ILH TCAS in P3D

Until P3D 3.1 Lee Hetherington's TCAS II v7 IVSI and Transponder gauge was compatible with P3D.

Something changed in 3.2 and since then the transponder appears just as a brown background rectangle without any functions.
The IVSI works but in Squawk Standby mode.

I know ... its from FS2004 era but ... it still worked fine in P3D 3.1 well and it is a VERY useful gauge in implementing TCAS and Transponder with Mode C, Standby & Ident in old aircraft add on's which have analogue gauges.

This enables pilots flying on line (VATSIM & IVAO) to have in cockpit Squawk and TCAS controls.

Is anyone using it in P3D ?

If not is there an alternative which includes Transponder and TCAS IVSI gauge ?
