Help With crossover


 

Hi Members
Could someone please help me out with A Single crossover and JMRi
?
First things first.
Please take a look at this photo of the Crossover
I presumed that one turnout has one Block so A Crossover just needs 2.
Is that correct?
Each end of the 4 crossover ends i have isolated,Power is feed to the small joins attached to the(each side) crossover(2) to make 2 blocks with sensors
Is that correct?
?
My problem comes when i choose single LH Crossover in JMRI then when i go to set masts it ask for 4 Blocks,but i only have 2
Can someone explain the Four please?
?
Appreciate your time
regards Brett

Brett,

Your configuration looks correct.

While it is possible to specify up to four blocks, the normal process is to use one block for the first two entries and one for the other two entries.

Sometimes, for historical reasons it is not possible to treat the crossover as having only two blocks.

Hi Dave
Yes that worked.First time i did it,i got confused when it ask for 4 blocks so i made up 4 blocksand of course it wouldnt let me attach one sensor to 2 (different named) blocks.
Thankyou working nicely.
