I know that the graphics on the soon to be released M2 are not comparable to a T4 but on page 12 of its user manual it shows a passcode that can be used. I am not familar with older RTI stuff(only been programming them for about 8 months) so I dont know if this is what everyone is talking about for security or not. If not, it is a step in the correct direction.
Don't read my answer. Someone else will go into great detail as to why I am wrong rather than answer the original question...
