roland FC100 midi controller - rewiring, need help!

[burgiedanny]

me too!!

HI guys, I just bought a fc 100 on e-bay thinking I was gonna control my boss gx 700 with it. Much to my surpries the cable doesnt fit! If I do this mod will my fc100 work with my gx 700 which has the midi plug in back?

has anyone else done this

So has anyone else done this mod? I'm haveing some problems with the posted diagram, I just wanna know if somebody else has had success with this. I can't seem to get a hold of collen to clarify the diagram for me. It seems that the numbers on the diagram and the numbers on the actual board do not match.

TX+ to 5 pin MIDI DIN is that right or is it pin 4.
Dose "220 ohm pullup" mean that ther is a 220ohm resistor between tx+ and midi din

here's the pinout for anyone else who needs it, and cant get the word document:


1___________ RX
2___________no function
3___________Vin +10v <<<< To DC power plug
4___________signal GND <<<< To DC Power Plug
5___________TX - (midi out) <<<<< to 5 pin MIDI DIN
6___________TX + (220 ohm pullup) <<<<< to 5 pin MIDI DIN

pin numbers are for FC-100 end (looking at rear of FC-100)

How I did it

O.K. I rewired my (RRC) fc-100 to work with my (midi) boss gx-700 and it works great. Here's the deal, I don't know how it worked for anybody else but the original document posted by Collen was all wrong for me. If you look on the actual circuit board the pins for the RRC plug on the back of the fc-100 are labled differently from the document posted by Collen and if wired like the document says, it will not work. So, here's how it worked for me......looking on the actual board of the fc-100 behind the RRC plug........Pin #3 is the DC + or (vin +10v)........Pin #4 is the DC- or (DC signal ground)........Pin #5 is the midi - or (TX-)........Pin #6 is the midi + or (TX+).............If you just want to rebuilt the cable to work (which is what I did) you won't have to take the circuit board out. Here is how to do it with the document provided by Collen..............Pin #3 is the DC +........Pin #2 is the DC -..........Pin #1 is the midi -.........Pin #6 is the midi +.........The midi out pinout diagram on the document seems to be O.K. I used a 9v dc 400ma power adapter to power the fc-100 by wireing a female dc plug into my RRC cord just below where I wired the new midi plug. Now I just plug in the 9v power into my RRC cord and plug into my gx700 midi input. Good luck!

roland FC100 midi controller

HI i HAVE A roland FC100 midi controller RRC CONVERTER AND A BRAND NEW CABLE ALL FOR 150 FIRM EMAIL ME AT CH898@HOTMAIL.COM

[trevcda]

Great thread! I've been wondering how this cable worked and what made it so special. I was really surprised to find it was just power and MIDI configuration. Knowing that now, has anybody tried using a seven pin DIN jack (like 5 pin 180 degree + 2 pins; will accept a MIDI plug) and running phantom power over a seven pin MIDI cable from the rack? Has anyone sourced a seven pin MIDI jack that will fit the FC100 series pedals circuit board?

Something else that occured to me; the FC100mkII has a tuner out doesn't it? I haven't looked at mine in awhile. Wouldn't the MIDI conversion defeat this tuner output?

I know this is an antique thread, but I found this site via looking for this info. Is pin 1 doing anything in the conversion? I am a total n00b to midi.

Diagram is ok, I've finished and it works! Thanks a lot for posting this. I've connected brand new DIN out instead of the RCC out.

There is a little problem if You wanna leave this RCC and "rewire" the cable, because the RCC pinout (last diagram) might be wrong. As you can see, the numbers in the "other side" of PCB (printed circuit board) are listed in the document:

3 -> 10V DC +
4 -> 10V DC -
5 -> TX - (pin 5)
6 -> 220 ohm -> TX + (pin 4)
GND -> midi shield (pin 2)

Don't forget about GND (it's very well described in the doc).

Sorry for bad english, i'm from Poland Greetz!!

No, it's "empty pin". Is not doing anything.

Hi guys, my first post here and only because I was thinking about the same thing - I've got an old FC100 lying around and I thought I could use it as an extra midi contoller. Following on from the last post, a couple of things occur to me.

I was really surprised to find it was just power and MIDI configuration. Knowing that now, has anybody tried using a seven pin DIN jack (like 5 pin 180 degree + 2 pins; will accept a MIDI plug) and running phantom power over a seven pin MIDI cable from the rack? Has anyone sourced a seven pin MIDI jack that will fit the FC100 series pedals circuit board?

There's no need to go to all that trouble. The 'standard' 5 pin DIN used for midi, only uses three of the connectors, the other two are spare. You can remotely power the unit using these spare wires. I have a MidiBuddy controller that does just that (not modified at all, it came from the factory that way.

If you don't actually need the RRC output, then the easiest thing to do is to chop the plug off one end of your RRC cable and rewire it to a 5 pin DIN.

Something else that occured to me; the FC100mkII has a tuner out doesn't it? I haven't looked at mine in awhile. Wouldn't the MIDI conversion defeat this tuner output?

It's so long since I used my FC100 I can't remember everything about it. I originally bought it when I bought my GR50 (that's still around here, as well ). However, I don't think the FC100 has the tuner built into the pedalbard, just an access to the tuner built into whatever it's connected to - but I could be wrong about that, so don't take it as gospel.
