Firewire to RS232 converter, does it exist?

[The village idiot]

I'm looking for a firewire to RS232 converter, and can't seem to find anything. A few different google searches turned up nothing. The reason for the firewire to serial converter is I need the 12 volt supply from the firewire. If it wasn't for the 12 volt needs, I could use a USB to serial, as those are very common, but USB only supplies 5 volts (I think). So if anyone knows of a device, let me know.

You could try here: CCT Online they might have something. I've never seen one though

Hey

The village idiot did you ever find a firewire to rs232? - I need a device that can do that.

If anybody know somthing about this, please tell me.

Thanks

Nope, not yet.

if you grab the pinouts from a firewire cable can't you use that? i mean use a USB convertor alongside a firewire cable that is just providing power. or does it need to be a neat, one cable solution?

I wanted a nice single connection package. What I guess I may have to do is use a USB to RS232 adaptor and get a DC-DC voltage doubler to get the power. I really only need 7.5 - 12 volts, the thing that might make it fail is I need 400 ma at that 12 volts. Lower the voltage and raise the current draw. Now I would be at the limits for USB (I think). I need to look up the USB specs and see how many watts I can draw from a typical USB 1.1 port. I assume I will need about 5 watts at 10 volts, which should turn into a 12 watt draw on the 5 volt USB port (some lost to the DC-DC converter), just a guess.

Edit, well that option is gone, max current for USB1.1 is 100ma per device.

I hate to say it but I would just buy another monitor. Unless you're looking for a "can it be done" project. Have fun

Monitor? Who said anything about a monitor?

It is actually a colorimeter used in concert with software to make printer ICM profiles. But as I said in the last post, it looks like a dead end. Very odd since both 1394 and RS232 are serial protocols, just that one is balanced and the other isn't.

I was replying to the wrong post Not sure how that happened
