This
device allows a point-to-point (or point-to-multipoint) wireless connection
between two or more RS232/485 devices, in completely transparent mode.
This is a VHF 500mW erp device operating in the frequencies
from 169.4 to 169.475MHz conforming to the european decision 2005/928/CE,
and, for this reason suitable for free use within several
applications (Meter reading systems, tracing and Asset tracking
systems).
The coverage is about 12-15 km outdoor
line of sight. It's
possible to extend it, conforming to the standard, using a third device configured
as Digipeater or using a 3 elements Yagi antenna instead of the 1/4
lambda stylus or the dipole antenna.
The device is engineered into an anodized aluminium enclosure,
suitable, through a special accessory, to DIN rail mounting.
