Hi, I'm having some problems understanding how to deploy singleIO method in LJPython to drive the MIO0 digital output. It doesn't help I'm coming back to this stuff after work in other areas, so I'm kinda rusty at the coding part as well. I have MIO connected to an SSR which operates a heater. In order to turn the heater off, I need to set MIO0 to "Input" mode. In order to turn the heater on, I need to set the MIO0 mode to "Output-Low". My challenge is looking at how to set this last state: "Output-Low". What combination of singleIO parameters must I use? I've reviewed sec 5.3.4 of the manual, and also the ue9 module help file, but can't connect the dots on how to set this state.... Thanks, Dean

The call would look something like this:
myUe9.singleIO(IOType = 1, Channel = 20, Dir = 1, State = 0)
IOType = 1 is Digital Bit Write, Channel = 20 is MIO0 (a channel numbers/bits table can be found here: http://labjack.com/s...users-guide/2.9), Dir = 1 is output (0 is input) and State = 0 is low (1 is high).

The example in the single IO source code (docstrings) almost did what you wanted. It needed the second parameter changed to 20 for the MIO0 channel.
