    I think the M1DBHR is what I’m looking for, but I want to be sure before running any wires. Here’s the configuration…

    Box 1 contains the M1. I can put an M1DBHR in this box. It will also contain an M1DBH and all expansion cards in this box will go thru the M1DBH in this box.

    Boxes 2, 3, and 4 will all contain an M1DBH and one or more expansion boards. Each of these M1DBH’s will be wired to a data bus branch on the M1DBHR in Box 1 (each M1DBH will be on its own branch).

    Expansion boards, keypads, etc. can all be plugged into one of the M1DBH’s.


    Do I plug a RJ45 termination plug in the first unused jack on each of the four M1DBH’s?

    Can I use cat6 cable between the M1DBHR and the M1DBH’s? If yes, should I “pair up” the conductors or not use the extra four conductors in the cat6 cable? If no, what four conductor cable do you recommend, e.g., gauge, etc.

    I will keep in mind the possibility of needing separate power supplies.
