Service IP: The IP Output Port address. The format is xxx.xxx.xxx.xxx (like as 192.168.2.137). Output IP: The IP Output data receive address. The format is xxx.xxx.xxx.xxx (like as 224.2.2.2). After set the Output IP address , you must use the new address to receive IP Output data. Subnet Mask: General is 255.255.255.0, it is must the same in a local area network. Gateway: If the device is in different net segment, you must set the gateway. Port: The UDP protocol port (like as 8001), you should use Output IP and new port to receive IP Output data (like as udp://224.2.2.2:8001). Note: The signal available at the IP Output is the same as the RF output. The protocol used for the MUX stream is UDP, so to see the modulated channels you need a program that has this protocol, like VLC Media Player. In recent versions of this particular program is necessary to put @ before the IP address, for example, “udp :/ / @ 224.2.2.2:1234”. Important: Not all computers have the ability to view a service provided by a 554803. Note: In the first use of the product, it is recommended to “Load Default” before starting with the configuration. 11) Reboot DVB-T Modulator 14 12) Firmware This function is used to upgrade the device’s latest software program.
