Got a pair of new chips on they way.

Thanks for the offer Freddy,
I'm working with another member presently about just the chip so I don't think I need to take you up unless it falls through but thank you anyway for being generous enough to offer. If something changes I'll get back with you.

Add me to list for 2, please.Sorry scratch that

"1750 GM5 chips have been sold, I don't believe that nobody could give you a spare part! ;) Best Regards, Thorsten."
I can't believe it either!
-
Group,
If anyone has a spare chip to sell please contact me via PM.
Want to buy a single GMx5x5 chip. Ships to USA.

Thanks for your response Thorsten,
Sorry for being vague,
I know the main power LED is good. I proved it out of circuit. All RCV LEDs are constantly lit. Nothing blinks, no comms, no recognition of GMx5x5 in Windows 7 or Windows XP device managers.
I'm doing hard node by node this week to see if I have a bad trace somewhere, but the board looks really clean, I still think it's the main chip. Will post results as found.
Best regards.

Group,
Thanks for reading this.
Is there a troubleshooting thread, if so please re-diriect aka bump, I've noticed many bits and pieces here and there but wonder if I'm overlooking the obvious.
In building my second GMx5x5, I cannot get the main LED to light, however all others do. It seems there may be a short somewhere on the main lines but tracing continuity doesn't concur. Caps are properly polarized as are diodes. Hex converters and iso opts are proven tested in first unit, which works perfectly. I'm concerned I may have a bad main chip. This is a rev 1.12 board. Suggestions are welcome.
I also notice a chip replacement order up but very slowly filling. If anyone has a spare chip for sale I might be interested.
Best regards,
Jon Pyre, Orbitalgun.

Woohoo, got my boards! Thanks so much for working with me, now I need to get sourcing parts...
-
Yeah, that's more than fair. :thumbsup:
How much is insured shipping? :unsure:
It wouldn't have to be a rush to arrive so long as I knew they were insured. (BTW, Do you mean replace the entire order?) :yes:
-
Lame, my post office received my package without the pcb's inside and not insured. :no: Looks like the envelope was torn in transport. :unsure: Shipping during Christmas, who knows.
Good grief, Jerome, I know your boards are hot hot hot, but really, someone stole my mail to get them? :angry:
Let this be a lesson to any one ever contemplating not insuring your stuff....
There's 35 bucks down the drain. :sad:

It seems like so long ago that I read this, I forgot it. GM5x5x5 is now working all ports in and outs! Thanks for the response DIgi!
-
Settings for number of active ports is on the board, does the white dot represent jumpered?
What is J8 for?
Does the main led need to be populated to make the device work?
-
Got mine too! Thanks for the hard work.
-
Any possibility of getting on this order for 2 boards?
-
I got a few spare GM5 ICs (straight from ploytec) that I'm willing trade for a GM5x5 PCB. Let me know if you're interested.
Very interested I was turned away for no more GM5 chips today via email so I can get your board if your still available to trade...
time sensetive please respond asap.

That was it, I replaced the main chip and even tore a pad but was able to get the unit up by soldering the lead to the conjoining via. Thx to everyone who helped make this work out for me. I'm stoked! Now I have the excuse to possible mount both these in a single rack.
