Description Specifications AEV RDS Evo RDS Encoder The RDS Evo is also fully equipped with an RDS signal decoder; through this section it is possible to decode the data of an external RDS signal, decide which ones to keep and which to modify locally, and then regenerate the RDS data package to be supplied to the local FM transmitter. The RDS Decoder also allows the PI code contained in the external RDS signal to be monitored, if the PI code is different from the one programmed, it is possible to activate the exchange from the external MPX signal and the internally generated one. The GPO port takes the status of the machine’s inputs to the outside, for a simple interface with the transmitters’s telemetry. The machine can be controlled via ethernet thanks to the internal web server, this solution frees the user from installing PC software; in addition, the Web Server can be set as CLIENT, in case of insertion in a LAN network, or as a SERVER, if you want to directly connect a PC with an Ethernet network cable. It is possible to activate a password that limits access to the machine, inhibiting the modification of the setup parameters to unauthorized personnel. RDS GENERATOR: RDS signal: Standard specif.
