GS-232B Computer Control Interface
for Yaesu Antenna Rotators
The GS-232B provide digital control of most models of
Yaesu antenna rotatorsfrom the serial port of an external
personal computer.
The GS-232B contains its own microprocessor with a
l0-bit analog-to-digital (A-D) converter and EEPROM.
The async serial line can be configured for serial data
rates from 1200 to 9600 baud. The GS-232B has a DB-9
“male” connector for connection to the (RS-232C) COM
port of your computer. Purchase or construct a “straight”
type serial cable, ensuring it has the correct gender and
number of pins for connection to your system.
Firmware on the GS-232B supports either direct key-
board control, or commands from programs written spe-
cically to support it (software is not supplied by Yaesu).
In addition to reading and setting antenna angle and ro-
tation speed, the firmware includes clocked positioning
General Description
routines to automatically step the antenna through up to
3800 angles at programmable intervals, such as for track-
ing band openings or satellites (with an elevation rotator).
Please read this manual carefully to install the GS-232B.
If also installing a G-400, G-500A or G-550 with the
GX-500 Automatic Control Adapter, follow the proce-
dures in the GX-500 manual before installing the GS-
232B.
G-800DXA/G-1000DXA/G-2800DXA Azimuth Rotator,
G-800DXC/G-1000DXC/G-2800DXC Azimuth Rotator,
G-400 Azimuth Rotator,
G-500A/G-550 Elevation Rotator,
G-5400B/G-5600B/G-5500 Az-ElRotator, and
above Azimuth and Elevation rotator combination.
G-400 Azimuth Rotator and G-500A/G-550 Elevation Ro-
tator requires one GX-500 Automatic Control Adapter each.
