the IzoT Router. In the figure above, the Power cable is the top left cable. Connect the power supply to one of the included power cords, and plug the power cord into a power outlet. The IzoT Router is ready to use when the Power indicator turns solid blue. Finding the IP Address of your IzoT Router You can find the IP address of your IzoT Router so that you can test communication between your computer and the IzoT Router, access the IzoT Router from other IP devices, and access the IzoT Server. To test communication between your computer and the IzoT Router and to determine your IzoT router’s IP address, follow these steps: 1. Create a LonTalk/IP Network Interface for the IzoT Router Start the All Programs Echelon IzoT Network Services Utilities IzoT Network Services LonTalk-IP Interfaces application. Type a name such as LonTalk IP in LonTalk/IP interfaces, select the IP network interface from the IP Interface box (do not select a loopback interface), click Create, and close the LonTalk/IP Interfaces application. IzoT Router User's Guide 7 2. To open a Windows command prompt, click the Windows Start button, type cmd in the search box, and then press the Enter key. 3. At the command prompt, type NodeUtil –d<interfaceName>. Enclose the LonTalk/IP network interface name in quotes if there are any spaces in the name. For example: NodeUtil –d"LonTalk IP" 4. Press the Connect button on your IzoT Router to send Service and Connect messages. NodeUtil displays a message similar to the following: Received an ID message from device 1 If you don’t see any ID messages after pressing the Connect button several times, check to see if UDP port 2541 is open on your computer’s firewall. 5. Type G to go to a device, type 1 to go to device 1, and then press the Enter key. 6. Type S to report device status and statistics to display status information about the IzoT Router. The last line of the display includes the IzoT Router’s IP address. 7. Type N to preserve the router’s statistics. You can type Y instead to reset the router’s statistics counters. 8. Type E to exit the device menu. 9. Type E to exit NodeUtil. 10. Close the command prompt. 8 IzoT Router User’s Guide Using the IzoT Router LED Indicators The following tables reflect the LED color indicators for each LED on the IzoT Router’s face.

To configure the IzoT Router, open the IzoT Router Configuration page by entering the IP address for your IzoT Router in a Web browser. You will be prompted for a username and password. By default, the username is admin and the password is password. There are three types of logins for the IzoT Router: • For the IzoT Router Configuration Web pages, the default username and password is admin/password. • For the IzoT Server, the default username and password is izot/izot. • For SSH and SFTP, the default username and password is debian/debian. The following sections explain how to configure the IzoT Router using the Configuration page. Configuring LAN and LON Network Options You can configure LAN and LON options from the IzoT Router Network Configuration page. The is the default Web page that opens when you open the IzoT Router Configuration page, and you can return to the Network Configuration page by clicking Network at the top of the other IzoT Router Configuration Web pages. 10 IzoT Router User’s Guide You can configure the LAN and LON interfaces to use a dynamic or static IP address. The settings are independent. The default for the LAN interface is to use a dynamic IP address, assigned by a DHCP server for the subnet where the IzoT Router is installed. The default for the LON interface is to use a static IP address and to setup the IzoT Router as the DHCP server for the LonTalk/IP devices on the LON channel. To configure the IzoT Router to use a static IP address for the LAN or LON interfaces, follow these steps: 1. Open the IzoT Router Network Configuration Web Page. 2. For the LAN interface, change the Ethernet Interface to Static Address. 3. For the LON interface, change the LonTalk Interface to Static Address. 4. For the selected interface, change Address and Network Mask to the static IP address settings. 5. Click Submit. 6. Click System at the top of the Network Configuration Web page and then click Reboot to restart the IzoT Router. IzoT Router User's Guide 11 To configure the IzoT Router to use a dynamic IP address for the LAN or LON interfaces, follow these steps: 1. Open the IzoT Router Network Configuration Web Page. 2. For the LAN interface, change the Ethernet Interface to DHCP. 3. For the LON interface, change the LonTalk Interface to DHCP. 4. Click Submit. 5. Click System at the top of the Network Configuration Web page and then click Reboot to restart the IzoT Router. Enabling and Disabling IzoT Router Services You can enable and disable the following services provided by the IzoT Router: 12 • IzoT Server—Provides a server with a RESTful API that you can use to discover and monitor devices, and to support custom Web pages that you develop to interact with your devices. The IzoT Server is disabled by default. • RNI—Provides an LNS-compatible remote network interface (RNI). The RNI interface provides legacy support for LNS applications. Workstations and tools based on the IzoT Net Server can communicate with the IzoT Router using LonTalk/IP instead of RNI. The advantage of LonTalk/IP is that multiple LonTalk/IP devices can be attached to the LAN channel of the IzoT Router, whereas RNI can only support a single client at time. • LonTalk Routing—Provides LonTalk/IP routing between the LAN and LON channels. • BACnet Routing—Provides BACnet/IP routing between the LAN and LON channels. • FT Termination—Provides free topology termination for the LonTalk/FT channel that the IzoT Router is attached to. This option is only available on the FT model. IzoT Router User’s Guide To enable or disable an IzoT Router service, follow these steps: 1. Open the IzoT Router Network Configuration Web Page. 2. Click Features at the top of the page. 3. Select checkboxes the services to be enabled, and clear checkboxes for the services to be disabled. 4. Click Update. Managing IzoT Router System Configuration You can view IzoT Router status, change the IzoT Router username and password, reboot the IzoT Router, and reset the IzoT Router to its factory default configuration. IzoT Router User's Guide 13 To manage the IzoT Router system configuration, follow these steps: 1. Open the IzoT Router Network Configuration Web Page. 2. Click System at the top of the page.

Open the IzoT Router Network Configuration Web Page. 2. Click BACnet at the top of the page. 3. Specify the device name and device instance in Device Name and Device Instance. 4. For each LAN and LON interface, specify the BACnet port number and BACnet network number. 5. Click Submit. 6. Enable the BACnet router as described in Enabling and Disabling IzoT Router Services. Using the IzoT Server You can use the IzoT Server to discover and monitor LonTalk/IP devices, and to support custom Web pages that you develop to interact with your devices. The IzoT Server can discover devices on the LAN or LON channels using the ISI protocol. If you are using the IzoT Router with an IzoT Net Server or LNS Server, you can manually add devices to the IzoT Server. The IzoT Server works with LonTalk/IP devices on Ethernet, Wi-Fi, FT (with the IzoT Router FT), or RS-485 (with the IzoT Router RS-485) channels. The IzoT Server also works with classic LonTalk devices on an FT or RS-485 channel. To use the IzoT Server, follow these steps: 1. Open the IzoT Router Network Configuration Web Page. IzoT Router User's Guide 17 2. If the IzoT Server is not already enabled, enable it as described in Enabling and Disabling IzoT Router Services. The IzoT Server is not enabled by default. 3. Click Server at the top of the page. 4. Enter the IzoT Server username and password in Username and Password on the top right of the page, and then click Log In. The default IzoT Server username is izot and the default password is izot. 5. For documentation on how to use the IzoT Server, click IzoT SDK User Manual, and then click IzoT Server Stack. Restoring the IzoT Router Factory Defaults You can restore the factory default configuration for an IzoT Router. You can restore factory defaults for the IzoT Router not including the IzoT Server, and you can restore factory defaults for the IzoT Server. To restore factory defaults for the IzoT Router not including the IzoT Server, follow these steps: 1. Press and hold the Connect button. 2. Using a paper clip, momentarily press the Reset button (through the paper clip hole) while holding the Connect button. Alternatively, you can power cycle the IzoT Router while holding the Connect button. 3. Wait 10 seconds – until the Connect LED starts flashing red. 4. Release the Connect button. To restore factory defaults for the IzoT Server, see the IzoT SDK User Manual as described in Using the IzoT Server. 18 IzoT Router User’s Guide 2 Installing the IzoT Router in a LonTalk/IP Network This chapter describes how to install the IzoT Router in a LonTalk/IP network. IzoT Router User's Guide 19 Network Management Overview You can install the IzoT Router in a self-installed network using the ISI protocol, or you can install the IzoT Router in a network managed by an IzoT Net Server or an LNS Server. By default, the IzoT Router is configured as a repeater so that it can be used in ISI networks without any further configuration. You can enable the IzoT Server as described in Using the IzoT Server to support custom Web pages that you develop to discover, monitor, and control devices in an ISI network. To use the IzoT Router in a network managed with an IzoT Net Server, commission the IzoT Router from an IzoT Net network management tool such as the IzoT Commissioning Tool. The IzoT Net Server will configure the IzoT Router and handle LonTalk/IP network management of the IzoT Router. You can use the IzoT Net network management tool to configure the IzoT Router to be a configured or learning router, or to be a repeater. To optimize network bandwidth utilization, configure the IzoT Router to be a configured router. To use the IzoT Router in a self-installed ISI network after it has been commissioned by an IzoT Net Server, use one of the following methods: • Restore the IzoT Router factory defaults as described in Restoring the IzoT Router Factory Defaults. • Use an IzoT Net network management tool such as IzoT CT to reconfigure the IzoT Router as a repeater. To use the IzoT Router in a network managed with an LNS Server, enable the RNI as described in Enabling and Disabling IzoT Router Services, and use the RNI to interface the LNS Server to the LON channel. The LNS Server cannot be used with the LonTalk/IP channel on the LAN side of the IzoT Router—to provide compatibility with LonTalk/IP devices on an Ethernet or Wi-Fi channel, upgrade the LNS Server to an IzoT Net Server. Installing Multiple IzoT Routers in a Network You can install multiple IzoT Routers in a LonTalk/IP network. This is useful for creating large networks. You can install up to 300 devices in an ISI network, and up to 32,385 devices in a network managed with an IzoT Net Server. An Ethernet channel is typically used as the backbone channel that is attached to the LAN ports of all the IzoT Routers. The LON ports of each of the IzoT Routers may be attached to a multidrop FT or RS-485 channel. Each of the device interfaces in a LonTalk/IP network may have two types of IP addresses—host IP addresses and LonTalk/IP addresses. LonTalk/IP addresses can be represented as IPv4 addresses, such as 10.133.3.1, and as ISO/IEC 14908-1 addresses, such as domain 133, subnet/node 3/1. On an Ethernet or Wi-Fi LAN, the two addresses are assigned as follows: 20 IzoT Router User’s Guide • A host IP address is typically assigned by a DHCP server, or is assigned statically when the host is installed. • A LonTalk/IP address is assigned by the ISI engine for self-installed ISI networks, and is assigned by the IzoT Net Server for managed networks. The ISI engine sets the LonTalk/IP address to equal the host IP address if the host IP address can be mapped to an ISO/IEC 14908-1 address. The IzoT Net Server will typically assign a LonTalk/IP address that is different from the host address. ISI devices typically use broadcast messaging for all network communication. These broadcast messages are automatically forwarded by IzoT Routers in the default repeater configuration, and as a result no special configuration of the IzoT Routers is required to support an ISI network with multiple IzoT Routers. Devices in managed networks will often use unicast messaging to address datapoint updates to a single specified destination. If the destination device is on a different subnet than the source device, or if the destination address is a LonTalk/IP address that is not also a host IP address, the update will be forwarded to the configured IP network gateway for routing. In that case, you must configure the IP network gateway to forward the update to the appropriate IzoT Router. You will specify two routes per IzoT Router—one to route the LAN-side LonTalk/IP address to the LANside host IP address, and one to route the LON-side LonTalk/IP subnet to the LANside host IP address. In the latter case, the IzoT Router will handle the forwarding of LonTalk/IP packets received from the gateway to the LON subnet. The following example illustrates an IzoT Commissioning Tool network with two IzoT Routers supporting connections between devices on different LON channels. IzoT Router User's Guide 21 Figure 1. Two IzoT Routers on an IzoT CT Network The following table summarizes the host IP and LonTalk/IP addresses for the two IzoT Routers in the example network: Router RTR-1 RTR-2 LAN Host IP Address IPv4: 10.3.124.186 IPv4: 10.3.124.191 LAN-side LonTalk/IP Address LON-side LonTalk/IP Address IPv4: 10.133.1.1 IPv4: 10.133.3.1 ISO/IEC 14908-1: Domain 133 Subnet/Node 1/1 ISO/IEC 14908-1: Domain 133 Subnet/Node 3/1 IPv4: 10.133.1.2 IPv4: 10.133.9.1 ISO/IEC 14908-1: Domain 133 Subnet/Node 1/2 ISO/IEC 14908-1: Domain 133 Subnet/Node 9/1 The following table summarizes the required routes: Router IPv4 Address Subnet Mask Gateway 10.133.1.1 255.255.255.255 10.3.124.186 10.133.3.0 255.255.255.0 10.3.124.186 10.133.1.2 255.255.255.255 10.3.124.191 10.133.9.0 255.255.255.0 10.3.124.191 RTR-1 RTR-2 The first route for each IzoT Router specifies the route for messages addressed to the LonTalk/IP address of the LAN side of the router. The second route for each IzoT Router specifies the route for messages address to the LonTalk/IP subnet on the LON side of the router. The steps to define the required routes depend on the type of IP network gateway that you are using. Following is an example configuration for the gateway in an Asus Wireless Router for the example network. 22 IzoT Router User’s Guide Figure 2. Asus Network Router IP Gateway Configuration The following example illustrates a more complex network with two IzoT Routers and LonTalk/IP devices on both the LAN and LON channels, with connections between the devices. The devices on the LON channels are based on the FT 6050 Smart Transceiver, as in the previous example. One of the devices on the LAN channel is based on the CPM 4200 Wi-Fi Module, the other is based on a Raspberry Pi running the IzoT Device Stack EX. All of these devices communicate as peer-to-peer devices. IzoT Router User's Guide 23 Figure 3. IzoT CT Network with IzoT LAN and LON Devices 24 IzoT Router User’s Guide 3 Updating and Troubleshooting the IzoT Router Software This chapter describes how to update the IzoT Router and provides troubleshooting help for the IzoT Router and IzoT Server. IzoT Router User's Guide 25 Updating the IzoT Router Software You can update the IzoT Router software to the latest software release. You can update just the router software, preserving any configuration changes you have made. Alternatively, if you are using version 1.02.27 or newer, you can reflash a complete router software image to restore an IzoT Router to the factory configuration. To update the router software, you transfer the update image to your IzoT Router and use an SSH console interface to install the update. To reflash the complete router software image, you copy the complete bootable image to a USB flash drive, install the flash drive in an IzoT Router, and copy the bootable image to the eMMC flash memory on the IzoT Router. To get the links to the IzoT router software. contact Echelon Support, open a Support ticket at www.echelon.com/support, or send an e-mail request to lonsupport@echelon.com. To update the IzoT Router software, preserving any configuration changes you have made, follow these steps (substitute the version number from you IzoT Router software update for {ver}, for example, the version number will be something like 1.02.28): 1. Make a backup of any custom files that you created on the IzoT Router (e.g., Web pages, IzoT Device Apps, Server settings). 2. Download the IzoT Router software (e.g.,izot-sdk-{ver}-re.tar.gz) to your computer. 3. Use an SFTP client to copy the IzoT Router update image to the /tmp directory on your IzoT Router. 4. Use an SSH client on your computer to open an SSH console session for your IzoT Router. 5. Record the version number of the IzoT SDK on your IzoT Router. You will need this for a later step. To determine the version of the IzoT SDK on you IzoT Router, enter the following commands: cat $IZOT/izot/version.py 6. Change to the /tmp directory: cd /tmp 7. Unpack the software tar -xf izot-sdk-{ver}-re.tar.gz 8. Install the software 26 IzoT Router User’s Guide deactivate izot-sdk-{ver}-re/install 9. Once the software is installed successfully, you can remove the zipped download and unpacked files rm -rf izot-sdk-1.02.28-re rm izot-sdk-1.02.28-re.tar.gz 10. If the version number you recorded in step 5 is lower than 1.02.27, enter the following commands to enable booting from the USB flash drive: tar -xf $IZOT/etc/izot-tools-bbb.tar.gz boot sudo boot/update-boot To reflash a complete router software image to restore an IzoT Router to the factory configuration, follow these steps (substitute the version number from you IzoT Router software image for {ver}, for example, the version number will be something like 1.02.28): 1. Verify that you have version 1.02.27 or newer of the IzoT Router software. If you have an earlier version, follow the previous procedure to update to the current version. 2. Make a backup of any custom files that you created on the IzoT Router (e.g., Web pages, IzoT Device Apps, Server settings). 3. Download the new IzoT Router bootable image to your computer. 4. Create a bootable USB flash drive with the IzoT Router bootable image. To create a bootable USB flash image, use a raw image writer such as the Win32 Disk Imager utility for Windows available at sourceforge.net/projects/win32diskimager/. When you write a raw image any existing contents on the USB flash driver will be deleted so be sure to select the correct drive. 5. Plug the USB flash drive into the IzoT Router. 6. Using a paper clip, momentarily press the Reset button (through the paper clip hole). Alternatively, you can power cycle the IzoT Router. Troubleshooting Following is a summary of some problems that you may encounter with the IzoT Router, and an explanation of how to solve the problems. 1. Pressing the IzoT Router Connect button does not result in a Service message. a. If you are using OpenLDV, don’t use Unicode characters that cannot be represented as alphanumeric ASCII characters for the IzoT Network Service LonTalk/IP interfaces name. b. Make sure UDP port 2541 is open on your computer’s firewall. IzoT Router User's Guide 27 2. A device based on a Series 6000 chip, CPM 4200 Wi-Fi module, or the IzoT Device Stack EX doesn’t appear in the IzoT Router Device Browser Web page. a. Press the device Connect or Service pin button. b. Or, send a Service message from the device application. There will be a delay while the IzoT Server discovers the device and adds it to the device list. 3. Using 192.168.x.x IP addresses require special handling. IP addresses in the 192.168.x.x range are mapped to the ISO/IEC 14908-1 zero-length domain. If you are using the IzoT Net Server or IzoT Commissioning Tool, you must configure the network to use the zero-length domain to use IP addresses in the 192.169.x.x range. The IzoT Commissioning Tool does not have an interface to specify the zero-length domain, but you can change the network do use the zerolength domain using the LnsObjectBrowser tool included with the IzoT Net Server. If you are using the IzoT Server on the IzoT Router, set the domainid in the IzoT Server $IZOT/etc/lonbridge/config.xml file to use the zero-length domain with the following parameter: <domainid “0, 0 0 0”> 28 IzoT Router User’s Guide
