Setting Up For Communications
The Dolphin terminal and Dolphin Compact HomeBase support RS-232
communications through the RS-232 Main Communications Port on the back of the
Dolphin 7200 Compact HomeBase. The HomeBase translates the RS-232 signals
from the host computer into infrared signals to communicate with the Dolphin
Terminal.
The HomeBase 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.
Follow these steps to set up the Dolphin HomeBase and Dolphin Terminal for
communications:
1.
Set up the Dolphin Compact HomeBase.
2.
Set-up the Dolphin Terminal.
3.
Follow the data transfer sequence as described by your application.
Setting up the Dolphin Compact HomeBase
Set the Dolphin Compact HomeBase on any dry, stable surface such as a desktop.
Before mounting the Compact HomeBase, check to ensure that all AC wall
transformers have a nearby 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.
Connecting the Cables
Connect the Compact 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 RS-232 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.
