So agree with u...?
"As the saying goes.. just because you can, doesn't mean you should!"?
It has no sense giving the option to a client to change a DM-NVX-363 from receiver to transmitter. Just decide the way u want to work in the project and that`s it. If you give that option there are more possibilities that the client don`t use it right and complain about the functionality.. programming is not fine.. and so on..
