3.2 MULTIDROP STAR-SYSTEM™ NETWORK LAYOUTS
Even though many stand-alone systems can operate in the same physical area without
interfering with each other, it may be desirable to bridge data from multiple base
stations in a network to a single Host. PowerScan
® M8300 readers are compatible with
STAR-System™ networks. These networks provide seamless active roaming for any
RF reading device in the system.

A. Host Master with STAR-Link™
B. STAR-Box™ converter
C. BC-8060 slave cradles
D. STARGATE™ base stations
Example Multidrop STAR-System™ Network with Host as Master
In this layout the Host acts as the Master using STAR-Link™ software. The Host is
connected in RS-232 to a STAR-Box™ converter, which is connected to the first slave
in the RS-485 network. In this way the base stations provide communications between
a single Host and all readers in the system. STARGATE™ base stations are used as
slaves in this network. The Slaves at the ends of the network must be terminated (see
the STARGATE™ and STAR-Box™ Installation Manuals and par. 2.8.3).
See par. 4.6 and 4.7 or the Datalogic Aladdin™ Help On-Line for system
configuration specifications.
