Telephus Viper SC data modem

The Viper SC is a secure, long-range, serial or IP data modem for SCADA, telemetry and other critical applications.

It is no longer necessary to choose between ethernet IP and long-range narrowband radio communications.

The radio modems deliver up to 48 Kbps IP over long-range licensed channels allowing secure user data brought from the field, right to the radio on the company LAN.

The modem is available in both VHF and UHF models with wide frequency ranges and programmable bandwidth (12.5, 25 and 50 kHz), minimising the number of models required to support a system. Security choices are extensive including encryption, VPN tunnelling and radius user plus device authentication.

It is a complete IP radio with layer 3 routing, NAT, DHCP, a full SNMP implementation and compression (header and payload). Connectivity options include serial, terminal serving, IP (TCP/UDP) and configurable store and forward. It is available in a range of models - remote, remote with dual RF port, standard base station or redundant base station.

Up to three speeds can operate concurrently in any one network. Sites with strong signal strength can use the fast speed, typical paths will support the mid speed and weaker paths that may have otherwise needed store and forward can use the lowest speed.
