S2: The standard deviation of water level measurements. The number of samples used
to calculate the standard deviation is equal to the configured filter length. This
parameter is available on units with firmware versions greater than 2.3.2.
7.2.2 TILT ANGLE REPORT
$ANG,A1,A2 <CR><LF> firmware versions greater than 2.3.5
$ANG: The keyword sent in the beginning of each angle report.
A1: The tilt angle of the instrument along X axis. For proper operation of the instrument,
ensure that this angle is zero, or as close to zero as possible (between -1 and +1
degrees).
A2: The tilt angle of the instrument along Y axis. For proper operation of the instrument
ensure that this angle is zero, or as close to zero as possible (between -1 and +1
degrees).
7.3 SERVICING PROTOCOL (RS-232)
The servicing protocol is used to retrieve and modify the instrument’s operating parameters. Various
instrument 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.
Easy radar configuration can also be done using the Instrument Configurator as described in
Chapter 8.
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 <CR>, <LF> or <CR><LF> (enter):
7.3.1 CHANGE INTERFACE PARAMETERS:
RS-232 baud rate: Configures the baud rate (bits per second) for serial communication on RS-232
data line. This setting controls how many bits are sent on the communication line in one
second. The available values are standardised. Using higher baud rate over longer lines may
introduce errors in transferred data. The default instrument RS-232 baud rate is 115200 bps.
#set_baud_rate = 9600
#set_baud_rate = 38400
#set_baud_rate = 57600
#set_baud_rate = 115200
#set_baud_rate = 19200
RS-485 baud rate: Configures the baud rate (bits per second) for serial communication on RS-485
data line. This setting controls how many bits are sent on the communication line in one
