Establishing Communication with the Mobile Base
The Mobile Base RS-232 interface allows the Dolphin terminal to communicate to a personal computer, modem, or any standard
RS-232 device using a standard serial cable and communications software.
Requirements
To use the HomeBase for communications, you need the following equipment:
• A Mobile Base powered by a power cable and power adapter cable from Hand Held Products
• The RS-232 communications cable
• ActiveSync v4.1 or above on the host workstation
•Windows
®
98 Second Edition*, Windows
®
Me, Windows
®
2000, or Windows
®
XP on the host workstation
To Install the Mobile Base for Communication
Note: You must be using ActiveSync 4.1 or higher.
1. Plug in the power supply and connect it to the back of the Mobile Base.
2. Plug the RS-232 communication cable into the back of the Mobile Base.
3. Connect the communication cable into the back of the workstation.
4. At this point, the hardware is installed and operating.
You may need to reboot your workstation to complete the installation process.
Establishing ActiveSync Communication with the Mobile Base
The Dolphin terminal is usually auto-detected and configured by ActiveSync based on the communication cable. If you are using
an RS-232 cable, ActiveSync will usually set up an RS-232 connection.
For more details, see Establishing ActiveSync Communication on page 7-2.
Connecting the Cables
Connect the Mobile Base to the host computer or other device by plugging an RS-232 serial cable into the RS-232
Communications Port on the bottom of the Mobile Base. Plug the other end of the RS-232 serial cable into the correct port on
the host RS-232 device.
The wiring of your cable depends on whether the other device is set up as a Data Communications Equipment (DCE) or Data
Terminal Equipment (DTE) device.
The Mobile Base 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.
