| Series SRM6310E of Data-Linc Group |
Data-Linc
Group's license-free SRM6310E Ethernet Modem offers maximum reliability
and
performance for wireless
Ethernet transmission.
Using Smart Spectrum frequency
hopping technology in the 2.4 to 2.483 GHz frequency band,
the SRM6310E
provides reliable, robust communication with a rated range of up to 20
miles (32 km) and an installed range of up to 30 miles (48 km) with
line-of-sight (LOS).
The
SRM6310E ensures
reliable transmission using frequency hopping spread spectrum
technology and 32-bit CRC error correction. The RF data rate is 144
Kbps. Costly RF site surveys are typically unnecessary and an FCC
site license is not required.
Installation of the
SRM6310E is simple
and inexpensive. SRM6310E
wireless technology does not require hard wire or fiber cable, which
are often expensive and difficult to install.
The
SRM6310E
supports a number of configurations, including point-to-point and
multi-point. Multi-point operation permits an unlimited number of
remotes. The SRM6310E can also function as a repeater to extend range
or work around obstructions.
Industrial
Applications
The
SRM6310E is ideal for industrial automation systems with:
- PLCs located on moving
platforms, overhead cranes and turntables or other revolving
equipment
- Remote PLC
programming and diagnostics
-
SCADA systems, such as water/wastewater, utilities
and oil/gas systems
- Underground or
off-shore communications
-
High RFI
environments (e.g., steel, manufacturing)
