pastorbobnlnh what was your experience with the r600?
I doubt this is the problem. Double check that the L limiting screw isn't restricting the RD's lateral travel by moving the RD by hand with the cable disconnected or very loose. Or you may not have had the shifter in top gear during installation. Put the rear in top and try to upshift one more time, no indexing should be felt and the cable shouldn't become looser along the down tube.
One more possibility is that the jockey pulley is hitting the bottom sprocket and the B screw needs adjusting.

PS I'm guessing it won't shift to the largest cassette sprocket while on the smaller chain ring. If it's a problem on the big chain ring, the chain could be too short.
