Here is my problem. using a laptop with Vista(Not my choice a hand me down)I have a heart beat on the ren c with power on ren c and 595. I only have first 8 channels with 595 chip and I have changed them as well. when I start the sequence the rx d7 led lights up but the first 8 channels stay on. The sequence starts out with all channels off. Please Help. I must be over looking something.
