DRAGON™ M131 SYSTEM AND NETWORK LAYOUTS
21
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. Dragon™ M131 readers are compatible with
STAR-System™ networks. These networks provide seamless active roaming for any
RF reading device in the system.
3.2.1 Host Master Layout
A. Host Master with STAR-Link™
B. STAR-Box™ converter
C. OM-3000 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 RS232 to a STAR-Box™ converter which is connected to the first slave in
the RS485 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.
