The CT301 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.

The CT301 radio module can be mounted with two 2.5mm machine screws. It is preferred that the screws and stand offs are made of 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 connector J3 and J5.

Normal addressing can be used to send data to a Chameleon device. 1 - 63 data bytes may be appended. N is the address of the Filter n paired to the other device. The address n is 1 hex digit. The address n=0 is the own address of the device

Extended addressing can be used to send data to a specific WPS address. The address specifier has to consist of 4 hex digits.

TEST commands

Stop pairing for new devices (only for coordinator/Laser).

Discover all lasers/coordinators by PAN ID. Only the lasers supporting this feature are answering to it. The list may contain max. 32 devices, sorted by signal strength (strongest first) and can be read by 0/PAIR/ELEMENT command.

The command needs always the same time to check all channels (the request is repeated a few times on each channel).

Command does not unpair the current connection, but the live line transmission shall be disabled before calling NETLIST.

Reads one entry at a time from discovery list (generated by 0/PAIR/NETLIST command).

The id is the 16bit PAN ID of the laser. s is the signal strength.

Selects a laser. The id is the PAN ID of the laser. OK is only a immediate acknowledge. hhhh is a optional user value transmitted to laser. Command also enables the visual feedback on laser (by a periodic request every

0.5s). For keeping visual feedback the sleep of the node must be prevented by a “\n” or by repeating the command. The visual feedback is disabled on: sleep, any other command from host, UNSELECT command.

Command does not unpair the current connection, but the live line transmission shall be disabled before.

Start pairing sequence with laser device, previously selected by SELECT command. It is stored to NV memory (exactly the same as regular pairing). The previous connection is lost. On successful pairing the message 0/PAIR/n is shown on coordinator/laser.

Returns the 16bit PAN ID of the paired device (paired by 0/PAIR/START or 0/PAIR/CONFIRM). 0/ERR if not paired.

Asynchrony commands

request for (visual) feedback on coordinator. hhhh is a user value from application of node. Laser application does not need a timeout for selection: a 0/UNSELECTED will always come after a timeout.

messages on node/combo during (visual) feedback. An initial SELECT_ACK is sent on the first acknowledge from coordinator/laser. SELECT_LOST is sent if the coordinator does not acknowledge anymore (to the periodic request from node). And ACK again if the coordinator is responding again.

The radio module is ready to receive data via UART or transceiver after sleep mode or power-up.

The WPS crashed. This event occurs twice. The first error gives the file number and the second gives the line nr that caused the crash.

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:

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 Module FCC ID: RFDCT301” or “Contains FCC ID: RFD-CT301”. 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 equipment authorization.

Installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance.
