The problem you are going to have with a rig like this is to get the terminations at the right places, this is the one thing any 'problem solver' that see your rig WILL screw up.

Many thanks Erik, you are so helpful as you had been ever.
I thought, I should have placed the terminator resistors to the ends of the bus. (the cat5_cable lenght is about 1000 meter and rate is 56Kbps or less)

Any way that I can calculate or estimate the location of the termination resistors?
