Wireless Operation
The LEX unit and REX unit wirelessly communicate over the IEEE
802.11g radio protocol at a distance up to 30 meters. The actual
communications distance will vary greatly depending on the amount and
type of physical obstacles and radio interference in your area. In
general, the WiRanger should have similar range to that of a normal
802.11g router or access point.
The LEX unit and REX unit of this WiRanger are “Paired” at the factory
so that they will only communicate with each other, even if other
WiRanger’s are installed near by.
NOTE: Under normal operating conditions, you should never need to
“Pair” the units. However, if absolutely required, the units
can be “Paired” using the procedure listed on Page 12,
Advanced Setup – Pairing a LEX unit and a REX unit.
The IEEE 802.11g standard allows for different wireless devices to
operate on different Radio Channels. This means that your 802.11g
wireless router or access point can co-exist with the WiRanger, if they
are configured to operate on different channels.
