1 INTRODUCTION

The CT100 radio facilitates a IEEE 802.15.4 based radio communication. It uses a proprietary wireless communication stack to implement a star or cluster network with multiple nodes communicating simultaneously.
The radio module provides three basic functions:
- Transparent communication between network node and network coordinator
- Writing parameters to the radio module for configuration to determine its mode of operation such as the configuration of a node or coordinator
- Reading parameters from the radio module
All communication to the radio module is established through a UART communication interface.

4 MODULE MOUNTING

The CT100 radio module can be mounted with two 2.5mm machine screws. It is preferred that the screws and stand offs are made of a non conductive and non-ferromagnetic material such as plastic or ceramics.
Alternatively the module can be directly soldered on to a carrier board utilizing the radio module using con nector J2 and J6.

6 RADIO MODULE CONFIGURATION

The radio module can be configured through filters using the command 0/CONF/FTR/n/hhhhhhhh, whereas n indicates the filter number and h the filter bit mask. Each filter corresponds to a node in the network where as filter 0 is reserved for the radio module configuration. Each bit in the mask has a dedicated function:
Bit range Bitmask Value Description
31-24 (Manufacturer Type)
23-16 (Device Type)
14-15 11-13
(Range Type Mask)
4-10 0-3 (Device Number)
The following section shows a example of UART configuration and pairing process: Configuration of Node 2
0/CONF/FTR/0/80135001<CR><LF> // Configure Node 2 0/CONF/FTR/1/8011D800<CR><LF> // Configure channel to communicate to coordinator
Configuration of Coordinator 0/CONF/FTR/0/80110000<CR><LF> // Configure Coordinator Device number must be 0 0/CONF/FTR/2/8013D801<CR><LF> // Configure channel to communicate to Node 2

7 CERTIFICATION

7.1 FCC Certification

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference that may cause undesired operation.
If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter M odule FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipme nt authorization.
Installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance.
