    Are you measuring FCC when no multimeter and also multimeter when no Fusion Brain connected at all?

    Multiple measuring devices will make the readings false on both ends.

    Yes, the measurment point was unplugged from the brain when the multimeter readings were taken, and vice versa. I really wasn't expecting the brain to be higher, but I tested it several times.

    That is odd. Is it just a plain old potentiometer? No pulsing or such going on with it?

    Is this on all the Brains you have?

    Yeah just a linear pot.

    I could switch them around and see (though it will be a pain if you look at the setup in the pics above), but this is on the new one I just recieved. I'll try the other one tomorrow. I can just switch the paths for the brains and swap all of the connections, so it won't be that hard.

    I know from past testing that the 4.86V is definately correct, as opposed to the 5.0V I'm seeing on both the virtual brain and my labels (direct reading from inputs).

    I'll let you know tomorrow if I find anything else with that.

    (The other brain hangs up, so it's no use for this test).

    The only thing I can think of is that I'm not using signal ground. All components are common at the power supply only, and the HVAC head, the interface board, and the 2 brains all have their own 5V supply, from that common 12V supply. I didn't think it would make a difference, but maybe. I don't know, I just metered between the two grounds and the difference is zero.

    Well if the difference between the grounds was not 0, then that would be the problem. But since it is the same potential, I dont see the lack of grounding to the Brain as a problem.

    There was a problem with the accuracy of the analog inputs that was improved, and hopefully fixed, and few months ago. The brain we just shipped you has this fix implemented, for sure... did you recieve it yet? The brain also has a pretty low input impedance... whatever you're feeding it with needs to have an impedance of 5kohms or less.

    This is using the brand new brain that I just recieved. My first one with color coded inputs, I might add. It really brightens the room, I must say

    Seriously though, I measured resistance looking back through the circuit to ground and for these three pot circuits that I was referring to, it measures highest when the pot is halfway, which is 2.5K to ground and about 5K at maximum to either the control head's +5V rail or the brain's. Here's a schematic of the circuit, it does have resistance that is higher than 5K (20-9.5K pot, 30K to +5, 10K current limiter) but when measuring J10 at the parallel paths must work it out to be as low as I measured...



    And this isn't the only thing that's off. Everything is a little off. For this, with most, it doesn't matter, as long as it is consistant. But it would be nice if it were more exact.

    It's been a while sense I was busy with the modernity skin for this, and I just haven't played with the software as much as I would have liked to in the past months. I know with the Root function loops, I once asked for the ability to rename them in the configurator, I still think that would be nice, to keep track of them. I also find myself wanting an 'else' statement.

    In the case of the outputs tp the DAC, the best way I can think of is to map out each variables state for each number, so that say for the MSB, it will be a 1 if X >= 9. And for the LSB, it will be a 1 if X = 1-3,6-8,14,25 or 26.

    An else would be helpful in specifying that each bit should be 0 for the opposite. As it stands I need another loop to do that. So, for 6 bits, that's 12 loops, not too bad, I suppose. But then there's the if X<=0, x=0 and If X>=26, x=26 loops. It starts to add up. And this is still the basics.

    I'm going to try to see if I can localize this a little more by using the simple pot that came with my original brain, and see if it measures right, both with the multi-meter and the software.

    but for now I have a software issue!

    It must have occured with the update somehow, I had this working just fine right before, and I haven't changed anything:

    See the end of this message for details on invoking
    just-in-time (JIT) debugging instead of this dialog box.

    ************** JIT Debugging **************
    To enable just-in-time (JIT) debugging, the .config file for this
    application or computer (machine.config) must have the
    jitDebugging value set in the system.windows.forms section.
    The application must also be compiled with debugging
    enabled.

    For example:

    <configuration>
    <system.windows.forms jitDebugging="true" />
    </configuration>

    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the computer
    rather than be handled by this dialog box.

    Then I got the, "Uh Oh, you shouldn't be seeing this " error. (Not responding)

    Time to check my stuff...
