Pete, I know that. The cab 1 and Cab 2 can both be used to reprogram the R2LC boards. Jim I see that often. Whenever I get an older TMCC that has not been run for a while, the first thing I do is reprogram the R2LC and move on down the line. Many times doing the R2LC can put you right back in the ballpark and that ends the problem. As mentioned earlier, I am starting to see more of the R2LC boards failing. Like many other boards, they are getting old.
