Star Linking Technology

Server Technology's PRO2 introduces Star Linking technology that supports the optional linking of up to three
expansion (link) units per one PRO2 master unit, allowing a single IP address for multiple cabinets.
Note: The Star Linking feature is available only with PRO2 products.
The following illustrations show multi-linking between separate units and within the cabinet:

Redundant Power and Communication
The Star Linking arrangement is fault tolerant, with redundant power coming from the first link unit. The
arrangement also offers significant cost reduction as the link units do not require a network card.
Another significant advantage of Star Linking technology is that if power in the master unit is lost, communication
will continue with the other link units – a major improvement over a daisy chain linking configuration.
Outlet Grouping
The multi-linking arrangement allows outlet grouping across the master and three link units.
Cable Length
The maximum cable length allowed from link unit to master unit is 21-feet.
Multi-Linking Module
In the Star Linking arrangement, the first PRO2 link unit connects via the PRO2 link port. However, the second and
third link units in the multi-linking arrangement attach to an optional T-shaped module that connects to the
® ®
Bluetooth port on the PRO2 master unit, while still allowing full functionality for Bluetooth mobile power
monitoring.
