How to recover MC050-120 after power supply shutdown during software downloading

[anpham]

Hi,

I had an accident with the power supply during software downloading to MC050-120. I tried to used the "System/Recover ECU" to recover it but was not successful.
Is there anyway other way to recover the MC050-120?

Best regards,

Hello anpham,

This sounds strange.  Does the Service Tool state that the unit is in Bootloader or isn't the unit found?

Some things to check.
- Recovery ECU  (already done)
- Check cables and connectors
- Test with a second controller to check that all connections and tools are working.
