I did some testing this evening with the FTDI cable from DIYDrones, the FTDI cable from SparkFun, the OTI USB to Serial cable from Remzibi's OSD and the Prolific USB to Serial cable that Remzibi is going to start shipping with the OSD's.Turns out the FTDI's can be used to program the OSD and Remzibi's cables can be used to program the ArduPilot (with a little modification).To use the Remzibi cable on the ArduPilot, you'll need to cut off the shrink wrap where the wires go into the silver braided cable and expose the green, brown and orange wires. The orange isn't used (or soldered to anything internally). Use the wiring diagram below.Remzibi_Cable_To_ArduPilot.gifTo use the FTDI cables to program the OSD, you'll only need 4 wires. Use the diagram below.FTDI_OSD_Cable.gif
