  It looks like it uses serout and serin. What have you tried that didn't work? (By the way, thanks for posting that SCP1000 code for the propeller. It got me on the right track to get mine working.)

  I'm not sure what it is just yet but I've tried many things..·
  Started with some demo code for other micros from http://www.solutions-cubed.com/solutions%20cubed/MMB2003.htm
  I'm using the full duplex serial at 2400baud..·
  This doc shows what looks like everything I'd need to get it to go, but I must be reaching some mental block...
  http://www.parallax.com/dl/docs/prod/datast/MotorMindB.pdf
  Here's a snip of my current code...· I get nothing, no blink on the modules led's, no return response from the module, nothing.·
  

      ser.start(8, 9, 0, 2_400)
  
      
      ser.hex($55,2)
      ser.hex($03,2)
      waitcnt (cnt+500_000)
      ser.hex($55,2)
      ser.hex($83,2)
      ser.hex($DD,2)
      
  
  

  
  I've tried setting the mode with non inverted..· as well as quite a number of other combinations..
  I'm wondering if the module's serial in is being triggered by the props 3v signal since it's a 5v device...·
  
  (btw- Your welcome on the scp code.. that was a bit of work.. glad it helped out, it's a great little sensor!· I saw your code and haven't had a chance to try it yet, but look forward to it!)

  I think you want to use .rx and .tx instead of .hex . rx and tx send bytes where it looks like hex converts a hex number and sends ascii.

  I'll give that a try.. I also tried decimal and strings, guess it didn't occur to me
  Thanks!

  Works great now!
