NEXT18 (NEM 662)

The purpose of this new interface is to provide a safe and secure miniture decoder connection for N, TT and small HO models.
The NEXT18 interface will control both DC and Coreless motors and provides electrical connections for up to 7 function outputs (F0 + AUX1-AUX6).  Manufacturers are free to use as many of thes connections as they want.  Any connections not used may be left unconnected in the loco circuit board.

The 18 pins are arranged symetrically so that if a decoder is installed the wrong way round then no damage will occur.  This arrangement also means that track power and ground connections are duplicated to increase the current that may flow through them and for a more reliable connection.    Each pin can carry 0.5amp so track pick up can be 1.0amp and ground can also be 1.0amp (Because 2 contacts are used) all other connections will be 0.5amp maximum.
