UPB.... What is a "channel"?

[BobS0327]

I've been reviewing the Upstart Export File Description version 5.1.  The description references a "channel" record as follows:

 

Channel Info Record (8)
•Channel # (0 = channel 1, 1 = channel 2, etc)
•Module id
•Is dim enabled on this channel?
•Default fade rate for this channel is dim enabled or zero if no

 
 
I'm just not sure what this is or how it's used.  Thus, can anyone provide more info on the UPB "channel"?

It is for devices that support more than one load.  With more than one load, you cannot just command the device on/off as it wouldn't know which load to control.

Look at the Simply Automated UMI-32 for an example.  Its a discrete 3-Input/2-output module.

Now everything makes sense.  Thanx guys for the info.

For compatibility sake, I think they should have an option to use multiple unit ID's for those devices.

I would like to see that as an option.
Essentially make the firmware believe it is two independent devices.
That would help compatibility with the Omni.
 
Right now I do a bit of translation through a RUC, which does send channel specific commands.
 
I have my porch and carriage lamps wired to a SA US22-40 switch.
 
I want to blink the carriage lamps during an alarm.
 
I can't send a unit blink command from the Omni to the US2240.
The Omni sends an Alarm Link to turn all the lights on during an alarm.
I have the RUC send the channel 1 blink command when it receives the Alarm Link.
It's a bit kludgy, but it works.
