4. LX200 Demo Program
The RS-232 interface communicates with your computer at 9600
Baud Rate, Parity = None, 8 Data Bits, 1 Stop Bits. For those who
are familiar with programming, the LX200 Command Set is written in
ASKII character format and can be used to write your own programs.
The LX200 Demo Program on the following pages, is written in Quick
Basic and is intended to demonstrate how commands are sent to the
telescope and information is received from the telescope. It is not a
"polished" program and does not incorporate all of the RS-232
The program is set-up to operate on serial port 2 (COM2:). To
operate on serial port 1 (COM1:) line 4 should be changed from
"COM2:" to "COM1:." The program is as follows:
counter = 0
FOR RANDOM AS #1

Please note that Meade Instruments does not support these
programs, or programs that you may write in any way. For
questions relating to after-market software programs, refer back
to those manufacturers.
Meade does recommend and support our Epoch 2000sk software
package which is fully compatible with the LX200 telescope (Fig.
30). This program presents on the display of a personal computer
an incredibly detailed simulation of the entire sky, including up to
281,000 celestial objects
Epoch 2000 allows the presentation of the most complex starfields
just as they actually appear through the telescope. This software
is available for Windows 3.1 or higher, including Windows 95.
