Hi Harsh,
It is always a wise move to use an active breakout board which opto isolates your input and output signals from the PC parallel port, just in case anything goes wrong - It can save the life of your PC.
I took a look at the manual but on one page it says DP4 should be ON for step and direction pulse input and on another page it says it should be OFF for step and direction pulse input. The whole document is quite confusing so I understand your problem.
However, I think this controller will work OK with Mach and as soon as I get time I will draw a connection diagram of how I would connect this up.
