      Meeting Room Display Tablet FAQ
      General Sensor FAQ:

      Question

      Answer

      Why is the System LED rapidly blinking on my sensor?

      While a sensor is not joined to a network it will continuously blink the System LED to indicate its unconnected status to the user. Ensure your LoRaWAN gateway is connected to your Network Server and verify the DevEUI, AppEUI and AppKey for the device.

      Why does my LoRa LED blink periodically?

      The LoRa LED indicates LoRa traffic being sent or received by the device. A short blink indicates the sensor has just transmitted, while a longer blink indicates the sensor has received a message.

      How do I add my sensor to a Network Server?

      Provisioning a sensor on a Network Server will vary based on your Network Server provider. An example of how to perform this on the TEKTELIC Network Server is available in your sensors user manual. Most network server providers will require you to enter the DevEUI, AppEUI and AppKey of your device on their service.

      What version of LoRaWAN do the sensors implement?

      All TEKTELIC Sensor products run LoRaWAN 1.0.2

      The serial numbers on my case are different from the serial numbers on the circuit board. Did my order get mixed up?

      All TEKTELIC products have multiple serial numbers so we can track the devices at each stage of production. It is normal that you sensor board and sensor assembly have different numbers.

      What can I find the commissioning values for my sensors? (DEVEUI, APPEUI and APPKEY)

      We keep the commissioning values for each sensor secure on our own server. We send the commissioning values for each sensor sent with a shipment but if this was misplaced please send the serial number the revision and the Tcode of the sensor and we can get the information for you.

      Why is my sensor sending more packets than the Network Server receives?

      This occurs when the channel plan does not reflect the number of channels accepted by the gateway. By default, all sensors come up in 64 channel mode which results in lost packets if a gateway with less than 64 channels is used. If you have an 8 channel gateway for example, ensure this is configured in the device settings in the Network Server. In the TEKTELIC NS under the "advanced network settings" tab change the configuration of the "default channel mask" to reflect the number of channels used by the gateway used.
       
      Meeting Room Display Tablet FAQ:

      Question

      Answer

      What are the possible power options for the externally powered tablets?
      • Power input, DC Port: 5 VDC +/-10%
      • Power Input, POE: IEEE 802.3af class 1, Mode A or Mode B or 4-pair Mode 48 VDC nominal, 37 to 58 VDC operating range
      What kind of walls can I mount the tablet on? 

      The tablet can be mounted on any type of wall using the wall plate provided in the product package.

      • For dry walls, use the provided screws to tighten the plate on the wall before mounting the tablet.
      • For glass walls, use double-sided adhesive tapes that are strong enough to hold the tablet in place. The slots provided on mount plate allows for adjustment to level the mount plate.

      What is the radio transceiver on the tablet?

      The tablet features the Semtech SX1262 as the radio transceiver. This device can communicate via FSK or LoRa signals with a frequency coverage of 150 MHz to 960 MHz The LoRa radio specifications include:

      • 22 dBm maximum Tx power
      • -137dBm Rx sensitivity (SF12 on a 125-kHz channel)
      • Programmable bit rates up to 300 kbps
      • LoRa and FSK modulation

      What is the display technology on the tablet?

      E-ink display technology used on the Memo is a reflective, bistable, and paper-like display with a 758 x 1024 resolution and 16 gray levels.

      The display does not need backlight to hold screen images, rather it uses the ambient light of the environment to reflect the surface of the display making it seem like it's always ON.

      When the tablet is not active, the tablet saves more power compared to other display technologies (such as LCD), and Information is always on display.

      What is the battery life estimate for the tablet?

      The battery life estimate of the tablet is one year. Further device configurations like increasing the active work hours of tablet, frequency of room status downlink, or excessive usage could impact this estimate negatively.

      What do the LED on the tablet’s corners mean?

      All four corners of the enclosure are exposed to let the LED colors help visualize the specific rooms state. Red and Green are set by default to represent occupied and available status, respectively. This setting is user configurable.

      For battery-powered tablets, this LED function is turned off to save power.

      How often does the tablet update room status?

      By default, the tablet requests for update on room status (Available/Occupied) every ten minutes.

      This can be configured to suit organizational needs but doing that will impact the battery life of the tablet.

      Can I have different room settings for different meeting rooms?

       

      The tempo application supports flexible settings for different meeting rooms to reflect the nature of use or amenities present in the room (such as Projector, Whiteboard, TV etc.).

      An example is a shared space that is used as a meeting room for some parts of the workday and an office for the remaining part, you can easily set the active hours of a room to reflect this arrangement.

      How are false bookings calculated?

       

      The solution includes a smart room sensor (PIR) that has motion detection capabilities. If no motion was detected within the duration of a booked meeting, the application reports this as a false booking.
