Example Multidrop STAR-System™ Network with OM-3000 as Master
In this layout an OM-3000 cradle acts as the Master. The Host is connected to the
OM-3000 Master using any one of the multi-standard interfaces (RS232, USB,
WEDGE, or PEN Emulation). The Master is then connected to the slaves in the RS485
network. In this way the slave cradles provide communications between a single Host
and all readers in the system. STARGATE™ base stations can also be used as slaves
in this network. The devices at the ends of the network must be terminated (see par.
2.8.3).
See pars. 4.6 and 4.7 or the Datalogic Aladdin™ Help On-Line for system
configuration specifications.
