Installing The Charging/Communication Cradle
To install and use the HomeBase, IntelliBase or IntelliBase+, you need the following equipment:
• HomeBase/IntelliBase/IntelliBase+ with power supply
• Serial cable
Set the Dolphin HomeBase/IntelliBase/IntelliBase+ 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/
IntelliBase.
Connecting the Cables
Connect the HomeBase/IntelliBase/IntelliBase+ 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/IntelliBase 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.
The HomeBase/IntelliBase/IntelliBase+ cannot be daisy-chained.
Connect the power supply to the charging/communication cradle. Plug the AC transformer into the Dolphin HomeBase/
IntelliBase/IntelliBase+ 5 Volt DC power supply connector. The AC wall transformer provided can power only one HomeBase/
IntelliBase/IntelliBase+. HHP recommends that you leave the Dolphin HomeBase/IntelliBase/IntelliBase+ connected to its power
source at all times, so that it is always ready to use.
Set the baud rate switch to the communication mode you are going to use. Refer to Table 2 for HomeBase switch settings or
Table 3 for IntelliBase/IntelliBase+ switch settings.
