CastleNet® Communications Network

The Prince Castle DHB-BK Bins and Retro Bun Timer and New Bun
Cabinet Timers can be inter-connected to form the CastleNet

®

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.
The factory default address for the Retro Bun Timer is bunF.
