morte615 Posted March 28, 2011 Share Posted March 28, 2011 Hey all, I just built my first board (CTB16PC)and am trying to test the board out. First of all I don't have the USB to Serial adapter (or for that matter haven't paid for the software yet, waiting on tax check first) so can't connect it to the computer to test. I first powered on the board and the LED started to blink, then stopped. Now whenever I power up the board the LED does not light at all. I did the trouble shooting in the guide and everything works like it should.What I am wondering is there a way to check the board more in depth without connecting it to a computer? I just want to know if the board is working so that I can go ahead and install it in the box!Thanks everyone! Link to comment Share on other sites More sharing options...
LightORamaDan Posted March 28, 2011 Share Posted March 28, 2011 If the LED is not blinking I would not put it in a box. It will be difficult to test it further.Try removing the 8 pin comm chip from it's socket to see if the LED will start blinking. If that is the case then during testing you may have shorted out a couple pins and damaged the chip. No big deal if that is what happened we will just send you a new one.Dan Link to comment Share on other sites More sharing options...
morte615 Posted March 28, 2011 Author Share Posted March 28, 2011 Took out the 8 PIN chip and still nothing on the LED. If I take the chips out and short the lower left pin to the 2nd down on the right (on the 18 Pin header) then the LED lightsAlso I do get +5 volts between the gnd and the 4th pin down on the left.

LightORamaDan Posted March 28, 2011 Share Posted March 28, 2011 With all the chips in do you get the +5 volts on the meter? In general if we have 5 volts the processor will blink the LED. It did so for a while so we know the processor was good, etc...Dan Link to comment Share on other sites More sharing options...
morte615 Posted March 28, 2011 Author Share Posted March 28, 2011 Yes I get 5 Volts on the 18 pin header with all the chips in, but the LED does not light. But if I short the gnd and the 2nd down pin the LED lights so the LED itself is fine. Link to comment Share on other sites More sharing options...
LightORamaDan Posted March 29, 2011 Share Posted March 29, 2011 Try a reset on the card to see if that helps. You should have a jumper on the second row of the 18 pin header. Power off the card, remove the jumper then power on the card again. The LED should flash fast. Regardless of if the LED flashes unplug it after a couple of seconds. If it is going to blink it will blink within a second and as soon as it starts blinking the card has been reset.Dan Link to comment Share on other sites More sharing options...
bisquit476 Posted March 29, 2011 Share Posted March 29, 2011 If Dan's remedy doesn't work, you may try what worked for me on the blue board. Unplug the controller, remove the PIC chip, power on the board for a couple of seconds, remove power, reinstall the PIC, and power the board back up. I've had to do that to my build boards the last 2 years, works like a charm for me. Hope this helps,Bill Link to comment Share on other sites More sharing options...
morte615 Posted March 29, 2011 Author Share Posted March 29, 2011 No such luck on either Even without the board connected to a computer, the LED is supposed to light, correct? Link to comment Share on other sites More sharing options...
bisquit476 Posted March 29, 2011 Share Posted March 29, 2011 Maybe post some clear hi-res pictures for us to look at, after looking for so long, sometimes the eyes go buggy. Link to comment Share on other sites More sharing options...
Guest wbottomley Posted March 29, 2011 Share Posted March 29, 2011 Anyone thought the LED might be bad?I have one board the LED does not blink but still works.Just a thought. Link to comment Share on other sites More sharing options...
LightORamaDan Posted March 30, 2011 Share Posted March 30, 2011 I think this will be a tough one to find remotely. You said that the LED did blink for a while and then quit. Leave the card plugged in for 5-10 minutes then unplug it and feel around for anything that is hot on the card. I think this may be a case where it willl need to be sent in for repair.Dan Link to comment Share on other sites More sharing options...
morte615 Posted March 30, 2011 Author Share Posted March 30, 2011 @MountainwxmanThe LED works, I can get it to light up by shorting pins on the 18 pin header.@bisquit476Here are a bunch of photo's of the board, not really hi-rez (all I have is my camera phone) but pretty good anyway.https://picasaweb.google.com/morte615/LightORamaKit?feat=directlink@LightORamaDanOK I will try that today, but how do I go about sending the card in to get looked at?

morte615 Posted March 30, 2011 Author Share Posted March 30, 2011 Just had it plugged in for about an hour (I know, I know 10 min or so. But I forgot it was plugged in lol) and the only thing that was warm (and not by much, just slightly over room temp) was Q16 (See attached pic).Yes when i first finished the card, I plugged it in and the LED flashed a few times then stopped. Then when I unplugged it and plugged it back in the LED has not turned back on at all. Attached files Link to comment Share on other sites More sharing options...
Ron Amedee Posted March 30, 2011 Share Posted March 30, 2011 Just throwing this out there..The IC chip to the left of the Cat5 connector looks to have pin 1 on the left side...Most boards i repair..pin one is on the right. Could just be the picture..Plus have never built this board but have built many like it.If i'm wrong kindly disreguard !!!!!!!:shock: Link to comment Share on other sites More sharing options...
morte615 Posted March 30, 2011 Author Share Posted March 30, 2011 Yeah just double checked the instructions, that's the correct orientation.Thanks though. Link to comment Share on other sites More sharing options...

bisquit476 Posted March 30, 2011 Share Posted March 30, 2011 Did you use the troubleshooting guide? I had a board with Q16 being hot, I think it was the 485 chip that was bad. But follow the guide.

morte615 Posted March 30, 2011 Author Share Posted March 30, 2011 Yep went to the troubleshooting guide first, everything it tells me to do so far has been ok, except no LEDAnd Q16 isn't really HOT, just slightly warmer than the rest, no where near where it would be if the board was running.

Move the jumper down one set of pins and I'll bet your controller will start working just fine.If it is on the second set of jumpers, then my apologies, but from what I can make of it and blowing the photo up, it does appear the jumper is not in the correct location!

morte615 Posted March 30, 2011 Author Share Posted March 30, 2011 Nope jumper is on correctly (second set down from top) it's just a bad angle on the picture.Thanks though! Link to comment Share on other sites More sharing options...
