The PVMax Expander™ is used to expand the capabilities of the PVMax Master™. This is achieved by cascading Expanders from the PVMax Master’s DOWN LINK ports.
Each PVMax Master DOWN LINK port is connected to a Level 1 PVMax Expander at a site. Many PVMax Expanders levels can be cascaded from the DOWN LINK ports of upper level PVMax Expanders. Each Level 1 PVMax Expander can be located in a separate site.
The PVMax Expander allows all devices connected to its DOWN LINK ports to communicate with all devices on its UP LINK port. The PVMax Expanders are the link between the PVMax Scanners and the PVMax Master thereby allowing the PVMax Master to communicate with all the PVMax Scanners in the system.
The PVMax Scanners are connected to the DOWN LINK ports of PVMax Expanders. Up to eight PVMax Scanners can be connected to each Expander. These Expanders are in turn connected to higher-level Expanders or directly to the PVMax Master/PVMax Master Expander, depending on the site configuration.
