Industrial Frequency Hopping 900 MHz Serial (FCC), RLX-IFH9S-A

Type:  Modem
Description:  The RLX-IFH9S provides powerful, secure wireless serial communications and is well suited for demanding, long-range (up to 30+ miles) SCADA and other serial applications in tough environments. Operating in the license-free 900 MHz band, the RLX-IFH9S penetrates foliage and walls/ceilings better than higher frequency radios. With both RS-232 and RS-485 serial ports, serial protocols such as Modbus RTU, DF1, ASCII and DNP3 are supported. The RLX-IFH9S is user configurable as a master, repeater and remote radio and employs the 128 bit AES encryption algorithm approved by the US government for top secret information.
Connectivity:  Modbus
Features:  Powerful 900 MHz Serial 230 kbps RF data rate at up to 30+ miles; Longer wavelength of the unlicensed 900 MHz band for superior wireless signal propagation vs. higher frequency unlicensed wireless bands; Rugged and Powerful Up to one watt transmit power for long-distance; Programmable frequencies to co-exist with other wireless networks or avoid interference; Metal enclosure, industrial operating temps; Vibration and shock resistant; Certification pending for use in hazardous locations (UL1604 /ISA 12.12.01 Class I Div 2); Strong Data and Network Security 128 bit AES Encryption; Proprietary FHSS not detected by 802.11 wireless; Easy to Configure and Monitor Graphical representation of network for configuration and diagnostics; Advanced diagnostics including VSWR, temperature, and signal quality; OPC Server included for HMI-based RF network diagnostics
Specifications:  Frequency 902-928 MHz; Security 128 bit AES encryption; Network Topology Point-to-point, point-to-multipoint, store and forward repeater; Error Detection 32 bit CRC, ARQ (Automatic Resend Query); Radio Type: Frequency Hopping Spread Spectrum; Transmit Power (Programmable) 100 mW to 1 W, 20 dBm to 30 dBm; Channel data rates (Programmable) 230, 172, 115 or 19.2 kbps; Receiver Sensitivity (Typical) 230 kbps: -106 dBm @ 10-6 BER, 172 kbps: -108 dBm @ 10-6 BER, 19.2 kbps: -116 dBm @ 10-6 BER; Outdoor Range 30+ miles pt-pt with high gain directional antennas and RF line-of-sight
