Odd Hardware Utility Issue

[nallja]

Hello all;

I've been using LOR controllers for 6 years now, this year we had a major storm roll through and knock out a couple of the IC's on 2 of the boards.  All the boards are working again but the hardware utility seems to have some issues seeing all 4 boards in certain setups.

If I connect the boards in order of ID number 1 -> 2 ->3 ->4 the hardware utility only sees boards 2 and 3. 

If I connect the boards in order of ID number 2 -> 3 ->4 -> 1 then the hardware utility can see all 4 boards.

If I connect the boards in order of ID number 3 -> 2 ->1 -> 4 then the hardware utility can see all 4 boards.

If I connect the boards in order of ID number 1 -> 3 ->2 -> 4 then the hardware utility can see 1,2,3 but not 4.

If I just connect board 1 the hardware utility sees it just fine.

If I connect them board 1 -> 4 the hardware utility sees both boards.

This is not ideal as the controllers are spaced out in the yard and I would need more Cat5 to double back. 

Any thoughts would be appreciated because I am baffled.

Boards are as follows 1,2,3 are CTB16DV6, 4 is CTB16PC V1
