RSS-2-300W Non-Contact Surface Velocity Radar
and reported. Geolux Instrument Configurator color-codes these
values. Measurements can be trusted when QoS is green. Measurements
may be inaccurate when the indicator is yellow or red.
Q2:
This is an indicator of the Quality of the Service (measurements)
related to the radar signals. Geolux Instrument Configurator color-codes
these values. Measurements can be trusted when QoS is green.
Measurements may be inaccurate when the indicator is yellow or red.
CSUM:
The check sum of the characters in the report from $ to * excluding these
characters.
Quality of signal color codes:
Green
– Excellent measurement quality
Green
– Good measurement quality
Yellow
– Low measurement quality
Red
– Unacceptable measurement quality

7.2. Servicing Protocol (RS-232)
The servicing protocol is used to retrieve and modify device operating parameters. Various device
settings, such as unit system and filtering parameters are configured using this protocol. Since
NMEA protocol is one way (it only outputs the data), the servicing protocol is always active.
To make radar configuration easy, Geolux provides the Geolux Instrument Configurator utility
application. Regular users do not need to be concerned about the servicing protocol used between
the Geolux Instrument Configurator and the surface velocity radar device. Geolux Instrument
Configurator is described in the Chapter 7 of this manual.
The servicing protocol listens on RS-232 serial port for incoming requests, and on each received
request, it will answer back.
The following requests are recognized by the servicing protocol and every command should be
followed by <CL>, <LF> or <CR><LF> (enter):
Change interface parameters
Baud rate
- Configures the baud rate (bits per second) for serial communication on both RS-232
and RS-485 data lines. This setting controls how many bits are sent on the communication line in
one second. The available values are standardized. Using higher baud rate over longer lines may
introduce errors in transferred data. The default instrument baud rate is 9600 bps.
RS-232 protocol
- Selects the communication protocol to be used for data communication on
RS-232 interface. The NMEA protocol is a GPS-like human readable messaging protocol where
each data packet contains a checksum for data integrity verification. SDI-12 protocol is used for
interfacing older type of Geolux SDI-12 adapters. Unless the instrument is connected to an older
Geolux SDI-12 adapter, NMEA protocol must be selected.
