Verifying that the Wireless is Active
Read the “WACTIVE” Gateway Coil. (Function Code
address = 1, Raw Address = 0). A true coil denotes that
the system is configured sufficiently to communicate to
wireless device(s). A false coil means the gateway does
not have any registered wireless devices (WDL is empty).
