The M1DBHR is an "active" RS-485 data bus hub designed for jobs where an M1 Control is retrofitting an older panel that has multiple homerun 4 conductor keypad/data wires.
It splits the main 485 data bus into 4 managed 485 branches.
Each branch can have 2 parallel home run cables for a total of 8 home runs.
The end of each cable is EOL terminated to ensure proper operation and supervision.
