The ideal way to connect multiple home run cables is with an ELK-M1DBH Data Bus Hub. It accepts CAT5 or CAT6 cable with RJ45 plugs on the ends. It
does all the work of series connecting the DATA lines A & B. Terminate at the hub using the included RJ45 Terminating Plug in the first unused jack.

Setting the Data Bus Address and Enrolling Device(s) into the System
Keypads and expander devices communicate with the M1 over the RS-485 4-wire data bus. Each device must have a unique
address setting (from 1 to 16) within it's device type. Keypads are device TYPE 1, input (zone) expanders TYPE 2, output
expanders TYPE 3, etc. The purpose of device types is so that the address numbers can be re-used in each different device
type. It is OK to have a Keypad, a Zone Expander, and a Output Expander all set to address 2 and on the same data bus since
each device is a different device type.
It is NOT OK to have duplications of addresses within the same device type. I.E.
Multiple keypads on the same control cannot be set to 'like' addresses.
ADDRESS:
From the factory all keypads are set to address 1. Valid keypad addresses are 1 to 4 for the ELK-M1, or 1 to 16 for
the ELK-M1G. The first keypad on the system (Keypad 1) is automatically enrolled upon power up. Each additional keypad must
be assigned a unique address and then manually enrolled from “Menu 1 - Bus Module Enrollment”. (See M1 Instruction
Manual, Menu 01, for complete instructions on Bus Module Enrollment)
1. Press and hold the " * " key, followed by the F5 key . HOLD BOTH keys pressed for 5-10 seconds or until the LCD displays:
Exit when done. F1 Set Addr.
(This is Keypad setup mode)
NOTE: This mode may also be accessed by removing power from the keypad (unplugging the data bus cable) and then
applying power while holding any key pressed.
2. Press the F1 key to display the current address setting.
3. Set the desired address by entering a number from 1 to X.
4. Press the Exit key when done.
