After installation and calibration, the Control Interface can
accept commands entered directly from the keyboard, or
from a program written specifically to support it (not sup-
plied by Yaesu). For brief summaries of the commands rec-
ognized by the Control Interface, press [
H
]
Ž
[
↵
] for a list
of azimuth commands, or [
H2
]
Ž
[
↵
] for elevations com-
mands. Keep in mind that all commands require that the
E
NTER
key be pressed after the command letter (or “
0D
h”
be sent by a control program), although we will not repeat
this when discussing the commands. Also note that any
command letter may be sent in either upper or lower case.
The info screens shown on the next page will be returned
by the Control Interface.
Most commands have two versions: one for azimuth, and
one for elevation. Commands are not echoed by the Control
Interface, but a carriage return character (“
0D
h”) is returned
after every command, and also a line feed character (“
0A
h”)
if the command invoked returned data. Invalid commands
cause “
?
>
” to be returned and the input buffer cleared.
Note that all angles are in degrees, beginning with zero at
the most counterclockwise azimuth (or horizontal elevation).
Angles sent to the Control Interface must be 3 digits long
(left-zero-padded), and angles returned will, in some cases,
be 4 digits long with a leading “+
0
.”
If you wish, you can mount the
GS-232A
on top of your
Rotator Controller using the two supplied hook-and-loop
fastener strips. Just remove the backing from one side of
each strip, and press into place on the bottom of the
GS-
232A
. Then remove the backing from the other side, and
press the
GS-232A
into place on the Controller.
