CastleNet®Communications Network
The Prince Castle DHB Bins, external timers, and New Bun Cabinet
Timers can be inter-connected to form the CastleNet®Communication
Network. The network can be used for data transfer between bins and
timers for menu updates or to transfer product Hold time from bin-to-
bin. A PDA (or similar device) or a notebook with Prince Castle
MenuView®software is used to connect to the network and enter the
desired changes.
Each bin is supplied with a standard 25' cable and allows units to be
“daisy-chained” together to form the network. If cable is too short, use
Prince Castle Extender Cable Kit, P/N PC-COMEXT.
The factory default address for Main bins and timers is address 1. The
factory default address for Specialty bins and timers is address 2. If a
third bin is used, the address must be set at 3.
