If the RS-485 connection is working, then during firmware update, the hybrid app will show the progress bar making progress. Pretty much any RS-485 adapter will work.Is there any way to know if the RS485 connection is working ?
Will "any" RS485 adapter work or do you need a specific version to work with the program ?
I think got the wrong one, XDS100 vs XDS110
Can you tell me about the special cable that you were talking about ?
Here is the super hard way to flash the .out firmware and recover from a failed .out firmware upgrade if all the above suggestions fail. The XDS100 should work the same as the XDS110. You'll need Uniflash to upload the .out file. You need to disconnect all power from the inverter, disconnect both power connectors from the control board. Near that two-pin power connector, there's a relay. Remove the two-pin jumper next to the relay. Power the two-pin AC port with DC 220-350V (needs roughly 20W). It must be DC. AC will be bad, even though it runs on AC during normal operation. Connect your programmer to your PC and to the white 4 pin connector on the control board; it's toward the middle of the board on the edge closest to you. Left to right pins 1-4 are TCK, GND, TMS, 3.3V. See pages 97 & 98 for more necessary info on the connections. Flash the firmware using UniFlash. (The first time you use your programmer, it will probably update the firmware on your programmer.) Then disconnect and put all connections back to how it was.
