Beginner questions re upgrade discussion

[AndyB]

Hi,

Please excuse me if I am asking questions that you think are obvious and have been answered. The more I read, the more I get confused.

I have 2 Diablo wireless Cams and a TwinBase Version 2.22.

I have read that "old" CAMs can be fed with Underworld files - as they are in .dup format I would have to do a re-write and this would function with some restrictions.

I have also read that "old" CAMs should be upgraded to a Version 2.3.

My questions:
1. can I write an Underworld .dup into an "old" CAM?

2. how can I find out what Version 2.3 means? The version of what? I only found I have a BootVersion 1.41.

3. is it true that I can't upgrade my CAMs to a 2.3 using TwinBase, but only a CAM programmer (Cas Interface 2+Plus, Cas Interface 3 or Cas Interface 3+Plus)?

Please bear with me as I am not just asking this out of laziness, but really information overload and half-knowledge.

Thank you
