1. RipEX – Radio router

1.1. Introduction

RipEX is a best-in-class radio modem, not only in terms of data transfer speed. This Software Defined Radio with Linux OS has been designed with attention to detail, performance and quality. All relevant state-of-the-art concepts have been carefully implemented.

RipEX provides 24×7 reliable service for mission-critical applications like SCADA & Telemetry for Utilities, SmartGrid power networks or transaction networks connecting lottery terminals, POS or ATM’s.

Any unit can serve as the central master, repeater, remote terminal, or all of these simultaneously, with a configuration interface easily accessible from a web browser.

Anybody with even basic knowledge of IP networking can set up a RipEX within a matter of minutes and maintain the network quite easily.

1.2. Key Features

  • Exceptional data speeds on the radio channel
    – >200 kbps / 50 kHz, >100 kbps / 25 kHz, >50 kbps / 12.5 kHz, >25 kbps / 6.25 kHz

  • 1× ETH, 2× COM, 1× USB, 5× virtual COM
    – Simultaneously on radio channel. COM1-RS232, COM2-RS232 or RS485, software configurable. Virtual COM ports over ETH controlled by Terminal servers. USB for independent service access via USB/ETH adapter and for automatic FW and SW keys upgrade.

  • Wifi management
    – Any smart phone, tablet or notebook can be used as a RipEX portable display.

  • 135–174; 215–240; 300–360; 368–512; 928–960 MHz
    – Licensed radio bands
    – Software-selectable channel spacing 50, 25, 12.5 or 6.25 kHz

  • 10 watts
    – Transmission output control, nine stages from 0.1 to 10 W. Hence QAM modulations (the highest data speed) require a very linear RF power amplifier, max. 2 W is available for them.

  • Energy saving
    – Sleep mode – 0.1 W, controlled via a digital input.
    – Save mode – 2 W, wakes up by receiving a packet from the Radio channel

  • Extended temperature range
    −40 to +70 ºC

  • Easy to configure and maintain
    – Web interface,
    – Wizards,
    – On-line help,
    – Balloon tips,
    – Fastest web access to remote units

  • Fast remote access
    – Only the effective data are transferred from remote RipEX over the air, html page is downloaded from the local unit.

  • Bridge or Router
    RipEX is a device with native IP support which can be set as a standard bridge or router.

  • Modbus, IEC101, DNP3, PR2000, Siemens 3964(R), Comli, RP570, C24, DF1, Profibus, SLIP, Async Link, Cactus, ITT Flygt, RDS, UNI, Modbus TCP, IEC104, DNP3 TCP etc.
    – Unique implementation of industrial protocols enables a secure addressed transmission of all packets in all directions

  • Three protocols on Radio channel
    – Fully Transparent (Bridge)
    – Flexible (Router) – for meshing networks providing unlimited footprint coverage without base stations
    – Base driven (Router) – optimized for TCP/IP applications like IEC104 making them reliable and stable even with a high number of RTUs.

  • Nomadic mode
    – Nomadic mode is a method of building a network that offers easy addition of a new ‘Nomadic Remote’ station to the radio network or easy transfer of ‘Nomadic Remote’ stations within the network coverage of ‘Nomadic Base’ stations.

  • Backup routes
    – When tested path between two RipEX IP addresses (even behind repeater or LAN) fails, automatic switch-over to backup gateway behind Radio or Ethernet interfaces
    – Unlimited number of prioritized backup gateways
    – Instructional video

  • VPN
    – IPsec is a network protocol suite that authenticates and encrypts the packets of data sent over a network.
    – GRE is a tunneling protocol that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links over an Internet Protocol network.

  • QoS
    – Quality of Service (QoS) is an advanced feature that allows the user to prioritize certain types of traffic stream over the Radio interface. Used to manage transmission of different traffic streams.

  • NAT
    – Network address translation, also referred to as NAPT (Network Address and Port Translation) is a technique in which private Internet Protocol (IP) addresses and port numbers are mapped from multiple internal hosts to one public IP address. Source NAT (SNAT) and Destination NAT (DNAT) were implemented. Ideal when all RTU’s have the same IP address.

  • Optimization
    – 3× higher throughput
    – Optimization method which joins short packets, compresses data, optimises both the traffic to the link peer and the sharing of the radio channel capacity among the links.

  • TCP proxy
    – Eliminates a transfer of TCP overhead over Radio channel when TCP overhead run locally between connected device and RipEX on LAN. I.e. only payload (user) data are transferred further as UDP (over Radio channel)
    – Higher RipEX network bandwidth, no more problems with TCP timeouts
    – Instructional video

  • ARP proxy
    RipEX can simulate any IP address (it may reply to any ARP request)
    – This feature is typically used when RTU addresses behind different RipEX units are within the same IP subnet and RTUs do not provide routing capabilities (neither default GW)
    – Instructional video

  • VLAN & Subnets
    RipEX can simulate any IP address (it may reply to any ARP request)
    – Unlimited number of virtual Ethernet interfaces (IP aliases) can be set

  • Embedded diagnostic & NMS
    – Real time and historical (20 periods, e.g. days) statistics and graphs for the unit and its neighbours.
    – SNMP including generation of Notification alarms when preset thresholds are exceeded
    – on-line/off-line (recorded to a file in the RipEX) monitoring of all interfaces

  • Security
    – 256 AES encryption, the most secure encryption meets FIPS 140 2 requirements
    – 2048 (1024, 512) bit SSL certificate (even your own one) for https web configuration

  • SW feature keys
    Software authorization keys allow you to add advanced features when needed: Router mode, 166/83 (The two highest Data rates for 25 and 50 kHz channel spacing), COM2, 10 W, Backup routes
    – Free Master-key trial – (all coded features) for 30 days in every RipEX

  • Reliability
    – 3 years warranty, rugged die cast aluminium case, military or industrial components
    – Every single unit tested in a climatic chamber as well as in real traffic

  • RipEX – HS
    – Redundant Hot Standby chassis
    – Two Hot Standby standard RipEX units inside
    – Automatic switchover capability on detection of failure
    – Suitable for Central sites, Repeaters or Important remote sites where no single point of failure is required

  • Internal calendar time
    – Can be set manually or synchronized via NTP (Network Time Protocol)
    – Any RipEX also runs as a NTP server automatically
    – NTP synchronization via Ethernet or over the Radio channel from another RipEX or from the built-in GPS
    – Powered from internal long life Lithium Manganese battery, so it is accurate even when RipEX is powered off

  • Flash memory
    – All configuration parameters are saved in flash memory

  • External Flash disc
    – Automatic firmware upgrade, SW keys upload, configuration backup/restore, ssl certificate and ssh keys upload and configuration, tech-support package download
