RXT-320 Wireless Modbus ™
RXT-320 Wireless IM Rev. 2.1 Page 3 of 27
NOTE: If there are multiple Modbus™ networks in the same vicinity each system must reside
on a different RF Channel to keep data from one appearing on the other.
The 802.15.4 standard also implements a mesh network allowing any RXT-320 transceiver to relay or repeat
data between adjacent neighbors. This makes the network very robust and provides the following immediate
benefits:
 Allows re-routing of data in case of loss of a transceiver
 Allows re-routing around wireless obstacles
 Longer distances between transceivers because data can “hop” from one transceiver to the next
 Included in sensor, controller and alarm station transceivers
 RXT-320 transceivers can be deployed with less concern about physical location
