TL250 questions!

[Mlink <none@xxxxxxxx>]

If anyone is familier with the DSC tL250 I have a few questions that I
cannot find answers to on the web!

I have an older alarm system. The DSC 832.

Can I add a DSC TL250 to it for web communication and interface?

I use Macintosh computers.
If I can use a TL250 with the 832 will the "web" interface work from
the Macintosh platform?
Can I do firmware upgrades if they're needed?
The DSC website mentions of course that it is compatable with a slew of
Windows operating systems but, I'm used companies neglecting to mention
that "whatever" functionality is built into the Mac system and that
they will also work.
Unfortunately this may not be the case with the DSC alarm system...

Any help would be great.
I'l tried the DIY forums and found much info.

Thank!
Don
