PRODUCT DESCRIPTION

The Powercast TX91503 PowerSpot® RF Wireless Power transmitter is specially designed to provide both power and data to end devices containing Powercast’s power harvesting technology. The PowerSpot transmitter contains a receiver that can hear when a Powercast-enabled harvesting device is in range, allowing it to stop power transmission when no harvesting devices are around. The transmitter can also be controlled by the PowerSpot app that can control periods of use. The PowerSpot transmitter is housed in a durable plastic case with several mounting options. Operational power is provided to the DC power connector, and there is a status LED to provide feedback on the transmitter’s functional state. This device has a factory set, fixed power output of 3W EIRP.

SET-UP AND OPERATION

  1. Mount the PowerSpot Transmitter at the back of a desk, counter or other area where you store your devices when not in use to create a PowerSpot recharging zone. Keyholes are also available on the rear of the transmitter case for wall mounted applications.
  2. Plug the DC connector of the power supply into the connector on the side of the transmitter. Plug the power supply into a standard 120V outlet.
  3. The PowerSpot transmitter will remain off until one of the following occurs:
    • An authorized device enters the PowerSpot recharging zone1.
    • The button on the unit is pressed to recharge a device with a completely discharged battery. The unit will activate and transmit power for 30 minutes from a button press and then will turn off if an authorized device is not present.
  4. When the PowerSpot transmitter is active and transmitting radio frequency (RF) energy, data is automatically included in the transmission and can be received and used to authorize the receiving device.

The status LED indicates the following operating conditions:

SNOOZE SETTING AND FIRMWARE UPDATES

Snooze setting for the PowerSpot transmitter:

  1. Setting a Snooze time allows the user to set up to four time periods where the transmitter will remain OFF, even if a device within range requests a charge
  2. Using the PowerSpot app, navigate to the Snooze tab
  3. Enter the transmitter ID found on the back label of your transmitter
  4. Select the “+” button to add events
  5. Choose a start and end time for your event(s)
  6. After adding desired events, hit “Set Snooze”
  7. The app will report that the Snooze has been set successfully or not
  • Note: The PowerSpot transmitter will not transmit the RF energy that is used for power and data as described above while the Snooze is being set.
  • Note: When setting the Snooze, the transmitter’s time is automatically synced with the time of the mobile phone.
  • Note: If power is disconnected from the PowerSpot transmitter, any previously set Snooze will be deleted.

Time re-syncing for the PowerSpot transmitter:

  1. To re-sync the PowerSpot transmitter’s time with the mobile phone, navigate to the “Snooze” tab in the PowerSpot app
  2. Enter the transmitter’s ID and hit “Sync Time”
  3. The app will report that the time has been set successfully or not

If a firmware upgrade is available for the PowerSpot transmitter:

  1. Unplug the power to the PowerSpot transmitter
  2. Press and hold the top button down
  3. With the button still pressed, plug the transmitter back in. Once powered on, the LED will be solid green and you can let go of the button
  4. Within 2 minutes, navigate to the “Scan Devices” tab of the PowerSpot app. “PowerSpot” with a download icon should be available. Tap the download icon and then “Upgrade” to begin the firmware update.
  5. Once the upgrade is complete, the app will report “Done”.
    Note: If the PowerSpot transmitter is not connected to the app within 2 minutes, it will automatically return to normal operation.
    Note: The transmitter will not transmit the RF energy that is used for power and data as described above during a firmware upgrade.

To determine the current firmware version of your transmitter:

  1. Press and hold the button on the top of the PowerSpot transmitter for at least 5 seconds
  2. Continue holding the button and utilize the “PowerSpot” app on the “Scan Devices” tab to determine the firmware version
    Note: The PowerSpot transmitter will stop communicating the firmware version and return to normal operation when the button is released.
