Tip Strip: Assigns digital signal source to encoder Z signal
Detail: Signal directed to the EPT cam trigger input through an optional masking AND gate with either Cam1 or
Cam2. The EPT is configured via the Engine Position Tracking Setup window. This signal is applicable for encoder
patterns only. When the encoder is mounted to the crankshaft of a four-stroke engine, then a cam signal must be
provided to mask every other encoder Z pulse (FALSE = Mask, TRUE = Pass). When the encoder is mounted to the
crankshaft of a two-stroke engine, or the camshaft of a four-stroke engine, then masking may be disabled via the
Engine Position Tracking Setup window EncZMask control so that every encoder Z pulse passes through to the EPT
cam input.

Tip Strip: Assigns digital signal source to cam signal
Detail: There are two available Cam signal destinations named Cam1 and Cam2. Both have similar function. For
EPT encoder patterns, one of the Cam signals can be selected, via the Engine Position Tracking Setup window,
as the mask for the encoder Z pulse. For EPT N-M or N+1 patterns, one of the cam signals can be selected as
the direct EPT cam trigger input for four-stroke engine phase information. Other functions can be implemented on
the Cam signals for capturing the angle of the cam rising edges, configured via the Cam Phase Capture tab of the
Engine Position Tracking Setup window.
DIX_ChanX_DigChanAsn
Tip Strip: Assigns digital signal source to channel during Direct and TMP Modes
Detail: Up to twelve DI Driver channel destinations are available which will directly command the DI Driver channels
from the selected digital signal source. The application of these destinations depends on which DI Driver modules
are inserted in the assigned slots. In order to utilize this functionality, the associated DI Driver module must be
placed into Direct Mode or TMP Mode via the associated DI Driver Setup window.
