Product overview

The CroSkylink C33S-100 combines Ethernet and serial data connections in a 100×60×30mm unit weighing approximately 235g. Its interface complement comprises one Ethernet connection, two RS232 connections and one TTL serial connection. These dimensions and connections define the physical space and data interfaces available for integration. Power consumption spans 6~20W, with operation specified from -40 to +65°C. Transmission latency is approximately 7ms, while the available encryption choices are DES, AES128 and AES256.

The radio operates across 500~680MHz or 1300~1500MHz with frequency adjustment in 1MHz increments; a customizable 70~6000MHz range is also offered. Transmit power is 36dBm, expressed as 4W from 2×2W, and adjusts in 1dBm steps. Network scale is 64 nodes, with 128 and 256 nodes optional. Bandwidth modes are 1.25, 2.5, 5 and 10MHz, with optional 20, 30 and 40MHz configurations. The 220+ Mbps peak rate requires 40MHz bandwidth, and the 100+ km communication range requires line of sight. Adaptive frequency selection and wideband frequency hopping are optional.
