I can see the XPDR setting, but does it do anything else?
I'm thinking of buying my first two GF units and am trying to figure out how much long term use I'll get out of them, ie. will they be in the final config?
Current plan is 1 GF-46 and 1 GF-RP48. This seems to offer the greatest short term gain...but what can I do with that GF-46 in the final 'pit?

I already know I need at least one RMK-T8 unit for various switches I want working...no need to pay the extra cash for the boxed version.
