16.2.2 DefaultModuleConfiguration
From the factory, the Cyclone AP, SM, and BH are all configured to not transmit on any
frequency. This configuration ensures that you do not accidentally turn on an
unsynchronized module. Site synchronization of modules is required because
• Cyclone modules
• cannot transmit and receive signals at the same time.
• use TDD (Time Division Duplexing) to distribute signal access of the
downlink and uplink frames.
• when one module transmits while an unintended module nearby receives signal,
the transmitting module may interfere with or desense the receiving module. In
this context, interference is self-interference (within the same Cyclone network).
16.2.3 ComponentLayout
As shown in Figure 46, the base cover of the module snaps off when you depress a lever
on the back of the base cover. This exposes the Ethernet and GPS sync connectors and
diagnostic LEDs.
