Datanet Network Architecture - Fourier DataNet User Manual

2.1. DataNet Network
Architecture
The DataNet network architecture consists of layers of loggers
and Repeaters, forming a mesh network monitored by the
Receiver unit connected to the workstation PC.
The basic architecture is as follows:
•
Maximum nodes on network: 65,000
•
DNR900 Receiver recognizes up to 8 loggers and 16
Repeaters
•
DNR900 Repeater and DNR800 Mini Repeater
recognizes up to 24 loggers and 16 Repeaters (including
parent unit)
•
DNL910 and DNL920 (including the PA models) in Short
Range Repeater mode (refer to section 2.8.5) recognizes
up to 24 loggers and 16 Repeaters
The diagrams below show the architecture of a typical
DataNet mesh network. Repeaters and loggers, which are
being used as Short Range Repeaters in Figure 4 (see
section), can be added to the network in order to extend the
range and improve its robustness. Each such device has end
units communicating with it, but this route may change as the
RF environment changes. This is the ZigBee's self correcting
mechanism at play.
