GS-232A Computer Control Interface
for Yaesu Antenna Rotators
The
GS-232A
provide digital control of most models of
Yaesu antenna rotators
ø
from the serial port of an external
personal computer.
The
GS-232A
contains its own microprocessor with ROM
and RAM (memory), and a l0-bit analog-to-digital (A-D)
converter. The 3-wire async serial line can be configured for
serial data rates from 150 to 9600 baud. The
GS-232A
has a
DB-9 “male” connector for connection to the (RS-232C)
COM port of your computer. Purchase or construnct a
“straight” type serial cable, ensuring it has the correct gen-
der and number of pins for connection to your system.
Firmware on the
GS-232A
supports either direct keyboard
control, or commands from programs written specifically to
support it (software is not supplied by Yaesu). In addition
to reading and setting antenna angle and rotation speed,
the firmware includes clocked positioning routines to auto-

Please read this manual carefully to install the
GS-232A
. If
also installing a
G-400
,
G-500A
or
G-550
with the
GX-500
Automatic Control Adapter, follow the procedures in the
GX-500
manual before installing the
GS-232A
