DATA INTERFACES
The LX-80 level meter offers multiple data interfaces, for ease of integration with existing
SCADA/telemetry systems.
6.1 SERIAL RS-232 INTERFACE
The Serial RS-232 interface is used for direct connection of a single level meter unit with the
computer. The serial interface is used both for retrieving live level measurements and for
configuration of the level meter device. Use the PC application, Instrument Configurator for
instrument configuration and level monitoring.
Default communication parameters are:
Bitrate: 115200 bps
Data bits: 8
Stop bits: 1
Parity: None
An NMEA-like communication protocol is used to deliver level measurements over the RS-232
interface. Detailed description of the protocol is given in Chapter 7 of this user manual.
6.2 SERIAL RS-485 INTERFACE
Serial RS-485 interface is used for connecting multiple level meters to a single data logger using a
single RS-485 bus. The main difference from the protocol used over RS-232 interface is that the level
measurements are not reported automatically but are instead reported only after being requested
by the master device (data logger unit). The LX-80 supports Modbus protocol over the RS-485 bus.
Detailed description of the protocol is given in Chapter 7 of this user manual.
Default communication parameters are:
Bitrate: 9600 bps
Data bits: 8
Stop bits: 1
Parity: Even
Device ID: 1
