EXTERNAL STARTUP SEQUENCE – FOR COMPUTER CONTROLLED
MOUNTS
“Auto-Connect: EXT” is a simplied startup sequence appropriate for mounts that meet both of these requirements:
● Precisely polar-aligned
● Your mount is connected to a computer with telescope control software
This feature can be activated or de-activated in the Auto-Connect settings in the
Keypad Options Menu. You can access this menu by pressing “2=Setup”, then
pressing “3=Keypad Options” to enter into the Keypad Options menu. Press “1” to
toggle between: “YES”, “NO”, and “EXT”.
Once Auto-Connect is set to “EXT”, press the Menu button until you get to the Main Menu, and then power cycle the mount
(power off, wait 10–15 seconds, then power on) in order to activate this feature.
1. Prepare your computer and software. Ensure that your computer is connected to the mount. The CP1/2/3 will
connect via a serial cable to the top serial port on the control box. The CP4 has multiple options from which to choose
(see the Servo manual for explanations of the options). Check your computer’s Device Manager to see which COM
port number to choose for the software connection.
2. Power up your Mount and the External Startup Screen will appear on the Keypad. This screen will check the
mount every few seconds to see if the computer has sent it the location and time data it needs to complete the startup
(initialization) process. It will patiently wait for the software connection.
3. Connect to your mount in the computer software. Once you make the software connection to the mount, initializa-
tion via the computer will take place and the display on the Keypad will change to the Main Menu.
4. The Mount will now show the Main Menu and you are ready to use the Keypad or the computer. If your tel-
escope was moved since last time you used it, you may need to re-calibrate on a star. Refer to “Auto-Start Sequence
– For Permanent, Polar-Aligned Mounts” in your GTO Keypad manual for this procedure.
Important Points
● If you have used the External Startup Sequence, do not attempt to change the time on your Keypad. Use the
computer program to control the time.
● If your Keypad is set to “AutoConnect: EXT”, but you wish to start up
manually, then push “Menu” and follow the procedure.
