Once you have configured all radios, your network should be setup similar to the one shown in Figure 22 below. The
main server or hop master will need to be powered on anytime that the other servers are connected or they will never
synchronize and will not be able to communicate with their clients. If a centralized network will not work and all
servers will not be in range of the hop master, a daisy chain network can be utilized as shown in Figure 23.
