1.  Overview

This manual applies to the OmniSense G-900-2 family of gateways including the G-900-2-E, G-900-2-ED and G-900-2-POE model gateways.  Note that some features discussed in this manual may not apply to all models of gateways.  To identify what model gateway you have, look at the label on the bottom of the gateway in the upper right hand corner as shown in Figure   1.

 

Figure   1 - Typical Gateway ID Label

2.  Gateway Activation and Site Creation

A gateway sends all the data it collects to the OmniSense Database Server (ODS). Data can be accessed by the user at www.omnisense.com.  In order for data to be stored and accessible the gateway must first be activated and assigned to a user-created “site” at www.omnisense.com.  To create a site and activate the gateway, users must first register as a subscriber at www.omnisense.com.  Subscribers can create sites by logging into their account at www.omnisense.com and using information that describes the site to be monitored (customer name, address, email etc) after which the user assigns one or more gateways to that site.  When sensors send data through a gateway assigned to a site, those sensors are automatically assigned to that site as well. 

 

To complete site creation, the user must sign up for the OmniSense Monitoring Service, using a credit card to create a subscriber account.  The monitoring service is a fee based service.  Current monitoring rates are available at www.omnisense.com .  Monitoring is subject to OmniSense’s Monitoring Service Agreement (MSA).

Make sure to record the gateway ID which is on the ID label located on the bottom of the gateway as shown in Figure   1.  You will need this ID in order to activate your gateway at www.omnisense.com.

3.  Installation of Gateway

3.1. Site Preparation

The gateway requires a power source (either AC or Power over Ethernet if you have a G-900-2-POE) and either a LAN or MODEM (if you have a G-900-2-ED) internet connection.  When planning your site installation make sure to provide for these requirements.  The gateway should be located as centrally as possible to planned sensor locations.

3.2. Power

The gateway requires 3.3VDC which is provided by the supplied AC adapter.  Connect the adapter to an AC power source and plug the jack into the “3.3VDC” receptacle on the gateway front panel.  For G-900-2-POE model gateways power can also be provided using an 802.3af standards compliant Power over Ethernet connection.  OmniSense also sells an adapter to allow the G-900-2-POE to work with Cisco pre-standard inline power.  When power is active the PWR LED will be on.

3.3. Antenna

The antenna supplied with your gateway connects to the “Antenna” connector on the gateway front panel.  It should be screwed on “finger tight”.  The antenna is designed to swivel in all directions and must be “pointed at the sky” or in other words vertically oriented for best wireless performance.

3.4. Location and Mounting

The gateway can either be wall mounted using the built in teardrop shaped screw holes on the bottom of the case[1] or it can be placed on any horizontal surface.  Regardless of how it is mounted take care to ensure the antenna is pointed skyward. For best system wireless coverage locate the gateway central to where the sensors are to be installed.  Do not locate the gateway close to large metal obstructions such as filing cabinets or refrigerators.

4.  Front Panel LEDs

Figure   2 - Gateway Front Panel

 

The gateway front panel, shown in Figure   2, contains several LEDs which provide useful information on the status of the gateway.  The LEDs indicate the following:

1)    Wireless

a)    TX LED – consistent rapid flashing indicates normal transmitter operation.

b)    RX LED – flashes briefly while the gateway is receiving data over the wireless link.  The activity of this LED depends on the number of sensors in your system and the sensor reporting interval.

2)    Status LED – lit when gateway is communicating normally with the OmniSense Database Server or ODS. 

3)    MODEM (Only valid for G-900-2-ED models)

a)    Link LED – flashes to indicate MODEM is attempting to dial out, steady light indicates MODEM is connected to far side MODEM

b)    Act LED – when lit indicates gateway has successfully logged in to your ISP, flashes to indicate sending and receiving of packets

4)    LAN

a)    Speed LED – always off indicating 10 Mb/s link speed

b)    Link LED – Ethernet link is active, flashes to indicate transmit or receive of packets

5)    PWR – when lit indicates power is on

5.  Accessing Gateway Configuration Menu

The gateway configuration can be changed using the configuration menu.  The configuration menu can be reached by either the Ethernet port connection or the RS-232 port[2] connection.  The same menu settings are available regardless of connection method.

5.1. Using Ethernet Port to Access Configuration Menu

Use the following steps to access the configuration menu using the LAN connection.

1)    Disable and disconnect ALL network connections on your Laptop/PC EXCEPT for the LAN connection and then reboot your PC in order to force it to use an Auto Assigned IP Address.

2)    Connect the gateway to your laptop or PC using the supplied Ethernet cable.

3)    Apply power to the gateway, verify that the LAN Link LED is lit and/or flashes

a)    If the LAN Link LED does not go on and/or flash you will need to use an Ethernet crossover adapter or an Ethernet Hub.

4)    Wait for ~30 seconds while the PC assigns itself an Auto IP address. 

5)    On your PC, verify that it has assigned itself the correct Auto IP address using “Start->Run” to execute the command “cmd /K ipconfig” as shown in Figure   3. The windows IP configuration window will open, as shown in Figure   4. Note that any 169.254.xxx.xxx address is acceptable and your address need not exactly match the address shown in Figure   4.

 

 

 

Figure   3 - Running ipconfig Command

Figure   4 - Result of ipconfig Command

 

6)    On your PC, connect to the gateway configuration menu using “Start->Run” to execute the command “telnet 169.254.1.1 9999” as shown in Figure   5.  You should see a new window as shown in Figure 6.

a)    If this command fails then it is likely your PC is not using an auto assigned IP address – make sure you followed the instructions in step 1.

Figure   6 - Example of Result of Running the Telnet Command

 

7)    Press the space bar to access the configuration menu as well as view the current gateway settings.  You should see a menu as shown in Figure 7.

 

Figure   7 - Gateway Configuration Menu

 

8)    Individual settings can then be modified by selecting the desired menu item. 

a)    Don’t forget to save your changes! 

b)    Note that saving changes forces a reboot which will disconnect your telnet session from the gateway.

5.2.  Using RS-232 Port to Access Configuration Menu

Use the following steps to access the configuration menu using the RS-232 port connection.

1)    Connect the gateway’s RS-232 port to your PC’s serial COM port (usually designated “COM1” but can vary) using a serial cable[3].

2)    On your PC start a HyperTerminal window using “Start->Run” to execute the command “hypertrm” as shown in Figure   8. 

Figure   8 - Launching HyperTerminal Window

 

a)    You will be prompted to enter a name for the new connection as shown in Figure   9 – enter any name you like and click on OK.

Figure   9 - Entering HyperTerminal Connection Name

 

b)    You will then be prompted to select how to connect to the gateway – usually this is through the “COM1” port but it will vary from PC to PC and in some cases may be through a serial adapter on a USB port.  Select the appropriate COM port name and click on OK as shown in Figure 10.

Figure 10 - Selection HyperTerminal Connection

 

c)    You will then be prompted to enter the COM port settings.  Enter the settings as shown in Figure 11 and click OK.

 

Figure 11 - Setting HyperTerminal COM Properties

 

3)    You are now ready to power on the gateway.  Power on the gateway and your HyperTerminal window should look like Figure 12.  If you have problems make sure the HyperTerminal window is the currently selected window on your desktop and make sure you do not currently have any text selected in the HyperTerminal window.

 

Figure 12 - Gateway Configuration Welcome Screen

 

4)    Press the space bar within 5 seconds of power up to access the gateway configuration menu as shown in Figure 13.

5)    Individual settings can then be modified by selecting the desired menu item. 

a)    Don’t forget to save your changes!

6.  Connecting Gateway to Internet

The gateway will automatically use the LAN connection, if present.  If the LAN connection is inactive the gateway will attempt to dial out until maximum number of retries is reached.  Note that if you have an active LAN connection but you want the gateway to use the MODEM connection you must change the gateway settings from “Auto Detect Connection” to “Use MODEM Connection”. 

6.1. Connecting Gateway to an Ethernet LAN

Using the supplied Ethernet cable, connect the gateway’s “LAN” port to an available and active data port on your LAN network.  Power on the gateway and the Link LED should go on within 1-2 seconds.  If it does not, see the troubleshooting chart.

6.1.1.   Configuring the LAN Connection

The gateway is shipped from the factory to plug and play with most common LAN environments but from time to time you may need to change the settings to be compatible with “non-standard” LAN environments.  Some possible LAN configurations include:

1)    Setting a non-zero “LAN static IP”, “LAN default gateway IP” and “LAN subnet mask”

a)    You should use a static IP address only if instructed to do so by your network administrator.

2)    Setting the “LAN Static IP” to 000.000.000.000 (this is the factory default) which forces the gateway to use DHCP to acquire an IP address from your network’s DHCP server.

a)    Note that if no DHCP server is found the gateway will default to an auto-assigned IP address of 169.254.1.1 and will continue to try to get a DHCP assigned address as well.

6.1.2.   Testing the LAN connection

If the Status LED goes on the LAN connection is working.  If the status LED does not go on the LAN connection is not working – see the troubleshooting chart.

6.2. Connecting Gateway Using a MODEM (G-900-2-ED only)

You must have a working dialup account in order to use the MODEM.

6.2.1.   Connecting Gateway to a Phone Jack

Connect the gateway to an active analog[4] telephone jack using the supplied RJ-11 phone cable or a similar phone cable. 

 

Note that the MODEM interface is surge protected by a non-replaceable non-resetting slow-blow fuse.  If you use a phone line that experiences frequent surges or lightening strikes you should put a surge protector in line with the phone line to protect the MODEM from damage.

6.2.2.   Configuring Dialup Information

The gateway needs to know your Internet Service Provider (ISP) phone number, username, and password.  These must be set using the configuration menu.  If you do not already have an ISP account OmniSense recommends using www.erweb.net as they have been proven interoperable with our gateway.  In most cases one ISP account can support many gateways and in the event your ISP only allows a single login at a time the gateway will continue to attempt to login until maximum numbers of retries is reached.

6.2.3.   Other Dialup Settings

In most office environments you will need to dial 9 for an outside line in which case you should change the dialup number on the configuration menu to include a dialing prefix of “9,”.  For example:

 

·         “Set dialup number(9,18666633679)”

Do not forget the comma as that instructs the MODEM to pause before dialing the next number, and the pause is required to wait for a dial tone from the outside line.

 

You can also configure the time between server connection attempts and the maximum number of dialup retries used during a connection attempt.  By limiting the number of dialup retries you can prevent the MODEM from monopolizing the phone line in the event your ISP is not responding.

 

The gateway configuration menu also has a configuration option to allow you to specify a “MODEM Custom AT command string”.  This is rarely used and is provided for operating the MODEM outside of North America.

6.2.4.   Testing your MODEM connection

After power up and if the LAN cable is disconnected[5] the gateway will always attempt to dial up the configured ISP such that you can get immediate confirmation at the time of installation that the MODEM connection is working.  If the Status LED goes on, and you must watch it carefully as in most cases it will only stay on for a few seconds, the MODEM connection is working.  See the section on troubleshooting if you do not see the Status LED go on.

6.3. Connecting Gateway Using Proxy Servers

Some networks, especially large corporate networks, block users from direct access to the internet.  Instead, users must access the internet through a proxy server.  The gateway can operate with proxy servers – you must set the gateway’s “Remote Server IP” to the IP address of the network’s proxy server.  If you do not know the proxy server IP address contact your network administrator.

 

To set your gateway back for use in a standard (i.e. no proxy server) network environment set the “Remote Server IP” to 12.43.214.176.

7.  SD Card

The SD card is currently used only for in-the-field firmware upgrades.  In future software releases it may be used for data storage.  Currently data is stored to the internal 32 Mb FLASH file system.

The OmniSense G-900-2-E family of datalogging gateways connects the OmniSense family of sensors to the internet. A gateway communicates wirelessly with a sensor whenever a sensor initiates a wireless connection with the gateway. The gateway then stores the sensor reading in its internal FLASH. If the gateway has a internet connection the sensor reading is immediatley transferred to our database server where it is then immediately available to users on teh web site. If theer is no internet connection available, the data remains stored in teh internal FLASH memory until a internet conneciton is establihsed. It combines an x86 based embedded Linux web server and a 900MHz wireless transceiver into a compact enclosure. A Gateway constantly monitors for any Sensors attempting a connection. When a connection with a Sensor is established the Gateway will typically read out the Sensor’s log file containing the measurements the Sensor has taken, and then relay that data over an internet connection to the OmniSense FMS Database Server. The Gateway can also, on command from the FMS Web Server, update the Sensor’s time of day, read out the Sensor’s stored GPS position1, and even perform an in-service firmware upgrade of the Sensor’s operating firmware. The software in the Gateway can also be upgraded while the Gateway is in service. One Gateway can cover an area of roughly 100 meters in diameter and support more than 1000 sensors2. Multiple Gateways can be used together to provide full coverage of larger areas.

Embedded Web Server

The G-900-E Gateway uses an Intel x86-compatible processor running an embedded Linux operating system to run the processes which enable connectivity to a LAN and or the internet. The Gateway runs all the common protocols necessary for true plug and play operation with most common LAN and WAN environments. In most applications the Gateway can be plugged in and with no user configuration it will relay Sensor data to the OmniSense FMS web site.  

Wireless Link

The G-900-E Gateway uses the 915 MHz frequency band which the FCC permits unlicensed use for Industrial, Scientific and Medical (ISM) purposes under FCC Part 15.247. Within that band the G-900-E uses a technique known as Frequency Hopping Spread Spectrum (FHSS) to minimize the chance of interference with other devices sharing the same frequency band. The use of 127 different hopping channels virtually guarantees an error free link can be established between a Gateway and Sensors even in the presence of other devices, including other Gateways, sharing the same frequency band. The system uses both a Network Address (like your zip code) which is common to all Gateways and Sensors at a site and a Device Address (like your street address) which is unique to every Gateway and Sensor. The combination of addresses ensures a reliable, secure, error free link between Gateways and Sensors.


Network Security

The G-900-E is totally secure and hacker-proof by design. Hackers can not gain access to your network through a G-900-E. This is accomplished not through clever encryption or passwords but through a simple fact of the system’s architecture. A gateway only does one thing; it reads data from the sensor and relays that data to a pre-programmed IP address. A gateway accepts no commands from a sensor and it can not be configured or controlled from the wireless interface. Simply stated, accessing other devices on your LAN through a G-900-E is not possible.
