KENALL TEKLINK TL200 BLE Radio Module User Manual

KENALL TEKLINK TL200 BLE Radio Module

Summary:
This document covers the usage and operation of the Kenall TL200 BLE (Bluetooth Low Energy) radio module for use in a TekLink wireless lighting control system. The TL200 will only be used in Kenall lighting products that offer TekLink wireless controls as an option. The module is not intended for general sale.

OVERVIEW

The Kenall TL200 radio module will be factory installed as the TekLink control module for use in a wireless mesh lighting control system. The TL200 radio module will be installed in each LED luminaire. The TL200 can be used in indoor and outdoor lighting applications. Optionally a TL200 radio module can be added as a primary site controller that can interconnect to other Kenall TekLink family lighting products (e.g., Kenall TekLink TL1000, TL2000 systems).

The Kenall TL200 Bluetooth Low Energy (BLE) radio transceiver module supports the Bluetooth Low Energy radio data protocol in the 2402-2480 MHz ISM radio band. The module will operate on the 40 channels allocated in this ISM band. The TL200 is comprised of a printed circuit assembly and a connected antenna. The module is intended to be used in the USA. There are no other supported or non-supported capabilities for any other country.

The module will not be for sale to the public or be made accessible by users of Kenall products. The module does not directly support software debugging or messages that could allow unauthorized users to modify the software or adjust radio settings that could affect compliance. The host devices that interface with this radio module are proprietary to Kenall. Only proprietary software written and distributed by Kenall can be installed on the TL200. Source code (both firmware and/or software) is solely controlled by Kenall and not distributed to end users.

For safety, power off TekLink luminaires with TL200 radio modules prior to disassembly and servicing.

For optimal coverage, the antenna will be mounted vertically (length-wise) inside the luminaire in a location with minimal metallic obstructions.

APPLICATIONS

The initial application for the radio module is for Kenall TekLink 200 series LED lighting products. When commissioned and placed into service, the TL200 radio modules will communicate with data packets in a BLE mesh network configuration. The TekLink lighting system will detect occupancy via a sensor and adjust lighting levels per configuration settings.

After luminaire installation, a Kenall tablet app (Android or IOS) will allow the end user to modify the factory default lighting modes of the luminaires (e.g., occupancy timeouts and zones, dim levels, repeater mode, etc.). The end user can also lower the transmitter power level to reduce interference, but no other changes to the BLE radio operation are permitted.

BLOCK DIAGRAM

MECHANICAL DIMENSIONS AND CONNECTORS

The TL200 module will be embedded in Kenall lighting products that offer TekLink wireless controls as an option. No connectors will be accessible by the end customer. Please contact Kenall to request pin-out information – requires NDA. Dimensions are in inches.

PROGRAMMING

FACTORY PROGRAMMING AND COMMISSIONING
The TL200 is programmed and commissioned in the Kenall factory on a per-order basis. Proprietary application software is programmed into the flash memory of the TL200 processor using a programming pod connected with an adapter to J1 on the TL200. For a given customer purchase order, custom radio module settings, and security keys are commissioned (over BLE) by Kenall factory production prior to shipment. Default lighting parameters (occupancy zones and timeouts, dim level, repeaters, etc.) are also set by the factory.

There is no host bootloader or JTAG interface accessible for uploading new software to the TL200 by a customer. After factory programming, a security bit is set to prevent readout or modification of the code from the debug port.

CUSTOMER SETTINGS
The end user of the Kenall luminaire with the TL200 controller will have the option to adjust lighting modes: e.g., occupancy zones and timeouts, dim levels, repeaters, and related settings after installation, they will not be able to directly modify the radio operation.

FIELD UPGRADE
The TL200 will support OTA (wireless over-the-air) code updates from a BLE- capable tablet or mobile phone running a proprietary Kenall software app. The TL200 code image will be sent from a tablet via BLE to the TL200 module. This will typically be done by Kenall service technicians. TL200 code cannot be read out using an OTA update.

REGULATORY TESTING AND CONFIGURATION

The TL200 can be loaded with a test code to put the radio into different constant transmission or reception states to verify the end device does not emit spurious emissions. The TL200 module can be placed into various test modes using CLI commands issued from the serial port (J1). The test code and CLI commands are proprietary to Kenall, please contact Kenall Manufacturing for further info.

FCC Modular Usage Statement

• Note 1: This module is certified and complies with RF exposure requirements under fixed conditions; this module will only be installed in fixed applications.
  To comply with FCC RF Exposure requirements, this device must be installed such that a minimum separation distance of 20cm is maintained between its antenna and all persons during normal operation. Luminaires are typically mounted overhead and away from nearby people. This should limit their exposure to the RF signals transmitted by the radio module. A fixed device is defined as a device that is physically secured at one location and is not able to be easily moved to another location.

• Note 2: Host product manufacturers must provide in their user manual the required RF exposure information for mobile & fixed usage of this module. Host product manufacturers must use the following RF exposure statement in their user manual “This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 cm between the radiator and all persons. This transmitter must not be co-location or operating in conjunction with any other antenna or transmitter.”

• Note 3: Any modifications made to the module will void the Grant of Certification, this module is limited to OEM installation only and must not be sold to end-users, end-user shall have no manual instructions to remove or install the device, only software or operating procedure shall be placed in the end-user operating manual of final products. Changes or modifications not expressly approved by Kenall will void the user’s authority to operate the TekLink luminaire that incorporates this TL200 radio module.

• Note 4: Additional testing and certification may be necessary when multiple modules are used.

• Note 5: The module may be operated only with the two external antennas with which it is authorized. Refer to Appendix A.
