ZK300S is an open network modem, the data rate is divided into 3 bands to choose from: low rate (128kbps -5Mbps), medium rate (2Mbps -10Mbps), high rate (2Mbps - 50Mbps). STANDARD RJ45 INTERFACE, EIA422, EIA232 interface are also provided, built-in gateway function, and QOS guarantee is provided. The device can also choose audio codec function, the rate is 2.4Kbps or 8Kbps; Optional video codec function, support H.264 standard, variable rate, interface support CVBS or VGA, expandable to HDMI. The architecture of the ZK300S is based on firmware and programmable gate array (FPGA), and the internal flash memory can be easily updated through the debug port or remotely.
The modem integrates the BUC/LNB power supply and 10MHz reference options, providing a 10MHz reference to the transmitting BUC directly through the Tx feeder, and at the same time supplying the LNB through the Rx feeder, thus greatly simplifying the system structure, increasing reliability, and reducing the amount of on-site construction.
