Slave Node Position Detection (SNPD) Ie Autoaddressing
These methods allow the detection of the position of slave nodes on the LIN bus and allow the assignment of a unique node address.
- Allows similar or the same devices to be connected on the bus without end of line programming or connector pin programming.
Restrictions:
- All auto-addressing slaves must be in one line
- Standard slaves can be connected in any way

Famous quotes containing the words slave and/or position:
“Do not discourage your children from hoarding, if they have a taste to it; whoever lays up his penny rather than part with it for a cake, at least is not the slave of gross appetite; and shows besides a preference always to be esteemed, of the future to the present moment.”
—Samuel Johnson (1709–1784)
“He who is usually self-sufficient becomes exceptionally vain and keenly alive to fame and praise when he is physically ill. The more he loses himself the more he has to endeavor to regain his position by means of the opinion of others.”
—Friedrich Nietzsche (1844–1900)
