5.1.2.
Baud Rate (BR)
The Baud Rate is selectable via the serial interface and it requires the host device to change
its own Baud Rate after commanding the sensor to change.
The following Baud Rates are provided (with corresponding serial command):
2400 BR2400<Enter>
4800 BR4800<Enter>
9600 BR9600<Enter>
(default)
19200 BR19200<Enter>
38400 BR38400<Enter>
5.2.
Serial Data Output (SD, SF)
The Serial Data Format units, and errors are selectable using the Serial Output Control command.
Serial data is transmitted from the AR1000 as 8 data bits with no parity and 1 stop bit. The
sample data sent represents calibrated distance readings.
Available formats are decimal and hexadecimal
Output units are determined by the scaling factor. The nominal units (scaling factor = 1) is
meters.
Adjustable offset modes are Unbiased, Zero-Based, and Offset-Based.
5.2.1.
ASCII Output Format (SDd , SDh or SDs)
The factory default setting for output format is decimal (
d
)
SD selects between ASCII decimal (
d
) with distance only, hexadecimal (
h
) output or ASCII
decimal (s) with both distance and signal strength formats of measured value data. SD affects
all commands that output a distance value.
Decimal Notes:
Decimal (d) output values are based on units of meters (m) multiplied the scale factor SF.
Decimal output has an optional (-) sign, at least one digit before the decimal point, three
digits after the decimal point, and is followed by <CR><LF> (carriage return and line
feed characters).
Decimal (s) output values are xxx.xxx yyyyyy where x is the distance and y is the signal
strength. The range for the signal strength is between 0 ... 999999 and the values depend
on the measurement mode (DT, DS, etc.).
Due to the different calculation algorithms used in the different measurement modes, the
signal strength for a given distance and target surface may be different.
