Hello, Dear sagi,

Thank you for question.

It depends which I/O elements you choose in I/O settings like in picture below.

If you choose Low, High or Panic priorities near I/O element which are marked red rectangle, you will get this element to your server in AVL data packet.

More information about I/O elements: https://wiki.teltonika.lt/view/I/O_settings

Please feel free to ask us if you will have more questions or if we misunderstood your situation.

Best wishes,

The thing is that I need to understand what does each data relate to and what are the values mean

Thank you for explanation.

To send AVL data packet to the server there are three types of protocols:

• Codec 8
• Codec 8 Extended
• Codec 16

In short, Codec 8 is our base firmware which is using to send parameters which AVL ID is up to 255. Codec 8 Extended is supported in FMB, FMC, FMM and FMU family devices and it looks similar like Codec 8 but the main difference is that with this protocol you can additionally send parameters which AVL IDs are higher that 255 and which value size is over than 8 bytes (for example, VIN parameter in OBD II settings). Codec 16 is supported only in FMB630/FM63XY devices and is using when AVL IDs are higher that 255. There are also two modes how the data packet is sending - TCP and UDP but there is not important which one of them you will be use.

Below I attached Codec 8 AVL data packet in TCP mode and table where you will see how it is parsed with meanings:

The similar are parsing Codec 8 Extended and Codec16 protocols in TCP and UDP modes.

More differences between mentioned protocols you can see in the table below:

If you want to know AVL ID meaning, you can always check in our Wiki page: https://wiki.teltonika.lt/view/FMB_AVL_ID

More information about mentioned Codec protocols you can find here: https://wiki.teltonika.lt/view/Codec

Please let us know if something was unclear or you will have more questions.

Best regards,

Well, I think that the answer that I'm looking for will not be in the wiki.

for example, I'm trying to look for the PDOP data that is been sent to the GPS-SERVER, I can't find any explanation about that string.

another example, let's take the RSSI data package that is been sent to the GPS-SERVERS, the values are "integer" , I guess between 1 to 5 or 6, but I don't have any documentation about what are those numbers represent.

This is the data log that my GPS-SERVER is getting from the FMB920 tracker, How can i understand the meaning of each data?

Hi, sagi.

Crowd-support has provided the link that you need - https://wiki.teltonika.lt/view/FMB_AVL_ID. On that page please check contents of column Description. It's the most complete description of IO parameters among the information published by Teltonika. At first glance it's not very comprehensive, but that's enough in most cases.
Please note, that your GPS_SERVER can modify data incoming from device. E.g. device sends "GSM Signal" which  represent quality of signal in relative levels (from 1 to 5, you were right), but your server calls it RSSI, so maybe it applies a coefficient to GSM Signal to convert it to dB (RSSI is usually measured in dB).
