  1. Connecting a fan to the Pixcon16

    That's what I thought. It must have been a misprint on the Light-O-Rama's Pixcon16 stats page that the AUX OUT was using PWM. Thanks for clarifying that for me.
  2. Connecting a fan to the Pixcon16

    Hi, I read the manual, but was still confused as to why the fan always stayed on at high speed. It's a 12v fan and the board is being supplied with 12v. Part of the reason I was confused was because on the Light-O-Rama Pixcon16 page (http://www1.lightorama.com/pixcon16/) where it said "Auxiliary output allows PWM control of an external fan for automatic temperature regulation inside an enclosure." I wasn't aware that PWM could work with just 2 wires. I'm still confused as to how the Pixcon16 can do PWM with just the two wires, but I'm not even remotely experienced with that. Or maybe their description is incorrect about PWM on the Pixcon16. I have no idea. However, I did find out that I don't have the problem I thought I had. I took a meter and measured the actual volts coming out of the AUX OUT. The reason I thought the fan was always running at full speed is because the board outputs about 10.8 volts at the initial start of the fan. It then gradually increases until it reaches the full 12 volts, in about .2v increments. The difference in fan speed between 10.8v and 12v is barely noticeable, which is why I didn't notice. I had expected the fan to run much, much slower initially. But at least I now know that nothing is wrong, it's just not a big difference between initial start and full speed. Thanks again for helping me out. Bob
  3. Connecting a fan to the Pixcon16

    Thanks Ebuechner, When the fan comes on at 80 degrees it's at full speed. In fact, whenever it's on it's at full speed. Is there a special kind of fan I need to buy that will run at different speeds? Is that what PWM fans are? If so, those fans seem to always come with 4 wires, but the AUX OUT on the Pixcon16 only has 2 wires (Positive and Negative.) Bob
  4. Hello, I need some advice on hooking up a fan on the Pixcon16 Controller. I bought a small 12v computer fan and hooked it up to the Pixcon16's Aux Out connector. The fan does turn on, but not at the right temperature. The Pixcon16 is configured to "fan turns on at 100% at 95 degrees." However, the fan comes on much sooner. When the fan came on, the board was showing a temperature of somewhere around 80 degrees, which was not near 95 degrees. Also, what does it mean when it says "fan turns on at 100% at 95 degrees? Does this mean the fan doesn't always turn on with 100% power? Bob
  5. Is this wiring safe for Pixcon16?

    Thanks so much. That's exactly what I needed to know. I apologize for all the questions, but I wanted to be sure I didn't blow anything up when I turn all this on for the first time. :-)
  6. Is this wiring safe for Pixcon16?

    It sounds like there are two things going on here. If I'm reading this correctly, TheDucks suggested putting a bond wire Between a V- terminal of one power supply to a V- terminal of the other power supply. Also, Dibblerjr suggested putting a bond wire between the Ground terminal and a V- of the same power supply (and do the same to the other power supply.). My question is this: Are both of those suggestions needed or does one make the other redundant? Bob
  7. Is this wiring safe for Pixcon16?

    OK..... This may be totally stupid, so forgive my ignorance. What I had planned to do was to buy a small 2-foot 12-gauge 3-pronged extension cable. I was going to cut off the female end and connect those wires to the input terminals on Power Supply #1. Then I was going to connect those exact same terminals on Power Supply #1 to the input terminals on Power Supply #2. Then connect those same input terminals on Power Supply #2 to the input terminals to Power Supply #3...... then do the same thing from #3 to #4. Does that work fine or is there something in your head screaming "This guy is insane." Oh, the male end of the 2-foot 12-gauge 3-pronged extension cable would plug into a 12gauge extension cord from the 20A receptacle.
  8. Is this wiring safe for Pixcon16?

    In the picture I uploaded, aren't the grounds already bonded together? All the grounds are connected together. Is that what you mean?
  9. Is this wiring safe for Pixcon16?

    I do have a few 20A circuits available. We had a subpanel put in awhile back. Most of the breakers are 15A. However, there are three 20A circuit breakers in the subpanel, each going to 20A receptacles using 12g wire. If I use a 12g extension cord from one of those receptacles to the 4 power supplies, will that be sufficient?
  10. Is this wiring safe for Pixcon16?

    I knew that would drive you crazy. 😁
  11. Is this wiring safe for Pixcon16?

    They are 360W power supplies, which I think comes to 3A each on 120V. So that would make it 12A for all 4. Is that too close for a 15A circuit? I'm not sure what you mean by "bond wire." Sorry, I'm really new to this. Do you mean connect a wire to a negative terminal on one power supply to a negative terminal on the other power supply (the two power supplies feeding one Pixcon16?)
  12. Hello, I'm not exactly great with electrical wiring. Can someone look at the attached photo and tell me if this is safe? I'm wiring two Pixcon16 boards with four 12V Power Supplies. I randomly chose colors for the picture, so ignore the incorrect coloring. My main question is whether or not I can daisy chain all the power supplies together like the picture shows even though they are going to two different Pixcon16 boards. Will that affect the Pixcon16 normal operation in any way? Are the two Pixcon16 boards separated properly? Thanks for your help Bob
  13. Multiple Pixcon16 boards setup

    Thanks TheDucks. That makes a lot of sense. That way the new cold air will run across the equipment. Thanks!!
  14. Multiple Pixcon16 boards setup

    Thanks for the link to the vent cover. In the video I couldn't see the actual vent. But now that I see it on the link, I can see why you had no problems. I didn't realize it had a cover pointing downwards. I'm buying some of those!!! Thanks again!!
  15. Pixcon16 Gigabit Speed??

    Oh no.... I absolutely do not want to return them. I didn't really care if they were Gigabit or 10/100. I just wanted to be sure I was hooking it up for whatever maximum speed it ran at. Thanks so much for everything.
