  1. If you have multiple networks, never answer yes to this dialog for any com port other than the one assigned to your regular network. And honestly, not even then. It is a shortcut allowing those with only a regular network to set the network configuration of the regular network without going into the network configuration. But it is a trap for users with multiple networks. If your regular network is com3, and auxA is com6, and you use the HWU to test something on com6, and answer yes, you will now have a network configuration with regular network on com6, and no com port for AuxA, and nothing working, as your regular network data is now going out the com port for AuxA. With multiple networks, only allow the network configuration tool to update network configurations, and things will be simpler.
  2. The firmware will usually shut off lights if no commands for a long time. The show player should send commands updating periodically. You could try changing long on commands to one min of full on cycling with 1 second of 99%. Or if you have a mix of commands, and things freeze, it could be a com issue. The RS-485 chip may be marginal, or cable issues occasionally only affect 1 controller, depending on how the reflections line up.
  3. Moisture can take a controller off line. But a LOR reset retains the controller ID.
  4. This is neither TIA 568A, nor B, and results in the differential signaling not riding on a twisted pair. 4&5 are the data pair. Wired this way, 4 is twisted with 3, and 5 is twisted with 6, when 4 is supposed to be twisted with 5.
  5. DirectX is video. It is bundled with S3, and the installer runs every time you update LOR. It does still sound like a codec issue somewhere.
  6. No reason not to use a hub. Several 56Kbps data streams can easily fit in a USB 1.1 1.5Mbps connection, and that is the slow USB mode.
  7. I keep a spare mini tree pre wrapped with 20 strings of CDI equivalent LED. (Yes, they can be used as flood lights) and have the 32 strings on hand for a spare belagio pole, just have not wrapped it yet. Same for a spare half arch. And this time around, I ordered 2 spare wall washers when we replaced the ones we have used the last 7 years. I still have a spare iDMX, since we still use one. For your case, spare cords and network cables seem to be the first thing after a backup copy of all files. Then maybe find someone with a spare FM transmitter who will also allow you to have sparing rights to their spare? Or eventually upgrade to an EDM, and keep the current one as spare.
  8. I'm thinking it is more likely an issue with the mp3 and WMP. I would have suggested simply opening the audio in audacity and exporting to a new name. Rename the old audio file, so that you get a file not found error on the audio when you open the sequence, then point it to the new version.
  9. Not entirely sure where the disconnect is. It usually really is that easy. We currently run 5 networks of LOR and 16 universes of e1.31, and other than having the "is this the network to use for shows" question in the HWU mess up network configurations, it always has worked as expected.
  10. I'm not sure what would prevent control panel from showing in your start menu other than a bad install.
  11. Should be control panel. If you open sequence editor it shows a level other than demo?

    I agree it sounds like you should focus on cables and connectors around the transition from no issues to some issues. Also move your data cables further from noise sources like power if possible.
  13. Glad you found it. This is something I occasionally do when I don't realize that the cable I cut in half and put new ends on was wired 568A. I never do A unless matching existing, or required, and hardly ever run into a cable built as A, so I never think to check first. I need to check that the batteries in my tester are still good. I think it has been a few months since I used mine.
  14. For clarity, most patch cords are not crossover cables. Excluding lab configurations, fewer than 1 in 20 cables will be crossover. Computer to switch is designed to be straight thru in Ethernet. Crossover is only used in computer to computer, and switch to switch configurations, and is becoming less common with gigabit and auto-x interfaces. But, ironically, a cable with TIA 568B at one end, and TIA 568A for the other does actually make a functional Ethernet crossover cable. But not by design. 568A is how telco types would assign colors to pairs, and 568B is how computer types did it.
  15. But I thought in response to me talking about RMS of rectified sine waves a few days ago that you said that using RMS for dc waveforms was incorrect, and that only average applied for DC waveforms?
  16. And going back to RMS, and the importance of terminology, even on positive only waveforms, there is usually a difference between RMS and average value. Take a sawtooth waveform, 220V at peak, declining to zero, and immediately repeating. This has an average voltage of 110V. But it has an RMS voltage of 126 V RMS If I place this across a 126 ohm resistor, do I get 1A of current, or do I get 0.873 A? Am I dissipating 126 W, or 96.03W? Or are you doing more adjustments to finally get back to 126W, or do you think it is some other level of power dissipated?
  17. I wonder if there is also benefit to turning off hyper threading? After all, if the processes occupying a hyper thread core pair are not designed to sync up and work together, they are basically just sharing one CPU core.
  18. Actually, what value is useful will depend heavily on what you are trying to do with it. I suppose average voltage of pulsing DC might be a decent representation of expected motor speed. If it is square wave, it should still be a good representation of power which will heat a resistor or light bulb. But if power into a linear load is what you are interested in, and the waveform is not square, RMS is still relevant. But even with a square wave, if you have a non linear load, average is only useful if it is known relative to peak, and I would rather have it as peak and duty cycle personally. At some level, this will tie back to how the meter is expected to behave, so you have some idea what its readings are really telling you, given the system you are trying to validate.
  19. One location has a 2 inch conduit through the concrete block and brick, glued to a 6x6 plastic box with a gasket sealed lid. Inside, there is a 6x6 maintenance pannel, which exposes the end of the conduit as it exits the insulation in the firred out thickness between the block and drywall. So far, I have just stuffed some foam in the conduit, and taped a bag over the box when we have cables running through it. Much less water intrusion than when we were running multiple cat5 and RF coax under the window. At home, went through walls into the garage, then under the garage door, and around the house.
  20. To add more confusion to the mess, presuming a linear load, which is sort of implicit in the context of RMS, a string of incandescent lights will behave the same on just the positive (or negative) half cycles of a 120VRMS (clipped sinusoidal) source as on a full sinusoidal 60VRMS source. They will both light up at the same brightness. Though the one on the alternating half cycles will fail somewhat faster, and too much load will cause more heat in the supply transformer. But, you replace that linear load with a non linear one, and RMS voltage no longer tells you how the system behaves. You plug a typical string of CDI LEDs into the first source, and you get 50% brightness. Plug it into the second one, and the cumulative voltage to meet the current knee for the LED string may not exist at peak voltage, possibly yielding only 2% intensity.
  21. I've forgotten where this even started. But I'm not sure where 120V comes from in relation to peak voltage. Isn't the peak voltage in a 120RMS waveform something like 170 volts?
  22. I've actually never seen a flicker from too few. I have about 80 channels with one string of C6 70 count LED, and never have seen any issues with them.
  23. You listed hold on current as part of the issue. The current drawn never goes down as the number of strings goes up. Plus, I don't think I have ever seen a string flicker lower than what the output would be with some linear load. Only brighter. With a string or two, the output voltage for 100% on tracks line waveform beautifully. Current looks much like you sliced the middle third out of the waveform. A nice curved positive peak, a flat line, then a nice curved negative peak. And phase angle dimming looks just like you would expect. The leading edges of these waveforms get trimmed off. When you add more strings, at about 2/3 of the way through the half cycle, you start seeing a deviance. The voltage starts to have an inflection point and a straight line (slow discharge) that does not reach zero by the next half cycle. Current does not change behavior, just the voltage, because you now have more capacitance than the LED strings can drain once below their voltage knee. It appears to be this stray voltage on the load side of the junction that is causing it to retrigger right after zero crossing, even if the phase angle dimming is not calling for it to be triggered. The non linear dimming? Remember the current curve being flat line near the ends of the half cycle? That is throwing off the trigger delay to brightness curve.
  24. In my experience, the flicker I have seen is between the correct intensity, and full on. So it is the same effect, just not taken far enough to be reliably all on. The question I have never figured out exactly is that the triacs don't switch off at zero voltage, but rather zero current. And, even if the current half cycle SCR were to stay on past zero crossing, how is it triggering the opposite SCR, for the next half cycle? Is charge leaking back into the conducting SCR, to the shared gate, and this leakage triggering the other half? I'm not really sure if that is the exact mechanism, or some other characteristic that I have not yet read about, but it is my best guess to date.
  25. How about the idea that an opto triac can dim in proportion to voltage? The key spec that allows dimming is that the opto triac can be fired at any phase angle, not just zero and 180. Most opto triacs only switch on at zero crossings, and are only suitable for on/off control. The input is still digital, LED on, or LED off for either version. But with non zero crossing versions, the micro controller can detect the zero crossings, and after a suitable delay trigger the opto, which will trigger the main triac. Then it turns off the signal, knowing that the triac can't turn off until current goes to zero again. So the less delay, the more on time, and the brighter it is, the longer the delay is, the less on time and brightness you get.
