Product overview
The CroSkylink C21D-150 provides broadband access and data transmission using a flat system architecture. It supports point-to-point links, point-to-multipoint star networks and Mesh networks, with automatic power and frequency control. Bandwidth options are 1.4MHz/3MHz/5MHz/10MHz/20MHz/40MHz, alongside customizable 600M/1.4G frequency options. Other frequency bands can also be customized according to customer requirements and the installation environment; users cannot change these themselves. Equipment connections comprise one Ethernet port, two serial ports with RS232 as the default configuration, and one USB 2.0 port.
Transmission distances extend up to 150km in star networks and up to 100km in MESH networks. The typical application configuration uses point-to-point communication, dual antennas, a 1437MHz working band, 20M bandwidth, maximum transmit power and rated-voltage supply, at 25℃ and 50% humidity. The electrical requirements are 24V~27V operating voltage and 60±12W maximum power consumption. Power ratings comprise a technical specification of 40±3dBm maximum, a 40dBm maximum output feature rating and a descriptive maximum transmission rating of 46dBm.
Installation requires antenna spacing greater than 0.2m within the same module and greater than 1m between modules, applying to both powered-on and powered-off modules. Antennas must be connected correctly: improper connections can damage the device or cause serious performance differences. Continuous operation requires proper heat dissipation, and receiving-port signal strength must remain below 10dBm. The operating temperature range is -20℃ to +55℃, the storage temperature range is -40℃ to +85℃, and the humidity range is 5% to 95% RH.
