Distance between the SSC and the first pixel

[travailen]

I'm laying out my show and can see some advantages to having some SSC's a little distance from the first pixel. I would like to run the cable between the SSC and the first pixel about 10 feet. Has anybody had any experience with this spacing. Also, are there any guidelines regarding the SSC pixel spacing?

Thanks,

Rick S

The question comes up often, but I never write down the answer or mark the thread.
I think it would be a great service to record a summary of the cable lengths.

I'd like to see pixelnet lengths,
DMX lengths,
SSC (to first pixel) lengths,
max length between pixels,

...and I'd even like to see the impact of wire gauge on amps for the 110v wiring.

Putting this info in the wiki would be great.

Keep the distance short to the first pixel or you will have problems. There is another thread about it but I can't look it up easily on my phone. Initially the title mentioned a possible bug which later turned out to be something else causing the problem. In the thread RJ mentions changing a resistor to get more distance to the first node. With the original resistor I wouldn't go beyond 2 feet. The symptoms are the first node will be a different color than the rest. And the rest will often be the wrong color.

I believe this contains what your asking about the SSC's

There is an issue that one of our members (Corey) pointed out to me that is causing this. I have been testing a firmware update that seems to make it solid and should make the 6 ft I have always used as a max length not a problem agian.  There is too many variables to use 10ft as a promise. You may do this all day no problem. But I can't promise it as it is getting long for the type of comminucations were talking about.

Most people are telling me it is not creating a problem on the normal length of lead on the strings they come with. But longer can cause this issue on the current firmware/hardware setup.

Is there a guesstimate on when the new SSC firmware will be released and will that be posted on the wiki and a thread noted about it in the forum to let everyone know to update their SSC's?

Thanks again for all your hard work RJ

yes, once it has been tested well.
It is a few weeks away yet.

Should we hold off on replacing the resistor then? Or is it a combo new firware and resistor replacement?

Good question- forgot to ask that one!  Thanks

I would hold off on making any changes until the changes have been approved and released.

[RJ]

I would not mod anything yet.

Perfect- thanks

Okie dokey my replacement resistors are still in a bag. Now back to sequencing for me! Well after work that is.

Ok another question!  My length between the controller and the first nodes are less than two feet, I have cut my flex strips in half, I soldered the halves to more wire, programmed all my strips.  Tested then, but myself and another DLY member have had the same experience.  On one of the cut halves which is the back half, it appears that the last 3 nodes are not working.  I am having this issue with two strips.  All nodes were working fine before I cut them.  The other three halves are working fine as well.  I have programmed them twice over, rechecking their numbers, still to no avail.  I was testing them with all strips on using color finder, also using test sequences in vixen from nutcracker to test.  I have switched those two strips to two other ssc's and the last three nodes still don't come on.  I've checked the soldering, there doesn't appear to be any bridging that I can see.  But if they were working before the cut and not after the cut, any ideas for more troubleshooting??  I am at a brick wall now!

Thanks
Julie

Would this be an instance where I would need to change the resistor to 150 ohm on the SSC?  Even if it's for a flex strip and not a string?  To help those last 3 nodes speak so to say?
