I'm installing an M1 system with 11 items on the data bus: 3 input expanders, 2 output expenders, and 6 keypads.
I want to use the M1DBH (data bus hub with RJ45 connectors) for a cleaner install and easier termination.
I would need to use two hubs to fit 11 devices, since each has 8 ports.
Each device will be home-run wired to the panel with new 22 gauge 6-conductor copper cable.
Grand total of all the wire lengths is well under 2,000 feet.
The Elk documentation says that I can have two data bus runs from the main panel.
It's also possible to chain together two of the M1DBH units by putting a short RJ45 patch cable between the last port from first M1DBH, to the 1st port of the second M1DBH.
Which would be better?
a. use one data bus feed, and patch the two M1DBH's together.
b. use two data bus feeds, and have a separate feed go to each M1DBH.
Does it matter??
Thanks in advance.
