  • The WiFi Device may be out of range of the access point or router – move the Device closer
  • The wireless network name (SSID) for your network may be hidden – select Other Network and enter the parameters manually
  • Restart your access point or router
  • For Loggers sold before July 2016 – Your wireless network may not support the required 802.11b data rates – check configuration of your access point or router.  Refer to Comark RF300 PIB Help with Network Requirements and Settings.
  • On rare occasions the SSID may contain invalid characters which can stop it from being displayed.  Refer to the knowledge base article Help with Network Requirements and Settings.

If you have tried all of the above but the wireless network still does not appear in the list, please contact your IT Administrator or supplier

 


My wireless network appears in the list but the WiFi Device fails to connect

  • Have you selected the correct wireless network?  There may be multiple networks with the same name (SSID).  If necessary check the MAC Address of your access point or router against that shown in the list of networks.

GT04

  • Check that password being entered is correct – don’t forget it is case sensitive
  • The WiFi Device may be out of range of the access point or router – move the Device closer
  • If the wireless network uses WEP Encryption, ensure that the HEX key is being entered rather than the password. Online converters are available.  The passkey consists of a string of characters A-F and numbers 0-9.
  • Does your password contain any punctuation or special characters? Most punctuation is fine but some characters, particularly spaces and commas cannot be handled by the WiFi Sensors.  Try changing the password to remove any special characters.

If the above has not resolved the problem please try the advanced options below

  • If the PC has two network connections you may need to manually select the network which will be used to communicate with the WiFi Devices.  Refer to the knowledge base article Help with Network Requirements and Settings for further information.

Help with Network Requirements and Settings

Help with Network Requirements and Settings

This knowledge base article offers guidance on Network Requirements and Settings for the RF300 Diligence WiFi sensor products.


What Network Requirements are there to use the RF300 Diligence WiFi Sensor Products?

The RF300 Diligence data logging sensors require an 802.11b compatible network and support the following encryption methods:

  • No authentication or encryption – not recommended
  • WPA/WPA2 Pre-shared key (PSK) — recommended
  • WPA/WPA2 Enterprise – see below for more information
  • WEP – 64bit or 128bit encryption. Requires WEP passkey in hexadecimal rather than ASCII passphrase.

For Loggers sold before July 2016 The WiFi Sensors will only operate on an 802.11b network using data rates of 1,2,5.5,11 Mb/s. Wireless access points must be configured to allow 802.11b traffic (not g or n only modes).

For Loggers sold from July 2016 onwards Comark has upgraded the Diligence WiFi Data Logger range from ‘b’ (IEEE 802.11b) to ‘bgn’ (IEEE 802.11b/g/n) WiFi compatibility.


How do I tell them apart from the old versions?

Telling them apart is straightforward. The part number for the logger can be found on the rear of the logger

along with the MAC Address which, for all ‘bgn’ enabled products is 98:8B:AD:20:00:00 -> 98:8B:AD:2F:FF:FF


By default the WiFi Sensors will obtain an IP address via DHCP, this is normal for most networks.  The IP address can also be manually configured – see below for more information.

When using the PC software the sensors must be connected either wired or wirelessly to the same network and use the same IP address range as the PC.

If the software is running on a virtual machine it may be given a different IP address to the host PC. It will need to be given an IP address that is in the same range as the WiFi Sensors.

If you have multiple network connections on the PC, the software may not be able to automatically choose the one which the WiFi Sensors are connected to – see below for more information.

When using the Comark Cloud service the sensors and the PC do not need to be on the same network but both require an internet connection during setup.

Wireless access points must have wireless isolation or guest modes disabled to enable communication between devices.

Corporate networks may need additional configuration to allow communication between the sensor and the PC.

MAC Address filtering on the access point must be disabled or the address of the sensors included in the allowed list.  The MAC Address can be found on the serial number label on the back of the unit.


How do the RF300 Diligence WiFi Sensor Products communicate on the network and what firewall settings may be required?

The WiFi Sensors communicate using different methods depending on whether they are connected to a local PC or to the Comark Cloud.

All communication is initiated by the WiFi Sensors themselves.  While not communicating, the devices are in a low power mode with the radio module turned off.


Local PC

The Firewall must allow full access to the WiFi Sensor Software, failure to do so will prevent the sensors from communicating.

From Application Firmware version 3.xx onwards, the WiFi sensors primarily use TCP port 10080 to communicate with the PC Software.  In addition they use UDP broadcast packets on UDP ports 1024 and 8010 for alarm notifications and discovery of a PC once TCP connection has been lost.  Any firewalls running on the PC will need the TCP and UDP ports open for correct operation.

In order to set up the WiFi Sensors on the Cloud, both the PC Software and the Sensors require an internet connection.  The PC Software connects to the Cloud via a HTTPS connection in order to set up the sensor.  This is only required during initial configuration.  The WiFi Sensors communicate with the Cloud using TCP port 14354.  Most domestic routers do not have restrictions on outbound TCP connections but corporate networks may require an exception in the router/firewall.


UDP Broadcast

Communication between the WiFi Sensors and the RF324 WiFi Alarm unit is achieved using UDP broadcast as the sensors do not have knowledge of how many RF324’s are listening on the network.  It is also used by the WiFi Sensors when running in local PC mode when TCP connection to the PC is lost.  This is in order to recover from the situation where the IP address of the sensor may have changed.  In order to reduce network traffic, many managed wireless networks have UDP broadcast traffic filtered by default which may inhibit the operation of the WiFi Devices.  On Aruba managed networks this setting is called ‘Drop Broadcast and Multicast Traffic’.


My PC has multiple network connections, is this a problem?

When using the WiFi Sensors with the PC software, they must be on the same network in order to communicate.  If the PC has multiple network connections e.g. wired and wireless, the WiFi Sensor Software may not be able to automatically select the correct network connection.

GT03

On the Wireless Network selection screen, click on the green antenna symbol on the top left of the window.  This will cause a drop-down box to appear on the bottom left.  Select the network adapter which corresponds to the same network as the WiFi Sensors.  Then continue the setup as normal.


How do I configure my WiFi Sensors with a static IP Address?

If you do not have a DHCP server on your network or wish to manually assign an IP address, these settings are found on the Advanced Network Options screen.

Net_01

Ticking the box on the Wireless Network Selection screen then clicking ‘Next’ will take you to the advanced options.

Net_02


Can I connect my WiFi Sensors to a wireless network with Enterprise Authentication?

Enterprise Authentication is supported on devices with System Firmware of 2.3.12 and above.

We support the following Authentication Methods:

  • PEAP/MSCHAPv2
  • FAST
  • TTLS

Selecting an Enterprise network will prompt entry of a username and password:

Net_03

You also need to select the authentication type in the dropdown box.  Consult your IT Administrator if you are unsure what type of enterprise network you have.

We do not support the following types which require a client certificate to be installed:

  • TLS
  • GTC
  • LEAP

 


My Wireless Network doesn’t appear in the list, what could be causing this?

If you have refreshed the network list several times but your network does not appear, there are several possible causes:

The wireless network could be out of range of the sensor, try moving the sensor and the access point/router closer together and trying again.

The wireless network name (SSID) could be hidden.  Either change the access point or router configuration to make the SSID visible or use the option to connect to Join Other Network and enter the details manually.

Net_04

The SSID may contain invalid characters.  The wifi sensors are unable to handle certain special characters such as spaces or commas in the SSID or trailing spaces at the end.  You may need to change the SSID of the network.  This also applies to passwords.

The wireless network may not have the correct modulation or data rates enabled.  The WiFi sensors require 802.11b to be enabled.


I am getting an ‘Error Saving’ message at the end of the set-up process for my WiFi Sensor, what could be causing this?

At the end of the set-up process, the WiFi Sensors transmit a test message to the PC Software or to the Cloud in order to confirm that the configuration is correct.  This error message most often due to the test connection failing.

 


Local PC

The most common reason for the test connection to fail is the packets being blocked by a firewall on your PC.  Please follow our firewall configuration guides to ensure that you have the required ports open.

In order to communicate, the PC must be on the same network as the wireless device which the sensors are connected to.  Another cause of the test connection failing can be if you have multiple network adapters on your PC, such as a wired and wireless connection or a USB 3G Modem connected.  Please see the help section on multiple network adapters.

 


Cloud Service

When connecting a sensor to the Cloud, the message is transmitted across the internet to the Cloud Server.  This requires the sensor to be able to access the internet via the wireless network on TCP Port 14354.  Most domestic internet routers do not have restrictions on outbound TCP connections by default.  Users on corporate networks may need to contact their IT Administrator to ensure that TCP Port 14354 is open for outbound traffic.

 


I have multiple access points with the same name (SSID), could this cause problems with the WiFi Sensors?

Devices with System Firmware of 2.3.12 or above are capable of selecting the strongest access point with the SSID it is configured to use.  If you are moving a sensor between the coverage of two access points, it may lose connection temporarily with the PC software or the Cloud while it finds the new access point.

Devices with previous versions of the System Firmware will chose the Access Point with the lowest channel number.  If you have multiple Access Points with the same SSID and are experiencing issues with a device showing a low signal strength despite being close to an access point it may be trying to connect to one further away.  In order to work around this issue it is possible to lock a WiFi Sensor to the MAC Address of an Access Point.  This option is found on the Advance Network Configuration screen.

Net_01

Ticking the box on the Wireless Network Selection screen then clicking ‘Next’ will take you to the advanced options.

Net_05

Enter the MAC Address of the access point you want to lock the sensor to.


There is an Enterprise Level Firewall (eg Sonicwall, Fortigate) on our network, will this stop the WiFi Sensors working on the Cloud?

The answer to this depends very much on the configuration of the Firewall.  If the Firewall is configured to allow unrestricted outbound traffic, it should not cause any issues.

Some corporate firewalls are configured to only allow traffic from known or authenticated clients, eg using Windows Domain Login.  As the WiFi Sensors are unable to respond to requests to identify themselves, the Firewall may not allow access through to the internet.  In this case, an exception will need to be added for the IP or MAC Address of the WiFi Sensor. Please consult your IT Administrator.

Battery Life Expectation

Battery Life Expectation

This article offers guidance on battery life for the RF300 Diligence WiFi sensor products


How long will a fully charged battery last in my RF300 Diligence WiFi sensor?

The RF300 Diligence WiFi data logging sensors are powered by quality LiPo batteries. The battery life of the sensor is dependent on use.  Transmitting data uses a lot of battery power. By increasing the time between transmissions the battery will last longer. See the table below.

Battery_Life_Table

The product will arrive partly charged but you should charge it for 24 hours before use for optimum performance. The battery can be recharged using a PC, a USB wall adapter, or a portable USB battery pack using the USB lead provided. It can also be permanently powered by a USB wall adapter or USB battery pack. Readings may be affected for some sensor types, while the internal battery is being charged. However once charged, continued connection of the charger will have no effect.

Battery life is dependent on a wide range of parameters including:

  • Transmission period.
  • Operating temperature. (Lower extremes will have a significant effect).
  • WiFi encryption method.
  • WiFi encryption key rotation frequency (determined by the AP/router).
  • Signal strength between router and WiFi device.
  • Presence volume and type of WiFi traffic from other devices.
  • Sample rate.

Regardless of whether you have chosen to store your data on the PC or on the Comark Cloud, optimum battery life is achieved when each data transmission from the WiFi sensor is successfully received by the host. If the PC Software is not running, the WiFi network is down, or for any other reason connection between sensor and host is lost, the sensor attempts to periodically re-establish communications until connection is made and data is synced. To ensure optimal battery life we recommend that wherever possible, a wireless connection to the host is permanently maintained.

Battery_Life_Diagram_01


What is the service life of the battery inside my RF300 Diligence WiFi Sensor?

It is generally accepted, that the service life of a battery has come to an end when it reaches 80% of its original capacity (of course the battery will continue to work satisfactorily beyond this). Our products use a quality LiPo (Lithium Polymer) battery which, under normal conditions of operation, charging and storage, will provide a service life in excess of 300 charge/discharge cycles.

For example, if you recharge your sensor every three months, the battery service life would be at least 75 years.


How should I store my RF300 Diligence WiFi Sensors?

If you need to store your WiFi sensors for any length of time, we recommend the following guidelines in order to preserve battery capacity..

  1. Do not exceed the acceptable storage temperature range of -20 to +30°C. Storage at room temperature is OK, although more battery capacity is preserved at lower temperatures.
  2. If the WiFi symbol is shown, flashing or fixed, in the top left corner of the LCD then the WiFi sensor must be factory reset by pressing and holding the button for 20 seconds, prior to storage.
  3. The battery should be part-charged to 40-50% capacity prior to storage. This can be achieved by charging the WiFi sensor for approximately 4 hours from flat. We do not recommend storing a fully charged or fully discharged WiFi sensor.
  4. For long-term storage, we recommend that batteries are periodically topped-up to maintain a nominal 40-50% capacity. We recommend recharging for 3 hours every 6 months.

Why is the battery in my RF300 Diligence WiFi Sensor not charging?

It is safe to recharge the WiFi sensor between 0 and 40°C. A safety feature inside, prevents charging when the internal temperature is outside this range. This ‘charging error’ condition is indicated when both MIN and MAX are shown together on the LCD.

Battery_Life_Diagram_02b


How do I ensure that I get the best possible battery life from my RF300 Diligence WiFi Sensors?

  • Do not exceed the acceptable operating temperature range of -20 to +60°C. Lower temperatures will significantly reduce battery capacity.
  • Choose the longest Transmission Rate suitable for your application. Remember, you will receive alarm notifications immediately, regardless of your Transmission Rate setting.
  • Wherever possible avoid deep discharging your sensor. Recharge your sensors while they still have some charge left on a schedule to suit you.
  • If storing your sensors, do not exceed the acceptable storage temperature range of -20 to +30°C and maintain a 40-50% charge.
  • Wherever possible maintain a permanent wireless connection to the host (PC or Comark Cloud).
