vp-890 dead, any hope? Reply

Hello everyone,

I was updating the firmware of the vp-890 (soft v 4.3.2) when I got messaage "Program file" and that was all. Now when I try to connect it, usb port doesn"t recognize it. I believe the software wasn"t written correctly and that is why mcu is dead now, hence USB interaface. Can anyone tell how to solve this issue, has anyone faced it?

Any help will be greatly appreciated.
Warm regards,Roman

If your programmer that had the function of update online lost its program, you can resume it:

1 Open the cover.

2 Find JP1(J1), short circuit. Connect with PC and wait for communication is OK while the LINK LED is bright. Then take out short circuit on JP1(J1).

3 Enter WELLON’s system, updating the firmware. When update is OK, exit system.

4 Off Power,and on power again, enter WELLON again.

Dear friend,
thank you for the reply. I did it exactly how you said. It didn"t make any changes. The LEDs are dead and it is like shorting jumpers or not makes no difference.
What else can be done?
Thank you again for your quick reply and support.

thank you for your quick reply. Could you please tell where to send it and how much time and money it will cost us? It was bought from your ebay reseller for about year ago or maybe a few month more. Warm regards, Roman
