Description

Noise Rejection

Thresholds (hex)

Changes the lane

sensitivity. The

Unfiltered row is

the threshold level

that is set during the

configuration, before

any filtering has been

applied. The Filtered

row is the threshold

level that is set after

the sampling and

filtering of events and

background noise has

been completed.

If the sensor is

overcounting, increase

the number in the

affected lane's Filtered

row; if the sensor

is undercounting,

decrease the number

in the Filtered row.

If you're getting

spillover because of

multipathing, increase

the Unfiltered row of

the affected lane.
