MPPT Controller ve.direct over rs232 connection to router

I am trying to get the ve.Text mode to work, for passing the data which my SmartSolar MPPT 75/10 is sending out into a Rut956 Teltonika Router.

We using a UART for the signal conversion but the data we capture in Putty is not readable. We use baud rate 1200/8/1/none settings.

Any help is appreciated
