Cota WPT System User Manual 1 Product Description COTA WIRELESS POWER TRANSFER SYSTEM USER MANUAL 1 PRODUCT DESCRIPTION The Cota Wireless Power Transfer system (Cota WPT system) transmits power by using radio waves in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band defined by the FCC. The Cota WPT system constantly communicates with the Cota Wireless Power Transfer Client (Cota WPT client) to identify paths along which power can be delivered, and sends power along these paths. Power may be delivered up to a maximum distance of 1 meter from the front of the Cota Tx203 Power Source (Cota Tx203 power source). The Cota WPT client is designed to receive RF power from a Cota Tx203 power source and may be used to provide stable power to a variety of devices through its 5 V USB port. The Cota WPT client may be placed on a table-top or mounted on a wall or other stable surface. 2 SET-UP If the Cota Tx203 power source can be installed on a wall or suspended from the ceiling. Installation should be performed by qualified contractors and electricians. Such installations must ensure adequate ventilation around the rear panel of the Cota Tx203 power source. For tabletop use, place the Cota Tx203 power source in the provided table stand. A VESA mount may be used to secure the Cota WPT source to a stand or wall. Ensure that the Cota Tx203 power source is secured and cannot fall. Avoid tripping hazards by ensuring proper placement of the AC power cable or the Ethernet cable, when powering through power-over-Ethernet

(PoE). The Cota WPT client shall be placed within 1 meter of the front of the Cota Tx203 power source and at no more than a 60 offset from the front of the Cota Tx203 power source. 3 OPERATING THE COTA TX203 POWER SOURCE AND COTA WPT CLIENT Plug the Cota Tx203 power source into an AC wall outlet and apply power. The light ring on the Cota Tx203 power source should illuminate, changing colors slowly and continuously while the Cota Tx203 power source is initializing. For light ring colors and their meanings, see Section 4, Light Ring Status. 3.1 PERFORM POWER NETWORK CHECK 1. Connect to the Cota Tx203 power source by using the internal Wi-Fi hot spot (preferable) or the companys LAN network and Cota power transmitters Ethernet. 2. Log in to the Cota Desktop Utility (Cota DTU) interface by using the power transmitters Wi-Fi, for example Tile_51 with ossiawifi as the password.

Cota WPT System User Manual 4 Light Ring Status 3.2 ENABLE COTA TX203 POWER SOURCE OPERATION 1. In the Cota DTU >> System Status window, verify that all the components are showing the correct values. The Cota WPT clients are factory registered with your Cota Tx203 power source and will appear in the Receiver List window. 2. Select the desired Cota WPT client and click Start Charge. 3. When shutting down the Cota Tx203 power source, first click the Shutdown command button in the Cota DTU Debug Commands window, and then wait for 30 seconds before disconnecting the Cota Tx203 power source from AC power. LIGHT RING STATUS 4 State Light Ring Color Pattern Description Idle/Debug Slowly flashing orange Calibration Purple segments progressing Wait for Power Receivers Light red background color with one bright light segment moving slowly in circle Ready Green background color with one pink light segment moving in circle The system is in Idle or Debug state where the HostMCU Firmware stops discovering the power receivers, performing power receiver queries, or scheduling TPS. The HostMCU Firmware, however, still handles new commands and asynchronous messages from power receivers. The system enters this state when the Pause command is used at the command line interface (CLI) or in the Cota DTU. The system also remains in this state if the Debug Mode parameter is set to true in the Cota_Config.json file. To exit this state, enter the Run command at the CLI or in the Cota DTU. The system is performing power transmitter calibration and initialization. The power transmitter enters this state automatically upon starting up, but users can also initiate a manual calibration in the Cota DTU. The power transmitter has been initialized and calibrated, but it does not detect any power receiver devices within the vicinity. The power transmitter detected at least one power receiver and is ready to deliver power to that power receiver, however, the power receivers might not have been authorized or enabled to receive power. Users can use the Cota DTU to register and enable power delivery.

(Continued) State Running TPS Multiple rings (magenta color on the power transmitters) and light patterns moving quickly in circle Identifying Solid green color ring flashing every second Light Ring Color Pattern Description The system is delivering power to power receivers. Users can use the Cota DTU to locate the power transmitter. Upon clicking Identify Transmitter in the Cota DTU, the light ring will flash for at least 15 seconds (configurable duration); this capability allows users to associate the Cota DTU with the physical power transmitter. The power transmitter has encountered an error and cannot continue without intervention. All critical errors will force the power transmitter to enter this state. Users should check the power transmitter log and power transmitter temperature for more information about the error. The log files can be viewed in the Cota DTU window.
