FMB641 and TachoGraph

I am going to start the work with Tachographs. I am having FMB641 Teltonika device. I am going to download the Tachograph data remotely for which i am doing this wiring (Image Attached). Is it necessary to Connect FMS connection also for downloading Tachograph data ? OR we can get all the Tachograph information and able to download the Tachographs information with this wiring


Good day, please visit our wiki pages for the tachographs .
