* 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 data server is not available, data will be saved in buffer.
RS485 works in receive mode. When data received from server RS485 is switched to transmit mode. If data server is not available, data will be saved in buffer.
==RS-232 Interface==
RS-232 supports full-duplex communication which means the data can be both sent and received at the same time as they use separate transmission lines. Most of the modes are the same as for {{{model|FMB640}}}.
{{{model|FMB640}}} RS-232 connection diagram is shown on the figure below.

===RS-232 modes===
Silent, Log mode, NMEA, LLS, TCP ASCII and TCP Binary modes, TCP ASCII/Binary Buffered modes are identical to those of FMBXXX RS-232 and RS-485 modes. In RS-232 LLS mode only one LLS fuel level sensor can be connected.
* RS-232 LCD mode:
In this mode user is able to communicate with the server through terminal. A link between FMB device and the server has to be established for this mode to function properly.
* RS-232 RFID HID/RFID MF7 mode:
Radio-frequency identification (RFID) is the use of a wireless non-contact system that uses radio-frequency electromagnetic fields to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking. FMB640 can be configured in a way to use with an RFID reader. When an RFID of some sorts (typically a plastic card with a magnetic line) is used with an RFID reader which is connected to FMB640, the device creates a record with the data that the RFID reader has read and can be sent to a server with all other information. RFID ID is activated like an I/O parameter <br><br>
<br>

<br>
To set up FMB640 so it can be connected to an RFID reader, some parameters have to be set up. Go to RS232 \ RS485 and set up COM1 or COM2 settings to RFID Mode or RFID MF7 Mode (the used mode depends on the mode that the RFID reader works). See Figure 922. The Baudrates foreach mode are: <br><br>
RFID Mode – 57600<br>
RFID MF7 Mode – 9600<br>
<br>

<br>
The difference between ''RFID HID Mode'' and ''RFID MF7 Mode'' is that in ''RFID HID Mode'' {{{model|FMB640}}} understands RFID messages that are in hexadecimal format and ''RFID MF7 Mode'' interpretes messages that are in decimal format. The type of RFID message sent to {{{model|FMB640}}} depends on the RFID reader. For example, ''RFID HID'' mode message looks like "$aa$02$03$04$17$89$00$01" while ''MF7 mode'' message is of following format: "1213141519".<br/>The selected mode has to correspond to the RFID reader's mode.<br/>Please contact your local sales representative for more information about RFID IDs and devices.
* REC to LCD mode: In this mode records are sent via ports.
This is an example view that is displayed in Terminal :

* ATOL Tachograph mode: This mode is used to connect ATOL tachograph.
* UL202-2 Fuel Sensor: Select this mode to make Ultrasonic Fuel Sensors to work on COM port.
* Satellite Backup mode:
Since 00.02.05 firmware version device supports Iridium devices which can send short burst data (SBD) to server. This means that some data can be sent from FM device to server through satellites.
In order to get those records you have to connect device to FM64 COM1 or COM2 port. Select COM1 or COM2 mode Satellite backup mode. Those settings could be found in RS232/RS485 TAB in configurator. Baud rate for satellite devices is 19200 bps. Furthermore TSM232 functionality should be enabled. These settings can be found in Features TAB in Short burst data settings. See picture belowDevice supports Iridium devices which can send short burst data (SBD) to server. This means that some data can be sent from FM device to server through satellites.
* RS-232 Garmin mode:
Garmin provides a Fleet Management Interface Tool Kit, once {{{model|FMB640}}} is connected to the navigator it enables the driver to have a "screen" in their vehicle for real-time navigation and messaging, and offers job dispatch capabilities to help them be more efficient.<br/>{{{model|FMB640}}} and Garmin operational diagram is shown on the figure below.

Garmin configuration is shown on the figure below. <br>

==LLS SENSOR==
LLS sensor series liquid level sensors are solid-state capacitive devices with no moving parts. The sensors use capacitive technology to produce accurate liquid level measurements of standard factory grade DIESEL OIL and PURE GASOLINE (BENZINE) carbon fuels. The LLS sensor liquid level sensors are strictly prohibited to use in any liquids which are not the factory grade carbon fuels or contain: BIOFUEL, METHANOL, ETHANOL, UREA and similar aggressive components in pure form or as additives for factory grade carbon fuels for use in INTERNAL COMBUSTION ENGINES. Operating media – Diesel fuel (oil), pure gasoline (benzene). <br>
In order to use LLS fuel counter the newest firmware version is needed which can be obtained from Teltonika or a representative. Firmware is updated over GPRS or using cable update method. <br>
The LLS fuel sensor must be connected to the FMB640 device. <br>

Then FMB640 must be configured. Both fuel level and fuel temperature has to be set up by
configurator’s I/O menu: <br>
