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-

programmable intervals, such as for tracking band open-
ings or satellites (with an elevation rotator).
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.
