The configuration software saves your settings and opens with the settings that were last made to the SI-2.
Serial Number
The Serial Number box shows a digitally encoded serial number of the SI-2 you are connected to.
Speed Setup
You can select the Speed Setup to mph or kph for the following speed ranges. The ranges are determined by
the hardware and can not be altered by the configuration program.
Low
High
Sensitivity Value
The Sensitivity Value slider bar ranges from a minimum of 1 (least sensitive) to a maximum of 17 (most
sensitive).
Rate of Update
This slider bar sets the rate that you want the speed to report (polled, at a fixed interval, or when the speed
changes). If you set the slider to Min, the speed rate will update when polled, or you can move the slider to the
right to set how many times (between 1 and 10 times per second) you want the radar device to report. You
can also set the device to update only when the speed changes by moving the slider to the far right position.
Override Update Rate
Checking the Override Update Rate check box lets you override the update rate with a value ranging from 1
to 100 in 1/10 second intervals between updates.
Data Hold Time
The Data Hold Time lets you set the time (from 0 to 10 seconds) to continue reporting the last valid target
after it is lost and no new target is replacing it. In other words, the speed will display for the set time until a
new target speed replaces it or until the device reaches the set time. If there is no new target speed after the
data hold time elapses, the software will report a 0.
Zero Report in Continuous Mode
If the Zero Report in Continuous Mode check box is checked, the system will send zero speed packets every
two seconds when a valid speed target is not present. This mode only applies if the unit is set to update only
when the speed changes. (Note: This is the speed before the cosine error corrections are applied.)
Low Speed Cutoff
The Low Speed Cutoff option is the lowest speed within the valid speed range that you want the SI-2 to report
(see the Valid Speed Ranges above.) Be sure to enter a speed that is less than the highest speed. (Note: This
is the speed before the cosine error corrections are applied.)
High Speed Cutoff
The High Speed Cutoff is the highest speed within the valid speed range that you want to report (see the Valid
Speed Ranges above.) Be sure you enter a speed that is greater than the lowest speed.
Cosine Correction Angles
To correct cosine angle errors to adjust for the correct speed, set the Cosine Correction Angle boxes to an
angle, between 0° and 45°. You can correct for one or two angles.
Valid Speed Ranges
1-70 mph
2-110 kph
5-200 mph
8-320 kph
55
