you could check your controller for two reported connectivity issues:
-
There can be connection problems with the breakout board adapter not reaching the contacts inside D-Sub connector on Onefinity Controller due to too long jackscrews on the D-Sub connector
-
More recently there was a problem reported with the D-Sub connector soldered into Onefinity Controller Mainboard, problem could only be resolved by resoldering the solder joints on D-Sub connector pins on Onefinity Controller Mainboard
