====RS-485 receive (FMB silent) mode====
====RS-485 receive (FMB silent) mode====
RS485 Works in receive mode. Support debug and testing commands. When the command is received answer is sent after that it back up to Receive mode.<br/>

====RS-485 receive (LLS) mode====
====RS-485 receive (LLS) mode====
This mode supports up to five [[{{{model|FMB640}}}_RS-232_and_RS-485#LLS_Sensor|LLS fuel level sensors]] each of which has a receiver ID.<br/>

====RS-485 TCP receive (ASCII/Binary) modes====
====RS-485 TCP receive (ASCII/Binary) modes====
In TCP ASCII/Binary mode a link with an external device using text messages can be established. Buffered modes save the information until a link with the server is established and records are sent.

====RS-485 receive (TCP ASCII/Binary Buffered) mode====
====RS-485 receive (TCP ASCII/Binary Buffered) mode====
RS485 works in receive mode. When data received from server RS485 is switched to transmit mode. If the data server is not available, data will be saved in the buffer.

===RS-232 modes===
------------------
Silent, Log mode, NMEA, LLS, TCP ASCII, and TCP Binary modes, TCP ASCII/Binary Buffered modes are identical to those of [[{{{model|FMB640}}}]] RS-232 and RS-485 modes.<br/>
