Seems that connection is fine but please confirm the following:
1. Without to have the DMX512 console connected (please remove the DMX plug) with Tristar, then you should get cycles of colors.
2. When you just connect the DMX plug (and console is powered on) then Tristar goes on Black-out.
3. About Address 44:
If you set ID 44 using Pavo controller then it means that the actual DMX512 channel that Tristar will respond (from your console) will be Address 130
With Pavo you actually set the ID of each Tristar; check example bellow:
ID001= DMX CHANNEL 001, 002, 003 (R,G,B)
ID002= DMX CHANNEL 004, 005, 006 (R,G,B)
ID003= DMX CHANNEL 007, 008, 009 (R,G,B)
ID044= DMX CHANNEL 130, 131, 132 (R=130,G=131,B=132).
HOW TO FIND THE CORRESPONDING DMX CHANNEL FROM THE "ID SETTING" (DONE WITH PAVO CONTROLLER):
EXAMPLE: ID44
44 - 1= 43
43 x 3CH=129 + 1= 130 (START DMX CHANNEL OF "ID44" IS 130)
MAXIMUM ID SETTING FOR ANY LAMP IS ID169 (DMX START CHANNEL 505).
