```
public class AcelaNode
extends AbstractNode
```
Models an Acela node.
Nodes are numbered from 0. The first watchman node carries the first 8 sensors 0 to 7, etc.
The array of sensor states is used to update sensor known state only when there's a change on the serial bus. This allows for the sensor state to be updated within the program, keeping this updated state until the next change on the serial bus. E.g. you can manually change a state via an icon, and not have it change back the next time that node is polled.
Same applies to the outputs (Dash-8s and Signalmen)

    createInitPacket in class AbstractNode
    
    Returns:
    
    the packet, or 'null' if not needed
  - createOutPacket
```
public AbstractMRMessage createOutPacket()
```
    Create a Transmit packet (SerialMessage) to send current state.
    
    Specified by:
    
    createOutPacket in class AbstractNode
    
    Returns:

  - markChanges
```
public void markChanges(AcelaReply l)
```
    Use the contents of the poll reply to mark changes.
    
    Parameters:
    
    l - Reply to a poll operation
  - registerSensor
```
public void registerSensor(Sensor s,
                           int rawaddr)
```
    Register a sensor on an Acela node. The numbers here are 0 to MAXSENSORBITS, not 1 to MAXSENSORBITS.
    
    Parameters:
    
    s - Sensor object
    
    rawaddr - index number of sensor's input bit on this node, valid range from 0 to MAXSENSORBITS
  - handleTimeout
```
public boolean handleTimeout(AbstractMRMessage m,
                             AbstractMRListener l)
```
    Deal with a timeout in the transmission controller.
    
    Specified by:
    
    handleTimeout in class AbstractNode
    
    Parameters:
    
    m - message that didn't receive a reply
    
    l - listener that sent the message
    
    Returns:
    
    true if initialization is required
  - resetTimeout
```
public void resetTimeout(AbstractMRMessage m)
```
    A reply was received, so there was no timeout, do any needed processing.
    
    Specified by:
    
    resetTimeout in class AbstractNode
    
    Parameters:
    
    m - message received that has reset the timeout and is waiting to be handled
