Dolphin® 7900 Series HomeBase™
Charging/Communication Cradle
The Dolphin HomeBase is a compact charging and communication 
cradle that seats one Dolphin 7900 mobile computer. In addition to 
charging and communication, it provides safe, convenient storage 
for a Dolphin terminal. 
This ergonomic cradle supports both USB (12 Mbps) and RS-232 
(up to 115 Kbps) communications, making it easy to integrate 
into the majority of PC-based enterprise systems. Its high-speed, 
direct USB connection is well-suited for batch applications that 
involve collecting large quantities and multiple types of data, such 
as 1D and 2D bar codes and images that use more sophisticated 
applications and databases. 
The HomeBase powers a seated terminal while charging its installed 
battery in less than four hours. The intelligent battery charging 
system incorporated into Dolphin terminals prevents over- and 
undercharging. The auxiliary battery well can charges a spare 
battery to be on-hand for power-intensive applications.
Like all Dolphin products, the HomeBase is ruggedized to withstand 
the harshest of environments yet sleek enough to be easy to handle. 
DIN rail slides along the bottom panel enable secure mounting 
to a desktop/bench while an available mounting bracket (ordered 
separately) enable secure wall-mounting.
Communications and charging status are easily monitored using 
the LEDs on the front panel. The DOCK LED indicates when the 
Dolphin terminal is properly seated in the HomeBase. The COMM 
LED displays the communication status between the seated 
Dolphin terminal and its host. The AUX BATTERY LED indicates the 
charging status of the spare battery.
