Hello,

I'm sorry for the first post without picture...

For my cousin I try to connect a trimble FMX with an NTRIP network.

Our system:

Ntrip client is install on a raspberry PI B(RPI) it's : POSIX ntripclient.

It was developed by BKG (a german governement agency who designed NRIP protocol ).

We use a cellular with USB cable to connect the RPI to internet.

The NTRIP Network is Centipede .

We supply the RPI by FMX USB port.

RPI is connect to fmx by a USB/serial adaptator and serial cable cabling like that:

Today we remove the internal radio, to evite some perturbation with it.

FMX config:

Here, I have my firsts Questions:

• Were is the firmware version?

• Is it a compatible version to receive RTCM on D port ?

• This is an unlocked RTK or not?

In setup screen we select centerpoint RTK:

I have this error,it's normal I remove the internal radio:

"please configure External radio by ag remote"

In Agremote, I selected:

• RTK source

• Port D : Input RTCM 9600,Output none 9600

We can see I havn't any Corrections.

I look port D diagnostics, I see:

It's seem good.

I suppose I forget something somewhere, but I don't know what.

You're very welcome for your help, thank you.
