Frequently Asked Questions
Q:
Is the polarity of the signal input important?
A:
No, the signal input is isolated by an optocoupler.
Q:
Is the polarity of the power input important?
A:
No, the power input has a rectifier.
Q:
My decoder is not programmable via POM on my Lenz control unit
A:
Make sure that both locomotive addresses on the unit are set to address 9999.
Q:
Can the decoder switch Conrad points motors directly?
A:
No, for that you need a DR4101. (See connection examples on page 10).
Q:
Can the decoder directly switch so-called common min signals (common cathode)?
A:
No, for that you need a DR4103.
Q:
Can the decoder directly switch so-called common plus signals (common anode)?
A:
Yes, that's not a problem because common anode is standard in model building.
Q:
Does the decoder have a built-in series resistor for the signals?
A:
No, you have to connect the resistor supplied with the signal to terminal C.
Q:
When programming / reading the CV, my unit shows "error". What's going on?
A:
The decoder has a power buffer for switching coil actuators, which has to be loaded first.
Try reading / programming again (several times if necessary)
