Potrebujeme to rozlisit od sbernice, ktera na pinech 1 a 6 pouziva RailSyn, teda zeslabeny signal DCC.

Uz mame jednu znicenu centralu a bylo by dobre se vyhnout dalsim chybam.
Kdybys nebyl slabý duchem a používal jsi klávesnici a hlavu pak by se podíval sem:

LocoNet PowerThe LocoNet system has the following voltages and currents:
The command station has a 15mA pull-up, with a nominal 12V on the DATA signals (This is the LocoNet Termination).
Input impedance of a LocoNet device must be more than 47kOhms. This allows a max draw of 100uA at the minimum voltage.
Minimum voltage is 5V
It would require about 150 LocoNet devices to load the network to its maximum. This is much more than most layouts would have.
What are the Wires used for?
The wires in the LocoNet cable are used for the following signals (referenced to the pins on the connectors).
Pin Signal Voltage Colour
1 Rail Sync Positive (B) 7VDC White
2 Ground 0 Black
3 LocoNet 14.5VDC Red
4 Green
5 Ground 0 Yellow
6 Rail Sync Negative (A) 7VDC Blue
Colours can vary depending on the cable manufacturer.
RailSync is a differential signal, measuring from pins 1 to 6 should read 0V. Measure to Ground pin to determine voltage.
LocoNet B has the RailSync signals present for a Booster, limited to 200mA of current.
LocoNet T will have 12VDC/500mA present on pins 1 and 6 for powering throttles and other LocoNet devices, measured to the ground pin.
For this reason, boosters must be connected to LocoNet B.
Utility panels (LocoNet T) use a diode matrix to derive the needed 12VDC from the RailSync lines, which is provided to the front jacks.
Takže opravdu Zdenoušku není třeba nic vymýšlet
A zejména nematlat jsem nějaká X rozhraní !!!
