The HomeBase charging/communication cradle provides power to the intelligent battery charging system incorporated into 
Dolphin 9500/9550 terminals.  This charging method protects the battery from being damaged by overcharging.  Therefore, 
Dolphin terminals may be stored indefinitely in the charging/communication cradles without damage to the terminals, battery 
packs, or peripherals.

To charge a Dolphin terminal, follow these steps:

1. Insert a battery pack into the Dolphin terminal.

2. Place the terminal, imager window up and the LCD visible, in the terminal well of the cradle.  

3. Let it glide down into the well until it stops.  

4. Once the Dolphin terminal is properly seated, the Dock LED on the front of the cradle will be solid GREEN.

The auxiliary battery well located on the back of the HomeBase allows users to charge a spare battery.  Charging a Dolphin 
terminal and a spare battery pack can be done simultaneously as the charging slots work independently to control the charging 
of the individual batteries.  The HomeBase senses when a battery pack is fully charged and automatically switches  to maintain 
the battery at full capacity indefinitely.

To charge a spare battery in the Aux Well, insert the end of the battery without the locking tab into the bottom of the auxiliary well 
opening and snap the battery into place with a hinging motion.  Once the battery is inserted, you can use the AUX BATTERY 
LED to monitor the charging progress.  

The HomeBase supports RS-232 communications through the RS-232 Communications Port located on the back of the 
device.The HomeBase interfaces the RS-232 signals from the host computer to the RS-232 signals of the Dolphin 9500/9550 
mobile computer.  

The HomeBase’s RS-232 interface allows the Dolphin terminal to communicate to a personal computer, modem, or any RS-232 
device using a standard serial cable and communications software.

The HomeBase also supports USB communications through the USB port located on the back.  The HomeBase acts as a USB 
device, and interfaces the USB signals of the Dolphin 9500/9550 to the USB of the host computer.  Using a standard USB cable, 
the HomeBase’s USB interface allows the Dolphin terminal to communicate with a personal computer or to be networked through 
a USB hub.

Note: The HomeBase should have only one type of interface cable connected at a time, either USB or RS-232.

To install and use the HomeBase, you need the following equipment:

•

HomeBase with power supply

•

Serial cable

Set the Dolphin HomeBase on a dry, stable surface, such as a desktop near an electrical outlet.  Be sure to provide enough 
workspace with good lighting for the user to view and operate the Dolphin terminal while it is in the HomeBase.

Connect the HomeBase to the host computer or other device by plugging an RS-232 serial cable into the RS-232 
Communications Port on the rear of the HomeBase.  The wiring of your cable depends on whether the other device is set up as 
a DCE (Data Communications Equipment) or DTE (Data Terminal Equipment) device.  

The HomeBase Communication Port is configured as a DCE device.  To communicate with a DTE device such as a computer, 
use a standard (or straight-through) RS-232 cable.  To communicate with a DCE device, use either a null modem adapter in line 
with a standard RS-232 cable, or a null-modem serial cable.  

You can make your own cables by following the pin configuration in the chart below.  To do so, you must determine if your host 
RS-232 device is 9-pin or 25-pin, and whether it is configured as a DCE or DTE device.
