Overview
As the hub of your Dolphin 7900 system, the Dolphin HomeBase charging and communication cradle supports both RS-232 and
USB communications, enabling your terminal to interface with the majority of PC-based enterprise systems.
Communications
RS-232 transmits data at speeds of up to 115 Kbps. With USB port, the data transmission rate goes up to 12 Mbps.
Dolphin HomeBases cannot be physically connected to each other–sometimes referred to as “daisy-chaining,” but
can be networked together via serial or USB hubs.
Convenient Storage
Intelligent battery charging makes the Dolphin HomeBase a safe and convenient storage receptacle for your
Dolphin terminal.
Capacity
The Dolphin HomeBase can charge two battery packs: one that’s installed in the terminal and another in the
auxiliary battery well. While charging the battery pack in the terminal, the HomeBase also powers the Dolphin
terminal. The auxiliary battery well located behind the terminal well charges a battery pack independently of the
terminal well.
Intelligent Battery Charging
The Dolphin HomeBase completes a full charge of the main battery pack in less than four hours.
In addition to charging, the HomeBase powers the intelligent battery charging system in the terminal that protects the battery
from being damaged by overcharging. The unit senses when a battery pack is fully charged and automatically switches to a trickle
charge that maintains the battery at full capacity.
As battery packs charge, the charging circuitry follows the two-step charging process (CC-CV) that is recommended for Li-Ion
batteries. The process monitors changes in temperature, current, and voltage.
As a result, Dolphin terminals may be stored in the HomeBase without damage to the terminals, battery packs, or peripherals.
Power Supply
The Dolphin HomeBase is available with US, UK, and European power supplies. Each version is designed to convert that voltage
from the power sources in each geography to the 9.5 volts DC required by the Dolphin terminal.
Use only the peripherals, power cables, and power adapters from Hand Held Products. Use of peripherals, cables, or
power adapters not sold/manufactured by Hand Held Products will void the warranty and may damage the terminal.
Use only the Li-ion battery packs provided by Hand Held Products. The use of any battery pack not sold/manufactured by
Hand Held Products in a Dolphin terminal will void your warranty and may result in damage to the Dolphin terminal or
battery.
