VIM Speed Inputs
The Speed inputs can be individually set to be used in one of the two modes:
Hall or Magnetic. The VIM Speed input can also be set to measure analogue
voltages. This is especially useful when setting levels for magnetic type
sensors since the measured voltage can be used to determine the voltage
levels to use for the mag levels.
Note The same pin is allocated twice in the VIM, one input is when the pin is
being measured in analogue voltage mode. The other input is when the same
pin is being measured in a digital mode.
In Hall mode, a 4700 ohms pull-up resistor is connected to 5 V and the trigger
level is set with a single Hall Voltage Threshold setting.
In Magnetic mode, the pull-up resistor is disengaged and the trigger levels
can be varied depending on the input frequency.
Update rate is 100 Hz for speed measurement.
