  1. UPB can be controlled by communication to the PIM/CIM RS232.
  2. All UPB devices use the same protocol.
  
  The protocol is very confusing as it is written in a style like machine language (literal hex strings).
  
  GSLogic has a module for sale which has two-way communication to all devices, loading device name/location, used defined Groups/Links (scenes), and user defined on/off/sunset/sunrise.

  Yes you could adapt this for Duet use.

  This may be a bit late, but UPB is very controllable from Netlix via serial commands. It took a while to get the hang of the protocol, but is is quite good once you get it. It gets more complicated if you want to track actual lighting levels.
  
  You will need a transmit queue for outgoing commands.
  
  I wrote CALLs for various functions like device or link level changes, status reads etc.
  
  Prepare to use the FORMAT statement when writing your strings.

  Here is an example call for sending a link to a certain level:
  

  DEFINE_CALL 'UPB LINK GOTO'(nLINK,nLEVEL)
  {
  SEND_COMMAND vdvUPB_Q,"$14,'8800',FORMAT('%02X',nUPB_NID),FORMAT('%02X',nLINK),'FF22',FORMAT('%02X',nLEVEL),FORMAT('%02X',256-((nUPB_NID+nLINK+425+nLEVEL) BAND $FF)),$0D"
  }
  

  
  I am sending the commands to a queue (vdvUPB_Q), not directly to the PIM module.
  
  nLINK is the link I want to change and nLEVEL is the level I want it to go to.

  That will definitely take some time to digest!
  
  What's the comm set up and pin out for the PIM?

  9600,N,8,1 straight cable
  
  One pin of the pim has to be held high for it to transmit to you.
