M1XSP Installation Manual
Page 14
Centralite is a low voltage, centrally controlled, whole-house lighting product. The Centralite load center is installed near the
circuit breaker panel. It contains a processor board with an on-board RS232 serial port for interfacing with the ELK-M1XSP, and
then into the M1 line of controls. The M1XSP supports 192 Centralite individual loads (dimmers, relays) and 64 Centralite
scenes. Integration with the M1 is accomplished by "mapping" the Centalite loads to M1 Lighting devices. For example:
Centralite individual loads 1-192 are mapped to M1 Lighting devices 1-192. Centralite Scenes 1-64 are mapped to M1 Lighting
devices 193-256. The attached chart shows the M1 Lighting devices and their corresponding Centralite Load/Scenes.
Components required for Centralite integration:
- An ELK-M1 or ELK-M1EZ8 Controller.
- One (1) ELK-M1XSP Serial Port Expander. NOTE: Firmware updates may be downloaded from the ELK M1 Dealer Web site.
- One (1) Centralite LiteJet System with integrated processor board.
- One or more Centralite wall switches.
Limitations:
- Button presses from a Centralite keypad have no direct integration with the M1. However, it could be possible to assign a
button to a non physical (phantom) load and then use the status change of that load to cause an M1 action.
- Load status changes from Centralite to the M1 requires special firmware in both products. See paragraph titled "Load
Status Communications". Even so, in many circumstances it may not be possible for the lighting status displayed by the
M1 Controller to match the true status of the loads.
Setting up the M1XSP and the M1 to communicate with Centralite
1. Install the ELK-M1XSP per the instructions on page 3. Be sure to enroll the device into the M1.
2. Connect the female end of the supplied 9-pin serial cable to the M1XSP and the male end to the 9-pin serial port on the
Centralite processor board marked "RS232-2".
3. Set MODE Jumpers on the M1XSP to a value of 1 1110: S4*="1" (UP), S5="1" (UP), S6="1" (UP), S7="1" (UP), S8="0"
(DN). NOTE: Some units do not have jumper S4.
4. Set the M1XSP Jumper JP3="232". The position of BAUD jumpers S1,S2,S3 does not matter.
5. Power up all the devices.
6. Program the M1 Lighting device attributes utilizing the ElkRP software. Only the specific devices to be used for Centralite
need to be programmed. For individual addresses program M1 Lighting devices: 1-192 "Format=Serial Expander" and
"Type= Dimmer" (Type may also be programmed as "On/Off Switch" if the device isn't dimmable). For the scene
addresses program M1 Lighting devices: 193-256 as "Format= Serial Expander", "Type=On/Off Switch".
When a M1 Light device is activated from a rule or from the M1 Keypad "Automation" menu, the corresponding device command
will be sent from the M1XSP to the Centralite Processor. NOTE: Dimming from the M1 Keypad can only be done using a task.
Load Status Communications:
To receive load status changes from Centralite requires firmware ver 1.0.14 or later in the M1XSP and ver 5.5 or later in the
Centralite LiteJet. Turn ON dipswitch 6 on the LiteJet board but DO NOT program the load "send changes" option.
Note: Version 5.5 or later of the Centralite firmware places a 1 second delay between each load change transmission. This
means that multiple load changes can and will take several seconds to reach the M1. An ALL ON command could take well
over a minute for all loads to report in.
Recap of Centralite Commands supported by M1:
Centralite commands sent by the M1XSP: ^Annn<cr>=Load ON, ^Bnnn<cr>=Load Off, ^Cnnn<cr>=Scene On, Dnnn<cr>=Scene
Off, and ^Ennnllrr<cr>=Load, Level, & Ramp Rate. Where "nnn" represents the load or scene 001-256, "ll" represents the dim
Level 00-99, and "rr" represents the ramp rate 00-31.
