ELK-M1DBH Data Bus Hub for E27 or M1 Controls

The ELK-M1DBH from ELK is a data bus hub that gives E27 or M1 control systems a single, tidy point for connecting expanders and keypads. It takes up to nine RJ45 cable runs and ties the data A and B lines together in series, so the bus can be terminated properly. It suits installers wiring home-run cabling into a structured wire box, and extra hubs can be added when nine connections are not enough.

Key features

• Accepts up to nine data bus connections for home-run cable layouts.
• Internally connects the data A and B lines from the previous device in to the next device out.
• Multiple hubs can be connected together for expansion.
• End-of-line bus termination can be done on the board, and an RJ45 terminating resistor plug is included.
• Input connections are elevator screw terminals, and outputs are RJ45 8-pin jacks.
• A mounting plate is included for structured wire boxes.

Installation notes

Plan the home-run cable paths to the hub before mounting, and secure the mounting plate inside the structured wire box so the terminal side stays accessible. Terminate the bus at the last device on the run, either on the board or with the supplied RJ45 terminating resistor plug, and confirm that every expander and keypad communicates before closing up the enclosure.
