Seperate output for lights (direction dependant).
F4 can be used to switch the delay on/off if desired.
F3 can be used to switch between normal and shunting
speedtable if desired.
F3 can be used to switch speed-dependant steam on/off if
Output for AC and DC motor.
Secondary address. Can be turned on/off during on-track
The decoder will NOT work on analog
How it works:
The heart of the
decoder is a PIC16C84 chip containing software for decoding the track signal and
controlling the motor and the accessories. The decoding
of the digital signal from the track is made on the basis of the fantastic
document by Andrea Scorzoni: The manual of the
new Märklin-Motorola format. So in addition to
understanding the new format, the decoder also uses the
information contained in the new format, in particular the absolute direction
information. The direction is stored in nonvolatile
memory, so the decoder doesn't forget this info when power is removed.
Especially important for those using the old format only. Max. motor current 1A, max. current for F1 - F3 is 1A each, max. current
for AUX is 200mA. The total current must not exceed 1.5A, as this is the rating
for the diodes in the rectifier bridge.
