public class LnSensorAddress
extends Object

Utilities for handling LocoNet sensor addresses.

There are three addressing spaces for LocoNet sensors:

• The space used for DS54 inputs, where the least-significant-bit in the address refers to the "Aux" and "Switch" inputs. These are represented by system names of the form LSnnnA and LSnnnS respectively. nnn is then the turnout number of the DS54 channel.
• The space used for BDL16 inputs, where the card and section numbers are part of the address. These are represented by names of the form LScccA1 through LScccA4, LScccB1 through LScccB4, and on through LScccD4. ccc is the BDL16 card number.
• A straight-forward numeric space, represented by LSmmm. Note that this is a 1-4096 scheme, not a 0-4095.
