RSS-2-300W Non-Contact Surface Velocity Radar
Warm up time
- The time after sensor power-up, during which all measurements are ignored.
This time is used to settle auto-gain parameters, Kalman filter values, averaging filter, and all
other operational parameters. It is recommended to set this value to a minimum of 5 seconds.
In extreme cases where a quick response after unit power-up is required, 3 seconds can be
used, with a possibility of losing measurement accuracy.

Velocity unit
- The measurement unit used to report the measured velocity value. For NMEA
protocol which is used over RS-232 connection, the velocity is reported as an integer value. To
preserve higher precision with integer numbers, the measured velocity will be multiplied by 10
for m/s, km/h, mph, fps and fpm when being transferred over RS-232. When mm/s and cm/s
units are used, the measured values will not be multiplied by 10. This application internally
handles the multiplication factor which is used over RS-232 protocol, and it displays the
correct values to the user.
#set_sensitivity=<0-8>
PGA sensitivity
- This parameter limits the maximum gain (amplification level) of the internal
programable gain amplifier. It is strongly recommended to use the default value 8, which
allows the internal signal amplifier to use the maximum gain when the reflected radar signal is
very low. Setting this value to a lower value is used only when the instrument is mounted very
close to the water surface, typically less than 1 meter, and in that case this parameter should
be set to a value 4 or 5.
Velocity min.
- Available only on devices with firmware versions above 6.3.2. This parameter is
used for setting up the minimum velocity value of interest.
#set_dead_time=<3-100>
#set_max_velocity=<value>
Velocity max.
- Available only on devices with firmware versions above 6.3.2. This parameter
is used for setting up the maximum velocity value of interest.
#set_min_velocity=<value>
Low power mode
- Available only on devices with firmware versions above 6.3.2. This
parameter is used for putting radar in low power mode.
