Product overview
The CroSkylink C21D-100 provides broadband access and data transmission through a flat system architecture supporting point-to-point links, point-to-multipoint star networks and Mesh networks. Its bandwidth options are 1.4MHz/3MHz/5MHz/10MHz/20MHz/40MHz, with customizable 600M/1.4G frequency support and automatic power and frequency control. Transmission range is up to 100km in a star network and up to 50km in a MESH network. Equipment interfaces comprise one Ethernet port, two serial ports with RS232 as the default, and one USB 2.0 port.
Integration requires a 16V~27V supply, with maximum power consumption of 27±5W. The transmitter must have an antenna connected, antennas belonging to the same module must remain more than 0.2m apart, and receiving-port input must not exceed 10dBm. Continuous operation requires proper heat dissipation. Operating temperature is -20℃～+55℃, storage temperature is -40℃～+85℃, and humidity is 5%～95% RH. Custom frequency configurations require manufacturer customization and cannot be changed by users. Power ratings are inconsistent: the technical specification gives 33±5dBm maximum, the feature rating is 33dBm, and the description states up to 46dBm.
