OVERVIEW
2.1 OPERATING MODES
2.1.1 Subnet16™
Subnet16™ is an advanced feature-rich network protocol that supports a subset of the
Datalogic Automation MUX32 legacy protocol. The advanced features implemented in the
Subnet16 protocol allow the Gateway to assign individual Node ID values automatically to
each RFID controller connected on the Subnet bus. Subnet16 also allows the Gateway to
detect when a new controller is connected to the Subnet or when a controller “falls off the
bus” (stops responding).
Through the Subnet16 protocol, the Gateway is able to store a backup copy of each RFID
controller’s custom configuration settings. In the event that an RFID controller fails, the
stored configuration settings can be automatically reassigned to a replacement RFID
controller.
Real-time clock functionality is supported in Subnet16 mode. Host-bound data packets are
automatically Time/Date stamped as they pass through the Gateway and on to the host.
NOTE
The Gateway communicates over the RS485 physical layer using Subnet16,
but it is not a generic RS485 device. RS485 cabling requirements are
however the same.
