WIRING - LIONEL TMCC CONTROLER

R RalphOGR Forum Member

I am doing some re-work on my layout---swapping in/out some controlers --- which includes a number of BPC, ARC, TPC, AMC, etc controllers. Initially I have wired them as the documentation suggested, 'daisy chained', so two power wires and two data wires go from each controller to the next, beginning at the power source transformer for power and the command base for data and ending at the last controller in the line.

 

It would suit me better in the re-work if each controller were wired separately and the wires from each controller came back to a central source, and there pigtailed to either the base or the power source. 

 

Question, must they be daisy chained or can they be each, in a sense, individually wired to the base and power source.

 

Thanks in advance

 

Ralph

So each controller has inputs for power, dat & com, but not output connections, and 'home runs' back to the source for the inputs?  I see no reason why it wouldn't work that way.  Maybe set up two controllers to start with and doublecheck.  As long as they are getting power and the dat & com are all connected, it should be fine I would think.

The Lionel "daisy chain" is in essence just a parallel connection of all the devices.  It is not a chain where the signal goes through the first device to feed the second, etc.

 

Your home runs will work just fine.

 

(The only advantage of a daisy chain is that the total amount of wire might be less, and this could reduce the amount of capacitive load on the Base driver.)

Thanks William/Dale. 

I think the amount of wire will be about the same, in linear distance.

 

Unlike the neatness of Mike CT and others, my TMCC devices are not easily reachable to adjust the wiring. The small screw's and all the reaching to insure good connections will be a real pain in the back.

 

thanks again

Ralph
