hi all, i have a wired distant signal (4 wires for the 2 green and 2 red lights, plus the common wire, viessmann 4030), and i am getting mad in order for it to function properly with rocrail. i tried everything i could, but something is always off. it seems to only change one light at a time, so there is no way to switch from 2 yellow lights to 2 green lights. i have wired it to a basic signal decoder (ldt 8x2), basically i have 2 addresses and each of them is like a 2 aspect signals, in fact i control all my basic 2 aspect signals with those decoders. so i thought that by just defining a distant signal in rocrail (which seems to have been properly created, it reports 3 aspects), and putting the 2 addresses in the interface section (red:address1-red, green: address 1-green, yellow:address 2-red, and also white:address 2-green, even if white is clearly not used as an aspect). I did this type of configuration for marklin 24624, and it's ok with it. but no. Please help, i tried to look at the documentation and in the forum, but i cannot find any help. thanks

Hi Fab
With Rocrail one possibility is:
- to use a 60842 (a set of four relays) operated by digital orders. You need one of the four relays to control the distant signal
- you declare this "signal by giving it a name, an address, a protocol and if multiple central stations, indicating which one controls it
- in a Block in the SIGNAL TAB, you may give the name of the main signal and also the name of the forsignal
- when Rocrail sets the block to green it will set both the main signal and the advance signal to green-green

About the Viessmann 4030
- it is a distant lDB Light signal using LEDs, with a common wire ( a diode to the +16 VDC power supply)
- you have 2 wires with resistors for the green LEDs and two wires with resistors for the redLEDs
- you must wire both RED LED resistors tpogether and apply a O VDC controlled by you M84 (60842) RED output
- you must wire both GREEN LED resistors tpogether and apply a O VDC controlled by you M84 (60842) GREEN output
- you must connect the middle output (switch over) to the ground of your DC supply.

Cheers
Jean

I also use the LDT 8x2, but let the distant and main signals share decoder outputs, in order to limit the number of outputs required, and simplify PC software programming.

thx, i also found another solution : i do not compile the interface tab of the distant, i created 2 dummy block signals interfaced to the ldt where the distant is connected, and then i created 4 actions to set those 2 block signals green and red, and lastly in the distant actions tab i set, for each state green red yellow, the call to the proper set of 2 actions that set the distant leds accordingly. i just was hoping that there was a faster way.
