mLine 1:
Line 1: − + − + + + − + − + − The mode supports up to five LLS fuel level sensors. Baud rate must be 19200. LLS have receiver id. LLS mode configuration shown in Figure 69.+ − + − TCP Binary mode is the same as above but binary messages will be accepted.

RS-485 supports only Half Duplex communication. It means that at one time data is only sent/received.<br/>When activated RS-485 driver chip draws constant 30mA current.<br/>When Entering Sleep or Deep sleep, Chip will be powered off too.<br/>FMB125 RS-485 Pins connection diagram are shown on the Figure 66:
RS-485 supports only half-duplex communication, which means data is transferred only one way at a time.<br/>When activated RS-485 driver chip draws constant 30mA current, when entering Sleep or Deep sleep, RS-485 will be powered off.<br/>FMB125 RS-485 connection diagram is shown below:

===RS-485 modes===
* RS-485 transmit (FMB log) mode:
* RS-485 transmit (FMB log) mode:
RS-485 works in transmit mode, it prints FM log. It won’t respond to commands.
RS-485 prints FMB device log and does not respond to commands.
* RS-485 transmit (GNSS NMEA) mode:
* RS-485 transmit (GNSS NMEA) mode:
RS-485 works in transmit mode, it prints GNSS NMEA log. It won’t respond to commands.
RS-485 prints GNSS NMEA log and does not respond to commands.
* RS-485 receive (LLS) mode:
* RS-485 receive (LLS) mode:
This mode supports up to five LLS fuel level sensors each of which has a receiver ID.
* RS-485 TCP (ASCII/Binary) modes:
* RS-485 TCP (ASCII/Binary) modes:
In TCP ASCII mode link with external device using text messages can be established.
In TCP ASCII/Binary mode a link with external an device using text messages can be established.
