Teltonika TSM232 is Iridium SATELLITE terminal with a backup battery. Full solution combines Teltonika TSM232 with Teltonika FM63XY, FMB630, FMB640 or FMB125 connected via RS232. This solution allows to transfer data to server via Iridium satellite network when other terrestrial networks are unavailable. High capacity internal Ni-MH battery ensures long autonomous working hours, when main power source is disconnected. Such solution meets the demand of high security logistic, marine transport, construction & mining transport, oil/gas industry, public safety, government/defense and more.

First Start Guide[edit]

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.


To access the iridium functionality you must have:

  • Firmware version: 00.03.03+
  • Hardware: RJ-45 Cable

TSM232 connection scheme[edit]

Port1/2 cable from FM package can be used for TSM232 connection. For this you need to cut a D-SUB connector and connect wires according instruction below.(PIN 4 to TSM GND, PIN5 to TSM Rx, PIN6 to TSM Tx).

At first FM63XY/FMB630 device will have default factory settings set. These settings should be changed according to the user's needs first. Please see our First start guide here.

After you have connected device to FM COM1 or COM2 port. Select COM1 or COM2 mode Satellite backup mode. Those settings are found in External devices TAB. Baud rate for satellite devices is 19200 bps

FM will enable satellite mode only if device can not send data via GPRS. Sattelite mode has his own Save/Send period. If timeout is set to 0 no periodic records will be made. It is not recommended to save records often because of satellites traffic price. 8 kilobytes monthly data limit is harcoded in firmware. If data limit is reached – data limit counter will reset automatically only on next month first day or you can rest counter by sms command “sbdlimitsreset”

In addition, you can select which IO element can generate Satellite record. In order to do that you need to go to IO tab select IO record priority Panic and check checkbox “Satellite I/O” what you want to get that data through satellites if there is no GSM connection.

In this scenario, then the Digital input record will be generated internal 90 seconds timer will start to tick and if in that timeout device will not send record through GPRS network it will be sent with Iridium satellites. Only 9 elements can generate Alarm priority records in the current firmware version. These elements are Digital input 1, Digital input 2, Digital input 3, Digital input 4, Digital output 1, Digital output 2, Digital output 3, Digital output4, Speed. Record which will be sent through Iridium satellites network will be different than the regular record. It will contain: 4 bytes timestamp, 3 bytes longitude, 3 bytes latitude, 1 byte record generation info, 1 byte DIN,DOUT info, 1 byte speed value.
