A method includes receiving a token over a token line at a first control module and, in response to receiving the token, receiving a first address. The first control module is configured to control one or more first actuators. The method also includes using the first address for communications over a communication line and identifying a second address. The method further includes providing the token over the token line to a second control module, where the second control module is configured to control one or more second actuators. In addition, the method includes providing the second address to the second control module in response to the second control module receiving the token.

1. A method comprising: receiving a token over a token line at a first control module that has not yet been assigned a first address for communications over a communication line, the first control module configured to control one or more first actuators;in response to receiving the token, receiving the first address for the first control module;using the first address for communications involving the first control module over the communication line;receiving a ping directed to the first address over the communication line while the first control module has the token, the ping including a request to identify a current software version of the first control module;providing the token over the token line to a second control module that has not yet been assigned a second address for communications over the communication line, the second control module configured to control one or more second actuators;identifying the second address for the second control module; andproviding the second address to the second control module in response to the second control module receiving the token. 2. The method of claim 1, further comprising: using the second address at the second control module for communications over the communication line;receiving a second ping directed to the second address over the communication line while the second control module has the token, the second ping including a request to identify a current software version of the second control module;providing the token over the token line to a third control module that has not yet been assigned a second address for communications over the communication line;identifying the third address for the third control module; andproviding the third address to the third control module in response to the third control module receiving the token. 3. The method of claim 2, further comprising preventing the first control module from receiving the token from the second control module. 4. The method of claim 1, wherein identifying the second address comprises incrementing the first address to produce the second address. 5. The method of claim 1, further comprising: communicating a current software version associated with the first control module in response to the ping. 6. The method of claim 5, further comprising: receiving a software update in response to the communication of the identified current software version. 7. The method of claim 1, further comprising: receiving control signals at the first control module, the control signals directed to the first control module using the first address; andopening and closing the first actuators based on the control signals. 8. A system comprising: multiple actuators configured to release a material;multiple control modules configured to control the actuators; anda token line and a communication line coupling the control modules;wherein a first of the control modules is configured to: receive a token over the token line while the first control module has not yet been assigned a first address for communications over the communication line;in response to receiving the token, receive the first address for the first control module;use the first address for communications over the communication line;receive a ping directed to the first address over the communication line while the first control module has the token, the ping including a request to identify a current software version of the first control module;provide the token over the token line to a second of the control modules while the second control module has not yet been assigned a second address for communications over the communication line;identify the second address for the second control module; andprovide the second address to the second control module. 9. The system of claim 8, wherein the first control module is prevented from receiving the token after the first control module has received the first address. 10. The system of claim 8, wherein the first control module is configured to identify the second address by incrementing the first address received by the first control module. 11. The system of claim 8, further comprising: at least one of a controller, a processing device, and a wireless junction configured to generate the ping. 12. The system of claim 8, wherein the first control module is further configured to: communicate its current software version in response to the ping; andreceive a software update in response to the communication of the identified current software version. 13. The system of claim 8, further comprising: a controller configured to provide control signals to the control modules, the control modules configured to open and close the actuators based on the control signals. 14. The system of claim 13, further comprising: a wireless receiver configured to receive wireless positioning signals; anda processing device configured to determine a position associated with the actuators based on the wireless positioning signals and to determine whether to open or close the actuators based on the determined position;wherein the controller is configured to provide the control signals to the control modules based on signals from the processing device. 15. The system of claim 14, wherein the processing device is configured to determine whether to open or close the actuators by determining whether the material has already been released at the determined position. 16. The system of claim 14, wherein the controller is further configured to: estimate a speed of a vehicle on which the system is being used; andprovide the control signals to the control modules based on the speed of the vehicle. 17. An apparatus comprising: a first controller configured to: control one or more first actuators;receive a token over a token line while the first controller has not yet been assigned a first address for communications over a communication line;receive the first address for the first controller in response to receiving the token;use the first address for communications over the communication line;receive a ping directed to the first address over the communication line while the first control module has the token, the ping including a request to identify a current software version of the first control module;provide the token over the token line to a second controller that has not yet been assigned a second address for communications over the communication line, the second controller configured to control one or more second actuators;identify the second address for the second controller; andprovide the second address to the second controller; andat least one interface configured to communicate over the token and communication lines. 18. The apparatus of claim 17, wherein the first controller cannot obtain the token from the second controller. 19. The apparatus of claim 17, wherein the first controller is configured to identify the second address by incrementing the first address. 20. The apparatus of claim 17, wherein the first controller is further configured to: communicate a current software version associated with the apparatus in response to the ping; andreceive a software update in response to the communication of the identified current software version. 21. The apparatus of claim 17, wherein the first controller is further configured to: receive control signals directed to the first address; andopen and close the one or more first actuators based on the control signals.
