ZPL for Aztec code with ECICs

Hi,

I'm trying to use Aztec Code barcodes with ECI codes in my labels, but I can't get it to work and I haven't been able to find any examples of this online. Can anyone provide an example? Is there some sort of escape syntax in the ^FD field that is enabled by setting the ^BO parameter ECICs = Y?

Appreciate any help!
