RE400 Transparent Radio Modem
RE400 works as a standard IP network bridge, i.e. it is fully transparent. Every unit can serve as the central master or as a remote terminal and it can also simultaneously operate as a repeater.
The modern digital solution of the radio part (Software Defined Radio) of the RE400 radio modem allows for a wide frequency range a SW configurable channel spacing.
- 400 MHz
- 6.25, 12.5, 25 kHz
- 11 kbps / 25 kHz
- 2W
- 1x ETH, 1x RS232
- PoE or 10 – 30 V DC
- Transparent bridge
- Plug and play
Applications
- Polling type networks
- Water
- Oil & Gas
- Electricity
- Smart grid POS &ATM
- Lottery
- Weather
Fully transparent
- Standard IP network bridge functionality is implemented in the RE400 radio modem, i.e. the ETH interfaces of all the radiomodems in a network are interconnected according to bridge principles.
- When a COM interface is used, every frame received over a COM is simply broadcast to COM interfaces of all units in the network.
Easy to configure and maintain
- Web interface
- All configuration parameters within one page
- Basic IP knowledge is sufficient
- CLI via SSH
Security
- Licensed radio bands
- FEC, interleaving, proprietary data compression
- CRC32 data integrity control on Radio channel
- Password-protected access, https web interface
Coverage
- 400 MHz band
- Line ofsight is not required
- Carrier output power adjustable 0,5 or 2W
- Exceptional data sensitivity
- High resistance to multipath propagation and interference
- Any unit can work simultaneously as a repeater
Reliability
- Every single unit tested in a climatic chamber as well as in real traffic
- Military or industrial components
- Industrial rugged die-cast aluminum case
Others
- Local and remote diagnostics
- DIN rail mounting
- L-bracket, flat-bracket, direct mounting
