Hello Vijay Karla,
Thank you for your inquiry.
We double checked firmware and Teltonika configurator versions for FMB208 and we see that you will need to update your firmware to the newer one. Then your mentioned configurator version will support your FMB208 unit.
We would like to inform you that we do not share firmware files / updater and other files in community forum. To receive firmware files, updater and documentation on devices, please contact your sales manager.
