Hi,
in general the Pins 1 (GND), 2 (operating voltage) and 3 (Data) need to be connected. There is a picture in the manual showing the PIN Configuration.
In addition we do have short bus cables available. When using these cables only the 3 color coded cables need to be connected to your installation.
When you use this 3 lines only one of the IRTrans devices needs a power supply. If you only have 2 lines (GND / Data) each IRTrans device needs a power supply.
