Pino,
I don't have an IB to try any of this; however, as Bob noted, some of the BDL168 connection is working right.? Here are a couple of things to try:
1.? Check Op Switch settings 11 and 12.? You may have to set 11 on one board to make it a bus master.? You may have to set 12 on one board so that it terminates the Loconet.? The IB may already do these things.
2.? Check how the BDL168 is powered.? The manual requires 12-16 V AC or DC.
3. Finally, section 13 of the BDL168 manual has a trouble shooting guide.
