3.3: Operate NEM software to connect to ACU devices
This section describes how to program the new ACU that has been installed on-site on an antenna. It needs
to use (PC+adaptor): the Antenna Line Configurator , listed in Table 1 (item 2). This procedure applies to every
ACU family and is divided into 5 steps, as depicted in the flowchart in Figure 5. The ACU-A20-S is chosen as an
example for describing those steps.
NOTICE
: Installation and use of NEM software, please refer to NEM-ALD-W User’s Manual.
