Steve. Your CTL switch must be connected to an a RSL CARD INPUT.

When the key switch is turned on, it will give the signal to the RSL.

Check the address on the RSL seeing which links are on on which are off. The binary code will be 1 2 4 8 16.So seeing which pins are on you can come to know the address on the RSL.

Then this address and the input pin number you set for the address 1290 on the controller. For example

If links 123 are on, in the RSL, then the address will be 7. And if you have used input number 1 to connect the CTL switch to the then the address is 07/1. So input this on 1290.

Hope this helps. I stopped working since 2008, so my apologies for the incorrect info in my previous post which was corrected by another member. All the best.
