I've used the Pixelnet and the DMX support with the Pi.  No problems.  Just be sure that the dongle is attached before your power up the Pi.

I'm going to try both of these devices:

and this one

I'd like to see how they work with the Renzilla minirenSISO, and also with the FPP.

gadgetsmith, how did these items work out for you?  Were you able to get DMX working from either of these items?  I would really like to have a simple solution for DMX output from a Pi or Windows computer.
I've connected the second adapter to Pi, and it was recognized, but never had time to test the output. Not sure if others have used that specific adapter, but there are similar adapters that people have lready proven to work with the PC or Pi. I'll will be testing these two specific adapters in the coming weeks and months, and while I fully expect them to work, I can't say for sure until I've done it.

Oops. Missed this.
Steve, are you using one of those two adapters I posted about? Thanks!

An old thread, but still relevant.

I have been able to use the Open Source "ft232r_prog" program under Linux to change the eeprom settings on this FTDI dongle.

I needed to change the C2 value back to the default TxDEN to enable the dongle to receive RS485 for testing something and I didn't want to connect the dongle to a windows machine, so I downloaded, compiled, and installed ft232r_prog on a Pi.  I made a note to think about including this in a future FPP image.

Hello

On the RS485 driver (75176B), there is a control line "tx enable". This line is used to activate the RS485 output of the chip.
To keep signal output active, you need to force this line to high level.
