User’s Manual

The "Defaults" button sends a command to put the conguration
back to the factory default settings. If you have changed the baud
rate and have then pressed the Default button and suddenly nd
that the SI-3™ will no longer respond to commands; you need to
reconnect at 9600 baud before you can change the SI-3™ back
to your desired baud rate. The "Get Info" button retrieves the
present conguration from the SI-3™ and updates the displayed
conguration. This command can be used to resync the SI-3™ Cong
program with the SI-3™ if you’ve power-cycled the SI-3™ while it was
connected to the SI-3™ Cong program.
4.3 Conguration Notes
With the exception of baud rate, all changes occur immediately and
do not require a reboot of the SI-3™ to become operational. When
baud rate is changed it takes eect the next time the SI-3™ is power-
cycled.
• Please wait 2 seconds after the last conguration
command before disconnecting the power to allow the
SI-3™ to record the setting in ash memory.
4.4 Baud Rate
The "Baud Rate" can be 1200, 2400, 4800, 9600, 19200, 38400, 57600,
or 115200 bits per second. The SI-3™ always uses 8 bits, no parity, and
one stop bit for its serial port conguration.
4.5 Measurement
MPH = miles per hour, KPH = kilometers per hour, MPS = meters per
second, and FPS = feet per second.
4.6 Min/Max Speed
No vehicles will be reported outside the minimum and maximum
congured speeds.
4.7 Target Report
The Target Report has three selections. Choosing the "All" selection
will display vehicle speeds coming towards or away from the SI-3™.
