Question about Accusine firmware update

[Stuart_Cheng]

Hi All,

One question about the Accusine firmware update. If we have Master + Expansion units, what is the correct procedure to upgrade firmware?

• Main control board -> Expansion control board -> Main HMI

or

• Main control board -> Main HMI -> Expansion control board

Thank you.

Hi,

I re-commend either way is okay to proceed for firmware upgrade. Both are okay to proceed.
