Hi Jay,
The steps is the manual should work. I have read the manual you are using. I presume the step you are talking about is step 6. That step is broken into two parts, 1 part for the DAQmx driver and one part for the Trad DAQ driver. You should only carry out one of these steps. I recommend using the DAQmx driver.
As for your 2nd question, you can send and receive handshaking and triggers through the backplane. See the following links for more information.
