Dekooderit/Oheislaite- ja funktiodekooderit

Accessory and function decoders can be classified into different types: function decoders for locos and cars understanding the new motorola 2 format, function decoders for locos and cars understanding the old motorola 1 format, stationary decoders for turnouts and accessories.

The 60960 loco function decoder

chip	701.22
functions	f1, f2, f3, f4
addresses	80 adr., DIP switch
size	24 × 18 × 8 mm

Function decoder for locos and cars understanding the new motorola 2 format. Since 1997. Makes the four functions f1 - f4 available.

By adding two transistors BST 51, and three resistors (2 * 47k and 3,9 Ohm), the 60960 can be extended to a 60961, which additionally has direction dependent light functions. The conversion becomes obvious from comparing photos of both decoders.

The 60961 loco directional function decoder

chip	701.22
functions	f0, f1, f2, f3, f4
addresses	80 adr., DIP switch
size	24 × 18 × 8 mm

Function decoder for locos and cars understanding the new motorola 2 format. Since 2001. Principally identical to a 60960, but with additional direction dependent outputs, suitable e. g. for directional headlights.
