Question about HB-25

Just a quick programming question. Is there a problem with using HIGH/LOW commands when codeing the HB-25 rather than using PULSOUT? I just want to be sure that these commnds are acceptable with the HB-25.
Edit: Although I already have 2 HB-25's that are new, I could not resist watching a brand new one on EBay. Ended up winning it for $33.00 shipped. Not a bad deal considering they are $50.00 plus shipping.
