# [WIZ107/108/750SR Series] How to insert MAC address?

## Question

Asked by Edward on 2018-05-30 in General.

As below list, there are 2-ways to insert MAC address using WIZ750SR series and WIZ550 series.

1. WIZ750SR series.
   After upload firmware, If display from serial to this data (INPUT FIRST MAC?), Send to “MC00:08:DC:xx:xx:xx$0d$0a” data.
