Description
The OmniLT Version 2.6 firmware adds the following new feature:
•
Support for UPB (Universal Powerline Bus) Technology
About UPB
UPB is a new powerline communications standard for lighting and home control. UPB is a robust, two-way digital powerline carrier
communications protocol which transmits signals over the existing wires in a home.
UPB signals are transmitted using a digital pulse (pulse position modulation) instead of a 120 kHz tone over the existing house wiring.
The UPB pulse has a broad frequency spectrum, about 4 to 40 kHz, which travels better on the powerline. Attenuation on the
powerline is lower at UPB frequencies and less susceptible to noise. UPB can coexist peacefully with X-10 systems, intercoms, baby
monitors, speakers, etc. that communicate over the powerline.
Using a Powerline Interface Module (PIM), connected to a serial interface module, OmniLT sends UPB commands over the existing
electrical wiring to special switches, modules, and keypad controllers (UPB devices) that are designed with UPB technology. UPB
switches are two-way devices, so OmniLT knows the actual status of the switch when it is controlled locally. In addition, UPB
switches, modules, and keypad controllers can be used to trigger macros in the OmniLT controller.
Each UPB installation has a Network ID that serves to link all of the switches, modules, and keypad controllers to each other and to
the OmniLT controller. Under the Network ID, each device has a unique address. The address is used to send on, off, dim, brighten,
level, and other commands to an individual UPB device.
In addition to its address, every UPB device can be assigned Links, in the range from 1 to 250, which are used to create virtual “links”
between UPB devices. OmniLT can be programmed to receive Link commands (On / Off / Set) from UPB devices. It can also be
programmed to send Link commands to devices on the UPB network. Links can also be used to create “lighting scenes”.
UPB devices must be “initialized” or “set-up” using a software program called UPStart. With the PIM connected to a PC, each UPB
device is programmed with the Network ID, Unit ID (unique address), and other information. The software is also used to operate and
test the UPB network.
The OmniLT controller can:
¾
Send commands (on, off, bright, dim and level) to individual switches and modules
¾
Receive commands and status from individual switches and modules
¾
Send commands to keypad controllers to change scenes and control LED backlight behind the keys
¾
Receive commands when buttons are pressed on keypad controllers to activate controller macros
¾
Send Link commands to switches, modules, and keypad controllers to activate scenes
¾
Receive Link commands when a button is pressed on a switch or on a keypad controller to activate controller macros
¾
Send “Status Request” messages to switches to update their status in the controller
¾
Receive the UPB Acknowledgement pulse that indicates that a switch has properly executed a command
