6.2. 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 a Configurator utility
application. Regular users do not need to be concerned about the servicing protocol used
between the Configurator utility and the level meter device. The Configurator utility 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:
Change serial number
#set_serial_number=<>

Change serial baud rate
#set_baud_rate=9600
#set_baud_rate=38400
#set_baud_rate=57600
#set_baud_rate=115200
