==RS-232 / RS-485 interface==
RS-485 supports only full-duplex communication, which means the data can be sent and also received at the same time.<br/>
RS-232 supports only full-duplex communication, which means the data can be sent and also received at the same time.<br/>
'''Note:''' In RS-232 LLS mode can be connected only one LLS fuel level sensor.<br/><br/>

====TCP (ASCII/Binary) modes====
In ''TCP Ascii/Binary'' mode all data received from the external device is sent directly to the server. Data is encapsulated in codec 12 format. ''TCP Binary'' Mode has a delay of 30 ms, if no data is received for 30 ms, data is sent to the server. ''TCP Ascii'' mode waits for the End of Line (EOL) character (0x0D0A, \r\n, <CR><LF>) to pack data and send it to the server.

''TCP Ascii'' mode waits for the End of Line (EOL) character (0x0D0A, \r\n, <CR><LF>) to pack data and send it to the server.
''TCP Ascii Buffered'' and ''TCP Binary Buffered'' modes are used to collect data from RS232 and save it in the buffer if there is no link with the server and data cannot be sent immediately. When the link is established and there is data to transmit, then RS232 data from the buffer is transmitted after all records are sent. Data is sent in codec 13 protocol. Note, that in ''TCP Ascii'' and ''TCP Binary'' modes device sends data from the external device only to the main server. In Buffered modes – to both main and backup/duplicate servers.

In this mode, the user is able to communicate with the server through the terminal. A link between the FMB device and the server has to be established for this mode to function properly.

To communicate from terminal to server - in terminal send command "WT^W your text here"
