Dolphin Charging/Communication Cradles
Hub of the System
As the hub of your Dolphin system, Dolphin Charging/Communication cradles perform three important functions – power
conditioning, communications and storage. Four versions of the charging/communications cradle are available:
• HomeBase for communicating with PC-based equipment using a half duplex serial mode
• IntelliBase for communicating with devices such as printers and modems without integrated IrDA protocol software
• IntelliBase+ for communicating with devices without integrated IrDA protocol software and charging and conditioning a spare
battery
• USB HomeBase for communicating directly with a USB-compatible host computer
Power Conditioning
Dolphin charging/communication cradles provide power to the intelligent battery charging system incorporated into Dolphin
terminals.
The IntelliBase+ has an auxiliary battery well, located on the back of the cradle, allowing users to charge and condition a spare
battery.
Ir/IrDA Optical Communications
The infrared, or Ir communications port, on the HomeBase, IntelliBase, and IntelliBase+ connects with the IrDA port on the
Dolphin terminal. With no pins or contacts to break, Ir will work reliably for years. Reliable data communications at speeds of up
to 115k baud can be transmitted by the HomeBase, IntelliBase and IntelliBase+; data transmission rates with the USB HomeBase
up to 4Mbps are possible but, at this time, are limited to 115 kbps as the Dolphin 7400 does not currently support 4 Mbps data
transfer.
The IntelliBase and IntelliBase+ infrared connection to the terminal uses IrDA-compliant hardware and software for a reliable
connection. Communications between the HomeBase and other devices occur at half duplex serial mode. Half duplex refers to
the transmission of data in just one direction at a time.
The USB HomeBase enables direct communication with USB-compatible host computers at rates of up 115 kbps. The USB
HomeBase also is IrDA 1.3 compliant.
These peripherals cannot be “daisy-chained” but can be networked together using a serial or USB hub.
Convenient Storage
Dolphin charging/communication peripherals provide a safe and convenient storage receptacle for your Dolphin terminal.
