Refer to the CUeiVRChannel class definition and/or the "UeiDaq Framework
Reference Manual" for more information about these methods and their
accepted input parameters. Some usage examples of these methods are
provided in the following subsections of Section 4.5.

DNx-VR-608 Variable Reluctance Interface
Programming with the High-level API
Rev.2 Description
Number of teeth on the wheel for RPM calculation

(1...3599). Also used as N in N-pulse mode.
Number of missing or fused teeth (0...3).

Set rate at which data is stored in Timed Mode.

(Max 1000 Hz)
Switch the leading channel in Torque Mode.

Invert the Torque Mode input signal.

Enable FIFO writes with or without time stamps.

Set analog input rate for the entire board.

(Max 320 kHz).
Connect TTL digital input to counter/timer.

Enable alarm when no zero crossings are
detected at the input (must also set digital output

to one of the UeiVRDigitalSourceAlarm
enum values).
Enable alarm when sensor is disconnected from
input (must also set digital output to one of the

UeiVRDigitalSourceAlarm enum values).
Does not apply to TTL inputs.
Enable alarm when overspeed condition is
detected. Uses number of teeth and Z-tooth size
to determine if configured RPM is exceeded.

(must also set digital output to one of the
UeiVRDigitalSourceAlarm enum values).
Set the RPM overspeed limit on the channel.

Set the noise floor level to prevent stall and open
circuit alarms from triggering off of a noisy signal.

This is scaled to the input signal.
Enable high frequency FIR filter (26 taps) with

cutoff of 10-15 kHz
Set the timeout value (ms) when using TPPM

Mode. Extends the default time base.
