8.2. 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.
To make instrument 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 level meter device. Geolux Instrument Configurator is described
in the chapter 9 of this user 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 <CR>, <LF> or <CR><LF> (enter).
Change interfaces 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 rates 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
