The PVMax Master Expander™ is a combination of the PVMax Master™ and the PVMax Expander™. It contains all the modules of the PVMax Master as well as the PVMax Expander’s features. Only a single site can be defined when a PVMax Master Expander is used. The Master Expander cannot be connected to a PVMax Master.
The PVMax Master Expander can communicate with all devices connected to its 8 DOWN LINK ports. PVMax Expanders or PVMax Scanners are directly connected to one of the DOWN LINK ports located on the PVMax Master Expander’s front panel.
The PVMax Scanners are connected to the PVMax Expander’s DOWN LINK ports. Up to eight PVMax Scanners can be connected to each Expander. These PVMax Expanders are in turn connected to higher-level PVMax Expanders or directly to the PVMax Master Expander, depending on the site’s configuration.
