Expansion board with RS232 data interface to connect a radio interface card for digital radio type IF 90-FUVER-D/40-FUVER-D to the digital radio in order to be able to exchange information in both directions that is only available in digital radio.
The interface is electrically isolated and has no intelligence of its own, meaning that only data that can be analysed in the IF 90-FUVER-D/40-FUVER-D radio interface card can be transmitted. This depends on the respective radio device type.
