My Ocelot has been very robust for prolly 9 years, till today.

The Comms LED and one of the other LED's (I can't recall which side of the coms light it was on) were flashing alternatively very rapidly. I cycled the power and now I have a solid comms LED up.

I'm going to need some help to t/s this.
it won't recognize or indicate response to IR, and just sits there.

Ny thoughts?

Ben

Is the Active LED blinking on the Ocelot? If so how many flashes does it do? 1,3,4?

Active light does not light at all

the comms light will eventually flash without any rhythm after a startup/power cycle, but no other indication at all.

I haven't tried to connect to it, so I can't confirm the status of the executive or if is even there.

I did another power cycle, uplugged my PSC-05 and waited for a restart - afterwards, the LED's are again performing differently.

Ocelot:
Active - steady dark (nothing)
Comms - flashes on when X10/IR LED is dark
X10/IR - blinks about once per second (and does seem to recognize IR commands)

If Active is not blinking at all, then the cpu is not doing anything and the Ocelot is essentially dead. Send an email to adiinfo@appdig.com and ask about what repair options are available.

I sent my Ocelot to Applied Digital between Christmas and New Years, with an e-mail indicating the description of the problems.
Tracking Data showed it's shipment progress, and it's delivery.
Kevin confirmed it's delivery, and said they would get to it right away.
I had sent a couple e-mails to them since, to confirm completion and arrange payment for services - but I kept getting conflicting delivery receipts for the e-mails, so today I phoned and asked of it's progress. Mr Jones in tech support indicated it was complete, and confirmed the return mailing address. Kevin then replied that the Ocelot had already been shipped back to me a couple days prior...

Literally within minutes, one of our in-office admin reps called to say there was a fed-ex parcel that had come in - it was my Ocelot!

I brought it home, plugged all peripherals in, and plugged in the power supply. I still have a solid "comms" light up. Nothing appears to have been repaired.??.
Further investigation revealed that it's not my original Ocelot, as the IR receiver is of a different design and is a slightly different orientation (my original one was slightly askew and had a transistor shape - this one stands bolt upright and is cylindrical

I'd have taken this up with Applied Digital personally again, but as it's off normal business hours I thought I may get some more input from them here on the forum instead.

Anyone?

[Peaks around corner to see if anyone is here/]

I thought I was being patient enough, I even let the Ocelot sit for at least ten minutes with the comms LED lit up.
After ten minutes, I looked at it and the IR/X-10 LED and the Comms LED started toggling off/on in alternating sequence, still no "Active" LED doing anything...

I unplugged the PSC-05, without powering down the Ocelot and I saw the IR/X-10 LED go out, but then the comms LED stopped blinking and the Active LED flashed three times
I recalled that being the sequence for the processor starting up.
After a few cycles of three flashes, it switched to four flashes (...Processor is running it's program....)
I plugged the PSC-05 RJ-11 plug back in, the IR/X-10 LED lit up green like it was supposed to, and teh Active LED continued to cycle with four flashes - I checked with an IR remote, and the IR/X-10 LED would switch to yellow upon receipt of the IR signal.

I guess all is resolved - I'll use Guy's retrieval utility to take a look at the program that was previously installed and see if it remotely compares to the original I had on mine - I suspect there will be no more issues, other than possibly loading my original file.


My appologies for apparently jumping the gun and being critical.
I'll update this thread when I have new info,

You don't mention if you have expansion modules or how many. You should take a look at the Ocelot's parameter 3 and set it to match the highest module address that you have (and set it to 0 if don't have any) for the best startup delay, since it scans for modules when powering up.

If ADI actually sent you another Ocelot, then it would not have your original program in it... You should proceed by reloading the executive, then your program to make sure that everything matches up. You might also need to restore any IR codes and ASCII strings if you used those too.

There are no expansion modles in my set-up.

I was unaware of parameter 3 being the one that determines the amount of time the Ocelot takes to locate and address connected modules. I'll certainly make a note of such.

Regarding the program contained within the this Ocelot, my USB-Serial interface is at the office in my laptop bag at the moment, so I won't be able to attach and access the Ocelot till tomorrow at the earliest, but I don't want to purposely delete someone else's program (if indeed I have a replacement Ocelot.)
I think I'll wait till Kevin chimes in on this thread prior to overwriting the existing program - just in case it's a client's
huge 1500 line program with possibly no back-up.

Prior to shipping it in, I had affixed one label to the cover of my Ocelot with pertinent contact info, and a sexond similar label to the Ocelt's case. The Ocelot that I received today only has the label on the cover...

I opened up the case, Measured with a Fluke 87 (Calibrated yearly).
13.57 volts AC at the supply input terminals.
4.78 volts AC ( and 11.42vDC) across the 1000uF Cap (this Cap is warm to the touch - not hot) There are tiny solder marks on one of the pads where this cap is attached to the board.

The heat sink on the component (I'm going to assume the regulator) beside the 1000uF cap is quite warm - enough so that I can only hold a finger up to it for a second or so.
I can hear it buzzing when I hold it close to my ear.
I can't get an accurate surface temp reading off it, as the FLIR infrared camera I use at work is not available.

The open circuit power supply voltage is 14.07 volts.

Measure the voltage across the regulator output in dc volts. This is between the center and rightmost pin (the "front" being the side facing the center of the board. This should measure very close to 5.00 vdc.

Ugh, that's not good.

Something is drawing too much current. If you want to try and troubleshoot this you could start by trying to remove some socketed chips (always with the power off) and measuring that voltage to see if it goes to 5.00 volts. You could start with the comms chip (the 8 pin chip near the RJ11 connector) and the serial chip (16 pin chip nearest to the serial connector). If that fixes the voltage, try reinserting the serial chip and test again, etc.

Although it is socketed, don't try to remove the main cpu (large square chip), the socket is too easy to break.

That might explain my heat buildup as well.

I have to recan't my statement regarding the fact that this may not be my original Ocelot - based on how easily the board came out or the case.

Can I pull these chips out with the Ocelot still energized?

Oh crap - I just read (" (always with the power off) ").

I'll do that - I haven't pulled any chips out yet.
am I looking for the chip that causes the regulator output to return to something closer to 5 vdc?

comm chip removal gives 4.73 vdc

Yes, the idea is to see if one of them is drawing so much power that it would pull down the voltage.
