MoTeC ADL2 EDL2 - Manual (Page 20)

18 Overview
• Beacon: For connection of a lap beacon
Options
Note that the number of inputs that are available depends on which options
are enabled. See Appendix B: Options Summary for details.
Specifications
For full specifications see Appendix D: Input Characteristics.
Speed Inputs
The 4 Speed Inputs are identical to the Digital Inputs except that they can
also be configured to suit Variable Reluctance (Magnetic) sensors such as
some wheel speed sensors. Because the amplitude of the signal from these
sensors varies with speed of rotation, variable trigger levels are required,
which must vary with the frequency of the input signal.
The Speed Inputs can also be used with Hall Effect type wheel speed
sensors.
• Note also that the Pulse Width measurement method measures the high
time of the pulse rather than the low time as measured by the Digital
Inputs.
Options
All four inputs are available irrespective of which options are enabled.
Specifications
For full specifications see the Appendices.
Internal Sensors
The ADL2 includes internal sensors for battery voltage and internal
temperature.
Expander Analog Inputs
Up to two E888 or E816 expanders may be connected to the ADL2.
