Serial Connector
The following diagram displays the pin diagram of the serial connector of the base.
Note: The signal names are referenced to the terminal. The terminal is a DCE RS232 device. Refer to section,
RS232 Communications Cables and RS232 Pin Configuration for more details. The base is at a right-angle
to the printed circuit board (PCB). The ninth pin has a ring indicator (RI).
Mounting the HomeBase
Set the base on a dry, stable surface, such as a desktop or workbench 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 base.
When choosing a mounting location, bear in mind that the location must allow users' easy access to the
Auxiliary Battery Well and the back panel of the HomeBase where the serial port, USB port, and the
power jack are located.
Desk Mounting
The DIN rail slot (7.5 X 35 mm) may be mounted
on the bottom to allow for secure desk attachment
of the unit if desired.
