Hi folks,

One of my next steps is to get polarity reversal working on the Heinzinger supplies.  I've got the attached bob file where I am hoping to use the slider to tune the beam. The PCUs want me to send a negative value to indicate one polarity and a positive value to indicate the opposite polarity.  The command 'DA 0,025000' will run the supply to 25A.  The command 'DA 0,-025000' will reverse the polarity switch and run the supply to 25A (the software on the supply takes care of running everything down before switching).  I would prefer not to have a slider that goes from -300 to 300.  This makes it harder to run the supply down to 0 and is also more confusing for operators.  My thought is to implement a toggle button and display which deflection the user has selected.  I think I can then add a CALC record to set the sign of the number as positive or negative, and then send that composite out to the instrument.  Does it sound like I'm on the right track or feedback on how you've accomplished something like this?  
     Greg
