Have I killed my 2496 i/o Box??
Have I killed my 2496 i/o Box??
I know there isn't much hope, but then again, it's worth a shot .
I plugged in my Luna Box's (?) z-link cable the wrong way around, which I realized just when I thought "I shouldn't need to apply that much force ..." And it looks like I damaged something (I know z-link carries power ). I tried 3 cables and 3 Luna cards, it's basically the same: when plugging in all the LEDs in the box flash red for a second and that's it. In Scope the "connected" indicator keeps flashing rather quickly and irregularly. Any thoughts - please?!?!
Btw, I was in the process of changing my DAW from ACPI into "Standard PC" when this happened - could there be any connection?
Any ideas will be much appreciated - I love this little box .

Re: Have I killed my 2496 i/o Box??
i would think there are fuses that blow for this situation inside the box
how did you manage to plug a fire wire cable the wrong way its flat one side and hexagon the other side

Re: Have I killed my 2496 i/o Box??
I would think there's a fuse but I can't identify it.
And yes, the plug is more or less foolproof, but then it's only thin sheet metal, and with a little determination, while working with one hand on the back of your pc, not seeing anything, it's quite possible (QED) ....

Re: Have I killed my 2496 i/o Box??
fuses are some times look like an smd ic with just 2 legs but are infact fuses
i replace these with resettable fuses that go open circuit when there is a short
then reset them selves once cooled down
i dont have your model of i/o box

That's a pity, you seem to know your way around with a soldering rod. Anyway, thanks for the smd fuse tip, I'll have a look at these.jhulk wrote: i dont have your model of i/o box

Re: Have I killed my 2496 i/o Box??
open it up and take pictures for me close ups i can tell by looking at pcbs
if they have fuses and what types
as i work on component level and diagnostics and pcb design and circuit design
its my day job repairing synths samplers amp mixers outboard gear
and making specials for customers and designing and making upgrades for old tech to bring them closer to new tech

Thanks a lot for your help. I've attached a picture of the components next to the fw port - would the encircled thingys be fuses?

Re: Have I killed my 2496 i/o Box??
no there ferrite beads
theirs one right by the side of it not the back of it

Re: Have I killed my 2496 i/o Box??
the lm317 is a power regulator
Re: Have I killed my 2496 i/o Box??
its a linear ldo it has voltage in and then a regulated voltage out
check the positive led and trace back to the connector there should be a inline fuse smaller than those ferrite beads

Re: Have I killed my 2496 i/o Box??
once you trace that leg if you find a inline fuse use a continuity tester available on all small ac/dc digital meters it has a bell if its blown you wont get the bell sound if its ok you will
Re: Have I killed my 2496 i/o Box??
Jhulk, I'm afraid this is beyond me ... I'll post two more pics, maybe you can point me towards something fusey. I can solder and desolder components, but that's it.
Btw, I noticed the whole section in the pics gets warm when plugged in, even though nothing else happens.
Has noone else ever had the "connected" light flashing in the Samplerate window?

Hi, Martin
if you can't get it fixed, I have a used one but near new that might interest you,
regards,
Didier

Re: Have I killed my 2496 i/o Box??
Didier,
thanks for the offer - how much are you looking for?
At the moment I'm waiting for the parts to make an stdm-cable for four cards which would give me 4 analog I/Os (if it works ...) so I'm not sure if I'll need a new box right now. I'll let you know.

Re: Have I killed my 2496 i/o Box??
ok, let me know and we'll discuss the offer..
Re: Have I killed my 2496 i/o Box??
Sigh! I believe it's finally happened to me as well. All the lights went out last night. I unplugged Z-Link cable, re-plugged. No lights. Went through the drills. Restarted Scope, rebooted, changed cables. The "best" I got was all the lights flashed red when I plugged in the cable. Then blank. Changed cables, same deal. Well it faithfully served me for over 15 years. I suppose eventually I'll replace it but most of the outboard hardware it handled has been sold over the years for software.

Re: Have I killed my 2496 i/o Box??
How did it happen ? Did you touch it ? Was it during using it ? By loading Scope project with luna I/O ? You are worrying me ! I've got 2 lunas since 2001 !ronnie wrote:Sigh!

Re: Have I killed my 2496 i/o Box??
I noticed that the power light was out. I unplugged and re-plugged in the cable. No joy. Did it again and then channel 3,4,and 5 lit up... but nothing was feeding those channels. Unplugged and plugged in again - it's possible that I plugged in the cable upside down!!!! No joy. Unplugged and re-plugged, lights flash red for a split second and that's it. That's what happens now. Maybe I fried something by plugging in upside down, on the Luna card or the box... the Luna works fine.. no Assertion failed on either the Source or Dest Z-Link modules. It's not a big deal, I have sufficient I/O but I just miss the box nice and lit up in the rack with the leds doing their thing when in use. I can't complain - it's lasted so long.

Re: Have I killed my 2496 i/o Box??
I opened the case and visually, nothing is burned or smells. As far as I can tell it looks brand new. I wouldn't know what to look for or try. I have a good meter and a digital probe somewhere. Any ideas? I miss ZLink, a really solid interface.
