I added a second TIU to by layout today. When the power is turned the 1st one blinks once, the second one blinks 3 times. They both are powered by Lionel 180 bricks. When a engine crosses from one to the other it stops and I have to turn power off and then back on to have voltage to the tracks. Everything was working great until the TIU's were upgraded to 6.0. I've have been reading The DCS Companion on how to change the TIU id numbers and whatever I do it the second TIU always blinks 3 times. It does not state if power should be on or off when trying to change the TIU number. I must be missing something. The bricks are working fine, they feed into fixed 1 and 2 on both TIU's. Any help would be great.
Thanks,
David
