GS-232B Computer Control Interface
for Yaesu Antenna Rotators
The GS-232B provide digital control of most models of
Yaesu antenna rotators" frolll the serial port of an external
personal computer.
The GS-2328 contains its O\\ln microprocessor with a to-
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 aD8-9 "male" con-
nector
for connection to the (RS-232 ) 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 (he G5-2328 SUppOr1S either direct keyboard
control, or commands frol11 programs written specifically
10 support it (software is not supplied by Yaesu). In addi-
lion
to reading and setting antenna angle and rotation speed,
the firmware includes clocked positioning routines (0 auto-
matically step the antenna through up to 3800 angles at pro-
grammable intervals, such as for tracking band openings or
satellites (with an elevation rotator).
Please read this lIlanual carefully to install the GS-232B.
Ifalso installing aG-400, G-SOOA or G-SSO with the GX-
500 Automatic Control Adapter, follow the procedures in
the GX-SOO manual before installing the GS-232B.
