 3) 64-group serial data mode  

 

Supporting 64 sets of serial data, defined as follows:  

 

Under serial mode, there are 64 data cables totally. Each cable can drive one LED bar independently.

In case of horizontal LED bar, the default is that Data1 drives the first row from the top and Data64 drives the 64th row. (front view).

In case of vertical LED bar, the default is that Data1 drives the first column of from the left and Data64 drives the 64th column. (front view).
