Due to the reversals on PulseGuide in the SiTech and PlaneWave STI (which is a derivative of SiTech), the guiding logic in ACP has to be modified to compensate. See this Comm Center thread by Jeffrey Jongmans. Also, in PlaneWave STI (Davie Mittelman at NMS) it required "Reverse dec pulseguide commands pointing west" (only) and for the conventional guiding in AcquireSupport, reversing Y instead of X
