Newbie M-Plus ISO/EIA Option

HI everyone,
I'm new to this forum but I've been reading threads for few years.

Here is my problem:
I have a VTC16 with a M-Plus controller. When I export my program with CAMLINK, the file extension is .EIA.

I want to transfer them in M-Plus format to be able to use DATA-Translate Matrix and une it on my Nexus 510.

Is it possible to disable this option or to change the file format?

Thanks for your help
