Figure 14: Basic point-to-point network
A single master unit and a single slave unit are configured such that:
The have the same hopping pattern, network address, and security code.
The master and slave have different local addresses.
Both the master and slave have the point-to-point protocol selected on their main serial port.
The point-to-point destination address on the slave is set to the master’s local address, while the
point-to-point destination address on the master is set to the slave’s local address.
6.2 Simplex Point-to-point Network
A simplex point-to-point network is the same as a basic point-to-point network, except that user data is only
going to flow in a single direction. This situation is shown in Figure 15, where user data is only flowing
from the slave to the master unit.
