MR400 Radio Modem
MR400 is awell proven radio modem, on the market for over a decade and undisputably well established. Tens of thousands units serve reliably around the world, fromthe poles to the equator.
MR400 uses a sophisticated anti-collision protocol on the Radio channel. Its unbeatable network performance is boosted by the unique implementaion of proprietary SCADA protocols fromall significant vendors on the SCADA market.
Thanks to MR400 extraordinary intelligence, speed and switching time, they are suitable for all types of networks where emphasis is placed on speed and reliability, such as SCADA & Telemetry for utility distributions (water, electricity, oil&gas), SmartGrid power networks, Transaction networks like lottery, ATM or POS, mobile networks including mission critical fleet management and many other applications.

- Polling, Report-by-exception, Mesh Throughput limits for 22 kbps/25 kHz:
- 600 Bytes/sec. in collision environment of all units within one radio coverage area
- 10 packets/sec. (for packets shorter than 60 Bytes)
- 15 kbps user data rate for point-to-point link
User protocols
- More than 70 protocols - Modbus, IEC101, DNP3, Comli, DF1, Profibus, Modbus TCP, IEC104….
- Cache mode - speeds up polling protocols
- SCADA serial protocol addresses are mapped to MR400 addresses
- TCP (UDP) protocols (e.g. IEC104) are handled transparently
- Each packet is acknowledged on Radio channel
- Sophisticated anti-collision protocol on Radio channel => report by exception from remotes, simultaneous multi master polling
Ultimate OS
- No Linux
- No Windows
- Extremely fast booting (3 sec.)
Modular
- 5 slots for modules:
- Ethernet, GPS, M-BUS
- 2x RS232, 1x RS232, 1x RS232i, 1x RS422/485i,

Coverage
- 70, 160, 300, 400 MHz bands, no direct line of sight required
- Carrier output power 0,1-5 W or 0,1-25 W
- Exceptional data sensitivity: -105 dBm / 22 kbps / 25 kHz
- Max. distance more than 50 km
- High resistance to multi path propagation and interference (CPFSK modulation)
- Every can work simultaneously as a repeater
- Hybrid networks: - any IP network (Internet,3G/GPRS etc.) can interconnect MR400 units
- Unlimited number of radio hops
Mobile network
- Connection-less Mobile mode in Radio protocol
- Every stationary unit can serve simultaneously as a Base station for mobiles Cell architecture: automatic instant hand-over, each individual packet from mobile is delivered via the best Base station at the moment
- Central MR400 maintains a list of “mobile-base” connections, updated with every packet, to enable communication from the centre to mobiles
Fast to configure and diagnose
- Setr - special Windows or Linux application for configuration
- The fastest and most robust remote access with minimum data over the network
- Monitoring of User interfaces and Radio channel, either locally or remotely
- On line as well as historical statistics for all interfaces and Radio channel
RANEC - Network Management
- Collects statistics from all units and save them in database Extra load generated by RANEC is automatically regulated based on user traffic
- One server + unlimited number of graphical clients Possible to display all statistics in graphs
- Displays the network topology on a background map Network planning - it calculates the coverage using digital model of the terrain
Security
- Licensed radio bands
- FEC, interleaving, proprietary data compression
- CRC32 data integrity control on Radio channel Proprietary protocol on Radio channel with packet acknowledgement
- Blowfish 160 encryption
- Netlock - application which enables/disables remote access to the unit for three level of users
Reliability
- Every single unit tested in a climatic chamber as well as in real traffic
- Military or industrial grade components are used
- Industrial die cast aluminum case
- -30°C to 70°C (-22°F to +158°F)
Energy savings
- Sleep mode - 2.5 mA, controlled via a digital input
- Power down - unit boots within 3 sec. after power up
Other Highlights
- DIN rail, flat or 19” rack mounting
- CE, FCC approvals
- Vibration - EN 61 373
