MK2000CBM
Installation Bulletin / Reference Guide
Connecting Multiple Remotes to a Single LIM2010
Up to two (2) MK2000CBM remotes may be connected to a single LIM2010. MK2000CBM series
remotes utilize a special RS-485 protocol for communication.
Each remote must be assigned
a unique bus address for proper operation.
Follow the procedure below to change the ad-
dress for each remote indicator.
NOTE:
The connected LIM2010 will be assigned address 1. A single connected MK2000CBM
will be assigned address 2. This is the factory default and will not require the below procedure.
An additionally connected remote must be assigned address 3 and will require the following
procedure.
Step 2: Changing the Address of the MK2000CBM
Follow the below procedure for changing the communication address of the MK2000CBM.
Step 1: Wiring Modifications
All remotes and LIM2010 are wired in series with each other via each device’s “A” and “B” termi-
nals. ONLY devices at the beginning and the end of the chain require the termination resistor.
For the LIM2010, this resistor is activated via a switch on the device. For MK2000CBM remotes,
a 120 Ω resistor must be wired across the remote’s “A” and “B” terminals. Refer to Figure 4 for a
sample layout.
1) Hold the TEST and MUTE buttons simultaneously for at
least four (4) seconds. “SP” will display on both screens.
2) Push the TEST button until “Ad” is displayed in the top
screen, and two numbers (factory default “02”) is displayed
in the bottom screen. This number is the communication
address of the MK2000CBM remote.
3) Press the MUTE button. Press the TEST button until the
desired address is displayed on the screen. Press the MUTE
button to confirm this value.
4) Press the TEST button. “Ar” will display on the top screen,
and two numbers (factory default “01”) will display on
the bottom screen. This is the address of the connected
LIM2010 device. In most applications, this value will not
need to be changed. If so, skip to step 5. Otherwise, press
the MUTE button. Press the TEST button until the desired
LIM2010 address appears, and press MUTE again to con-
firm this value.
5) Cycle power to the MK2000CBM to finish.
