GS-232A Computer Control Interface
for Yaesu Antenna Rotators
The GS-232A provide digital control of most models of
Yaesu antenna rotatorsø 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 gender 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-
matically step the antenna through up to 3800 angles at
programmable intervals, such as for tracking band openings 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 .

ACCESSORIES & OPTION

During installation, a personal computer with a serial port
and terminal software is required to calibrate trimmers on
the Controller and on the Control Interface. Any simple interactive terminal program can be used - it only has to transmit keystrokes as typed, and display characters received
from the GS-232A.
INSTALLATION
POWER & CONTROL CONNECTIONS
DXA or DXC Series Azimuth Rotator
Connect the supplied DC cable to a source of 12 VDC.
r
The red lead connects to the Positive (+) DC terminal,
and the black lead connects to the Negative
(–) DC terminal. The GS-232A requires 110 mA. The
supplied cable has a 500-mA fast-blow fuse. Use only
the same type fuse for replacement.
Plug the coaxial power connector into the DC 12V jack
r
on the GS-232A rear panel.
Connect the supplied Control cable (“5-pin” 1 “Mini-
r
DIN”) between the EXT CONTROL connector on the
rotator’s controller and AZ connector on the rear panel
of the GS-232A (Figure 1).
