Thanks for all the great info in this thread - this place is a gold mine of useful information. :)

Is there a list of what changes each firmware version introduces? I've got a BFD with v1.0 firmware and was wondering what's changed (besides the MIDI fix in v1.4 I guess!).

I'd be interested in the differences between each firmware also... just incase someone had called behringer or got the information with them please post it here.

I got my 1.4 chip but not in a hurry to install it. I've gotten used to manually entering the data into the BFD and figure I might as well save the $40 on the MIDI cable... still undecided though.

BTW, after I replace the chip will I need to reprogram all my filters in the BFD? Or is that stored in a different chip in the BFD?
Hi all - funny, I came here with the questions quoted above and found that I already asked these 3+ years ago but did not get a response. :) I'm finally getting around to automating the filters over MIDI (been entering them manually but its so much fun).

A few questions please:

A) Does anyone know if I'll have to reprogram the filters after replacing the EPROM? I'd like to swap out the chip with the 1.4 version just to get that step over with, but not ready to do any filter work and don't want to loose the settings.

B) Are there now cheaper (than $40) options for USB MIDI interface cables? I'd only be using it with REW so no need for anything fancy.

C) This guide http://www.hometheatershack.com/roomeq/wizardhelp/help_en-GB/html/bfdcomms.html#top explains that you must enable the STORE mode on the DSP1124P for each calibration setting. But it doesn't explain HOW to do that (unless I'm missing it)? It says to push the store button twice but that sounds like its to do it manually...?

Thanks!

Yup, you're missing it :) Read step 5 of configuring the DSP1124P and then read through item 1 in the notes.
So are you saying that step #5 in the list of #1 thru #6 is an independent step. So I do steps 1-6 one time. And then for all future sessions just do step #5?

If you turn the DSP1124P off it forgets the store enable setting, but it remembers the others. You will not have to change any values for the other steps, but the way the DSP1124P works you have to go through them to get to the store enable. If you leave the DSP1124P on all the time you will not have to do anything after the first time.

Are the 1.4 chips still available from the factory? I have a 1.3 box. Not using the MIDI store right now, but never hurts to start looking for the parts...

How to open up the unit?

Hi All,

What are the minimum screws I need to use to open up the unit to get at the 1.3 EPROM to replace it? Someone asked how to open the unit up on page 5 and was told to use a drill and a hammer. :) Other than that I didn't see any mention of how to get to the chip.

I'm the type that opens things up and after putting them back together I have a few screws and springs left over. :) So I want to be sure to go about this the right way.

In looking at the unit I see it has 3 screws along the top, and three screws along the top of the back lip of the top. Do I just remove these 6 screws and the pull the top off and have access to the chip? It looks like the top lip slips behind the black plastic from where the AC cord goes in so I assume I don't have to loosen that.

There are also four screws on the bottom (including the grounding screw). And several screws along the back (below the lip of the top) which surround the various input/output ports. I assume none of these need to be loosened or removed?

Any tips or advise is greatly appreciated. My BFD is an invaluable piece of equipment and I'm worried I'm going to mess something up! Thanks!

OK I figured it out. Its the top 3 screws and the 3 screws on the top of the back (lid top edge on back). It was actually pretty tricky to fit the pins in because they were much wider than the sockets. I understand a little wider, but this was much wider. And much wider when compared to the pins on the 1.3 EPROM I removed.

To get it to fit I carefully laid a row of pins on a table and applied pressure pending them all down evenly. Then repeated for the other row. Just doing a little at a time and aligning it with the socket to see how much more was needed. After a few tries I had it so it fit snug with a little pressure. Considering I got this chip 3 years ago and am just putting this in now, I may be the last one to be installing the chip, but wanted to pass this info along anyway. :)

I'm still trying to find a v1.4 chip. Where did you get yours from? Hopefully these things haven't disappeared. I have an eprom programmer and some software from other projects if I need to go that route. Thanks

I got mine from Behringer about 3 years ago. Just never motivated to install it until now. Not sure if they still have them available but maybe try giving them a call. Also if you read back through this thread (I think early pages) you'll find someone who had them available for $10 each. Maybe he still has them or can make them.

Is it safe to say that any new DSP1124Ps purchased from a store/Amazon would have 1.4 firmware? Do we know when they started shipping with 1.4?

My new 1.4 chip from eprompro was delivered today. Going to crack the case on my BFD tonight and see what I'm getting myself into. I'll take pictures and post them if I can get to it this week.

It depends on how long they've been sitting on the stock. My GUESS is that you will be ok and get 1.4. I say this because from what I recall I got mine around 2003 and that was about the tail end where they stopped shipping with 1.3 and made 1.4 available. Worse case scenario you can pick up an eprom for about $10 and pop it in yourself. Yea its a bit of a hassle but not worth worrying about.

I think you'll find it pretty straight-forward. As I posted above, the only thing that was a bit complicated for me was that the pins on the Eprom (which i got direct from the manufacturer) were significantly wider than the pin holes.

I realize that this is partially by design, so that they fit in very snug. However in my case there was no way to fit them in the way they were, spread pretty far apart like that (the two different rows, that is).

I handled it (which I think I detailed above) by laying the chip down on a flat table with one row of pins laying against the table, and then I pushed down and forward on the chip, using the table as a way to bend the pins evenly. I did it a tad at a time to each side. Then tried putting it into the socket. Then repeated just bending a little at a time until the spread was just right to fit in and yet still be snug.

It just took me 15 minutes to upgrade my chip from 1.3 to 1.4. I took pictures, but honestly it was WAY to easy. There really isn't much inside the BFD, the chip is very easy to find. Took me longer to carefully remove the hot glue on the socket than anything else. Looking forward to trying MIDI to update my filters!

My hot glue just popped right off as one clunk with just a little bit of pressure

I'm curious - did you have to squish the pins in quite a bit like I did (read post above)?

Yes after years of manually entering filters it is nice to finally have the MIDI support. What MIDI device did you get? I got the Sport Uno and it works great with the latest drivers from the company's web site on Win 7 x64.
