Iridium Edge
Iridium Edge features an all-in-one SBD module and antenna, with power supply. The plug-and-play satellite IoT terminal can be easily paired with FMB devices in order to expand their functionality to no GSM coverage zones. Current Iridium implementation offers ability to generate and send SBD records after set period after the GSM signal is lost. This ensures constant connectivity for the clients as Iridium network is available globally.

Configuration
FMB Firmware implementation on FMC125
In order to enable Iridium support on FMB, first it is necessary to enable RS232 support and select “satellite backup” mode. Correct configuration is shown in the picture below.
Next, there are a couple of configurable options. In the SBD config, IridiumEdge should be enabled and save/send period Set. This section can be found in the “Features” tab in the configurator.
Setting up Alarm priority records
NOTE: In addition, you can select which IO element can generate Alarm priority record. The configurable IO parameters are listed as SBD IO source in list above. In order to do that you need to configure these IO elements as Panic priority. If properly configured SBD records are generated and sent if there is no GSM connection.
In the scenario shown in the above picture when panic record is made (generated by Digital Input 1 or Digital Input 2) internal 90 seconds timer will start to tick and if in that timeout device will not send the record through GPRS network it will be sent with Iridium satellites.
SBD Upload Limit is configurable and resets every month. This option can ensure that no additional data is used so that no unexpected costs are experienced by the customer. Default value is 8000 (for 8KB plan). This option can be disabled by setting Upload limit to 0.
NOTE: SBD IO source functionality is still being implemented.
FMB Firmware configuration on FMX640/FMX641 devices
FMX640 can be setup with Iridium Edge by activating RS232 short burst data parameters, this can be done visiting this tutorial Here.
| PIN OUT Configuration | ||||
|---|---|---|---|---|
| Pin Number | Signal Name | Color | Signal Direction (With respect to iridium edge) | Description |
| 1 | Spare | White | - | Unused |
| 2 | Ground | Brown | Input | Signal and power GND |
| 3 | RS232_RX | Green | Input | RS232 input |
| 4 | RS232_TX | Yellow | Output | RS232 output |
| 5 | Power | Pink | Input | 9-32 V positive terminal |
| 6 | ON/OFF | Grey | Input | Optional line to power down Iridium edge |
| 7 | Network available | Blue | Output | - |
| 8 | Power detection | Red | Output | Active high when Iridium Edge is powered |
Important note: There is a noticeable difference in Iridium 8-pin cable layout from the standard version of the cable. We recommend purchasing a specific Iridium-made and certified 8-PIN cable directly from Teltonika. Please contact your administered sales representative to make an order.
Communication Protocol
| SBD Packet structure | ||||||
|---|---|---|---|---|---|---|
| Timestamp | Longitude | Latitude | SBD AVL ID and flags | DIN/DOUT info | Reserved | Speed |
| 4 bytes | 3 bytes | 3 bytes | 1 bytes | 1 bytes | 1 bytes | 1 bytes |
Definitions
- Timestamp – Indicates when record was generated
- Longitude - encoded in 3 bytes data. Server which gets this data should divide result from 46603,375 and subtract 180 in order to get actual longitude value. This coefficient is got in following way: 16777215(maximum 3 bytes value) divided from 360 (maximum longitude value then 180 is added). This calculation is used to fit negative and positive values to 3 bytes width variable.
- Latitude - Latitude is calculated in same way as longitude but since latitude maximum value is two times smaller than longitude it can produce a bit more accurate data. Coefficient for latitude is 93206,75. This coefficient is got in following way: 16777215(maximum 3 bytes value) divided from 180 (maximum latitude value then 90 is added). This calculation is used to fit negative and positive values to 3 bytes width variable.
- SBD AVL ID and flags – Custom id that will indicate what caused the record to be generated (as only periodic records are generated, id is not used)
- Din/Dout info - Displays configured IO elements in parameter id 99422
- Reserved - Not used anywhere, but left due to compatibility with fm6 project.
- Speed – Indicates the speed of the vehicle if configured. If not (or in case of no gps) – will display 255
Data Sending Parameters
Information here includes the data sending parameters which identifies the naming of the parameter in accordance to it's number.
| Parameter ID | Parameter name | Min values | Max values | Default values | Description |
|---|---|---|---|---|---|

| 99421 | Save/Send period | 0 | 1440 | 1440 | This parameter lets to configure Iridium Edge sending period |
| 99422 | SBD IO source | 0 | 6 | 0 | SBD IO elements which when enabled are included into the SBD record |
| 151 | RS232 Mode | 0 | 26 | 0 | Implement ability to select "Sattelite backup" |
| 99423 | SBD Upload Limit | 0 | 30000 | 8000 | Limit to save user from exceeding the monthly plan. Max limit of 30000 due to 30KB plan. If set to 0 – limit will be off. |

Please check available questions and answers to them here. If you are not able to find answer then fill the VIP HELP desk query.
| Question | Comments |
|---|---|
| Which Teltonika GPS trackers support Iridium Edge? | Teltonika FMC125 and FMX64x trackers support Iridium Edge currently. |
| With the FMX64 model, can CAN data be sent via Iridium data link? | CAN data be sent only using GSM link. Using Iridium data link you can send: Location, Speed, Ignition status, Panic button, DIN, DOUT, Crash detection (FMC125). |
| Can the data sending work for real-time monitoring? Or should it be scheduled for each x second/minutes reports? | No, it will start working when the connection is lost. |
| Does the device need to have certifications CE/FCC/PTCRB or any local ones? | Iridium Edge device certificates are to be found at https://www.iridium.com/products/iridium-edge/. Requirements for certification are decided by local governments. |
