  • the rules described below are with regard to splitters having two outputs. However, as will be described, the exemplary rules may be modified for use with splitters having any number of outputs or even a combination of the splitters having different numbers of outputs.
  • Rule 1 A first exemplary rule (hereinafter referred to as "Rule 1") may be directed to how the light nodes operate. Specifically, Rule 1 may define that when a light node detects that the address signal is asserted continuously for some fixed period, t, on the address line 405, the light node transmits data on the bus 410 to establish a system specific commission process. This results in the assignment of a system address relative to the light node's sequential position on the string or tree structure. As noted above, only a single light node is commissioned at a time. Thus, the light node (e.g., light node 325A) that is being
  • Rule 1 determines the address signal is continuously asserted on the address line 405 (e.g., the address line 405 goes "high" continuously for t) and utilizes the bus 410 to return data that the light node has identified that it is being commissioned.
  • Rule 1 may include a further operation. Specifically, when the light node has transmitted the data back to the controller device 120 on the bus 410, the light node may utilize the output on the address line 405 to forward for subsequent address signals being received.
  • Rule 2 may also be directed to how the light nodes operate. Specifically, Rule 2 may define that when a light node detects a signal pattern on the address line 405, the light node simply repeats the signal pattern on the output of the address line 405 and takes no further action. Since the signal pattern is associated with splitter operations, the light nodes may simply ignore the signal pattern and perform only a forwarding operation. As will become apparent below, Rule 2 may assume that the light nodes utilize the output on the address line 405 since the light nodes receiving the signal pattern are already commissioned.
  • Rule 3 may be directed to how the splitters operate. Specifically, Rule 3 may define that when a splitter detects the address line 405 asserted continuously for some fixed period with the address signal (without any splitter signal having been received), the splitter ignores the signal. By the splitter ignoring the address signal when asserted continuously, the splitter may cause a time out to occur as no return data is transmitted back to the controller device 120. For example, when a final light node on a light string is commissioned, the address signal continues to be transmitted since the final light node on the light string will forward the address signal on the output of the address line 405.
  • the address signal that is being received by the splitter is ignored. This means that the controller device 120 will receive no return data in response to the address signal and the address signal time out will occur. As described above, the controller device 120 may transmit the splitter signal when the time out is determined. Rule 3 may include a further condition. Specifically, when the splitter has received a splitter signal, the splitter may then repeat the address signal on the identified output defined in the splitter signal. In this manner, only splitters that have not yet received a splitter signal ignore the address signal.
  • the time outs occurring based on the address signal may be used by the controller device 120 in generating/transmitting splitter signals and also determining when the commissioning process has terminated. Specifically, as will be described in an example below, when each branch of the tree structure results in a time out of the address signal and the splitter signal, the controller device 120 may determine that the commissioning process has ended and addresses for all light nodes are assigned.
  • Rule 4 may also be directed to how the splitters operate.
  • Rule 4 may define how the splitters utilize an incoming splitter signal.
  • the splitter signal may include one or more segments.
  • Rule 4 may include two parts: Rule 4a when more than one segment is present in the splitter signal and Rule 4b when only one segment is present in the splitter signal.
  • Rule 4a when a splitter identifies a signal pattern on the address line 405 (e.g., a splitter signal) and when the data in the splitter signal is longer than one segment, the splitter determines the proper action based on the value of the last segment.
  • the bit pattern on the last segment of the splitter signal may be 01, 10, 11, or 00.
  • the splitter ignores the splitter signal. If the splitter signal is 01, the splitter removes the last segment from the splitter signal and forwards the signal pattern to a first output (e.g., output A). If the splitter signal is 10, the splitter removes the last segment from the splitter signal and transmits the signal pattern to a second output (e.g., output B). By removing the last segment, the splitter signal has one less segment and the last segment now on the remaining splitter signal is the second to last segment that was included in the splitter signal that was received by the splitter.
  • a splitter further downstream performs the same operation if the remaining splitter signal has two or more segments and utilizes the last segment in the remaining splitter signal.
  • Rule 4b when a splitter sees a signal pattern on the address line and when the data in the splitter signal is only one segment, the splitter determines the proper action based on this one segment. Again, in the case of a splitter with two outputs, the bit pattern on the one segment of the splitter signal is either 01, 10, 11, or 00. When the last segment is 11 or 00, the splitter ignores the splitter signal. If the splitter signal is 01, the splitter transmits the address signal to a first output (e.g., output A). If the splitter signal is 10, the splitter transmits the address signal to a second output (e.g., output B).
  • the controller device 120 may generate a bit pattern to accommodate the further output(s).

  • the next set of splitter signals relates to the output B of the splitter 305 and the outputs of the splitter 320.
  • the controller device 120 knows that there was a time out for output A of the splitter 320. Thus, the controller device 120 may ignore determining a third level splitter along this path. Instead, the controller device 120 may generate and transmit a splitter signal having a bit pattern of 01-10-10. Therefore, the splitter 305 receives this splitter signal, then removes and processes the last segment 10. The first remaining splitter signal is received by the splitter 320. The splitter 320 removes and processes the last segment 10. The second remaining splitter signal is passed through the light string 355. With no further splitter, a time out occurs for the splitter signal having a bit pattern of 01-10-10. Again, the controller device 120 transmits the splitter signal for the other branch (e.g., splitter signal having bit pattern 10-10-10) but determines a time out.

Although there are potentially sixteen branches that may be created with splitters having two outputs, the controller device 120 may omit fourteen of these branches due to the time outs registered with light string 340, output B of splitter 315, output A of splitter 320, and light string 355. Thus, the only pathway to be considered is through the light string 350. Accordingly, the controller device 120 may generate and transmit a splitter signal having a bit pattern of 01-01-10-01. When the splitter 305 receives this splitter signal, the last segment 01 is removed and processed. When the splitter 310 receives the first remaining splitter signal having a bit pattern of 01-01-10, the last segment 10 is removed and processed.

The third remaining splitter signal having a bit pattern of 01 is passed through the light string 350. However, with no splitter connected to the light string 350, a time out occurs. Again, the controller device 120 generates and transmits a splitter signal having a bit pattern of 10-01- 10-01 but this also results in a time out.
  • the controller device 120 may determine that the commissioning process has concluded. Specifically, all outputs of the first splitter level have further connections. Three of the four outputs of the second splitter level have further connections. Specifically, output A of splitter 320 has no subsequent connection. Thus, a time out from output A of splitter 320 concludes further analysis for branches along this pathway. Only one of the eight outputs of the third splitter level has further connections. Specifically, the light string 340, the output B of the splitter 315, and the light string 355 have no subsequent connections. Finally, none of the sixteen outputs of the fourth splitter level has further connections. When the controller device 120 has determined that all possible pathways on branches of the tree structure result in a time out, the controller device 120 concludes the commissioning process as all addresses of the light nodes in the lighting array 300 have been assigned.

  • the light node 325 A determines whether the address signal has been received for a fixed period t. As the output on the address line 405 for the light node 325A is not being used, only the light node 325A has received the address signal. In this manner, only one light node is commissioned at a time during the commissioning process according to the exemplary embodiments.

  • the controller device 120 determines whether a time duration after the response from the light node 325A has exceeded an idle time period. Since the address signal is continuously being asserted on the address line 405 and with the commissioned light node utilizing the output on the address line 405, any subsequent light node in series with the commissioned light node receives the address signal and transmits a response on the bus 410. However, when no further light node is present, there is no further response and the idle time exceeds a predetermined threshold.

  • the controller device 120 determines whether there are further splitter outputs. In this scenario, since no splitter outputs have been addressed, the controller device 120 determines that there are further splitter outputs. When there are further splitter outputs, in 535, the controller device 120 determines the splitter and splitter output to be used for the commissioning process. For example, the splitter may be splitter 305 and the splitter output may be the output A that is selected in the first splitter level. In 540, the controller device 120 generates and transmits a signal pattern that includes a splitter signal. As noted above, the address signal continues to be asserted on the address line 405.

  • the splitter 305 receives the signal pattern, the splitter 305 processes the splitter signal included in the signal pattern to determine how the splitter 305 is to direct any signal being asserted on the address line 405. In this scenario, with the splitter signal being 01, the splitter 305 directs signals to a first output (e.g., the output in which light string 330 is connected).
  • the address signal being asserted eventually reaches the light string 330, in particular to light node 330A.
  • the controller device 120 determines whether an idle time since the signal pattern was transmitted has exceeded a predetermined (or dynamically determined) threshold.
  • the threshold may be predetermined as a minimum amount of time that may be necessary for the splitter signal to reach a splitter and for any response to be received back from a light node.
  • the threshold may also be dynamically determined based on a distance for the splitter signal to travel as well as for a distance for a response to travel back to the controller device 120. Since there is a light string 330 that is connected to the first output, a response from the light node 330A is received by the controller device 120 over the bus 410 within the idle threshold. Since a response is received, the controller device 120 returns the method 500 to 510. In this manner, each of the light nodes 330A-F are
